– Ways of knowing (HOS 4)

How do we know what we know?

This article considers:

(1) the ways we come to believe what we think we know

(2) the many issues with the validation of our beliefs

(3) the implications for building artificial intelligence and robots based on the human operating system.


I recently came across a video (on the site http://www.theoryofknowledge.net) that identified the following ‘ways of knowing’:

  • Sensory perception
  • Memory
  • Intuition
  • Reason
  • Emotion
  • Imagination
  • Faith
  • Language

This list is mainly about mechanisms or processes by which an individual acquires knowledge. It could be supplemented by other processes, for example, ‘meditation’, ‘science’ or ‘history’, each of which provides its own set of approaches to generating new knowledge for both the individual and society as a whole. There are many difference ways in which we come to formulate beliefs and understand the world.

Youtube Video, Theory of Knowledge: Ways of Knowing, New College of Humanities, December 2014, 9:32 minutes


In the spirit of working towards a description of the ‘human operating system’, it is interesting to consider how a robot or other Artificial Intelligence (AI), that was ‘running’ the human operating system, would draw on its knowledge and beliefs in order to solve a problem (e.g. resolve some inconsistency in its beliefs). This forces us to operationalize the process and define the control mechanism more precisely. I will work through the above list of ‘ways of knowing’ and illustrate how each might be used.


Let’s say that the robot is about to go and do some work outside and, for a variety of reasons, needs to know what the weather is like (e.g. in deciding whether to wear protective clothing, or how suitable the ground is for sowing seeds or digging up for some construction work etc.) .

First it might consult its senses. It might attend to its visual input and note the patterns of light and dark, comparing this to known states and conclude that it was sunny. The absence of the familiar sound patterns (and smell) of rain might provide confirmation. The whole process of matching the pattern of data it is receiving through its multiple senses, with its store of known patterns, can be regarded as ‘intuitive’ because it is not a reasoning process as such. In the Khanemman sense of ‘system 1’ thinking, the robot just knows without having to perform any reasoning task.

Youtube Video, System 1 and System 2, Stoic Academy, February 2017, 1:26 minutes

The knowledge obtained from matching perception to memory can nevertheless be supplemented by reasoning, or other forms of knowledge that confirm or question the intuitively-reached conclusion. If we introduce some conflicting knowledge, e.g. that the robot thinks it’s the middle of the night in it’s current location, we then create a circumstance in which there is dissonance between two sources of knowledge – the perception of sunlight and the time of day. This assumes the robot has elaborated knowledge about where and when the sun is above the horizon and can potentially shine (e.g. through language – see below).

In people the dissonance triggers the emotional state of ‘surprise’ and the accompanying motivation to account for the contradiction.

Youtube Video, Cognitive Dissonance, B2Bwhiteboard, February 2012, 1:37 minutes

Likewise, we might label the process that causes the search for an explanation in the robot as ‘surprise’. An attempt may be made to resolve this dissonance through Kahneman’s slower, more reasoned, system 2 thinking. Either the perception is somehow faulty, or the knowledge about the time of day is inaccurate. Maybe the robot has mistaken the visual and audio input as coming from its local senses when in fact the input has originated from the other side of the world. (Fortunately, people do not have to confront the contradictions caused by having distributed sensory systems).

Probably in the course of reasoning about how to reconcile the conflicting inputs, the robot will have had to run through some alternative possible scenarios that could account for the discrepancy. These may have been generated by working through other memories associated with either the perceptual inputs or other factors that have frequently led to mis-interpretations in the past. Sometimes it may be necessary to construct unique possible explanations out of component part explanations. Sometimes an explanation may emerge through the effect of numerous ideas being ‘primed’ through the spreading activation of associated memories. Under these circumstances, you might easily say that the robot was using it’s imagination in searching for a solution that had not previously been encountered.

Youtube Video, TEDxCarletonU 2010 – Jim Davies – The Science of Imagination, TEDx Talks, September 2010, 12:56 minutes

Lastly, to faith and language as sources of knowledge. Faith is different because, unlike all the other sources, it does not rely on evidence or proof. If the robot believed, on faith, that the sun was shining, any contradictory evidence would be discounted, perhaps either as being in error or as being irrelevant. Faith is often maintained by others, and this could be regarded as a form of evidence, but in general if you have faith in or trust something, it is at least filling the gap between the belief and the direct evidence for it.

Here is a religious account of faith that identifies it with trust in the reliability of God to deliver, where the main delivery is eternal life.

Youtube video, What is Faith – Matt Morton – The Essence of Faith – Grace 360 conference 2015,Grace Bible Church, September 2015, 12:15 minutes

Language as a source of evidence is a catch-all for the knowledge that comes second hand from the teachings and reports of others. This is indirect knowledge, much of which we take on trust (i.e. faith), and some of which is validated by direct evidence or other indirect evidence. Most of us take on trust that the solar system exists, that the sun is at the centre, and that earth is in the third orbit. We have gained this knowledge through teachers, friends, family, tv, radio, books and other sources that in their turn may have relied on astronomers and other scientist who have arrived at these conclusions through observation and reason. Few of us have made the necessary direct observations and reasoned inferences to have arrived at the conclusion directly. If our robot were to consult databases of known ‘facts’, put together by people and other robots, then it would be relying on knowledge through this source.

Pitfalls

People like to think that their own beliefs are ‘true’ and that these beliefs provide a solid basis for their behaviour. However, the more we find out about the psychology of human belief systems the more we discover the difficulties in constructing consistent and coherent beliefs, and the shortcomings in our abilities to construct accurate models of ‘reality’. This creates all kinds of difficulties amongst people in their agreements about what beliefs are true and therefore how we should relate to each other in peaceful and productive ways.


If we are now going on to construct artificial intelligences and robots that we interact with and have behaviours that impact the world, we want to be pretty sure that the beliefs a robot develops still provide a basis for understanding their behaviour.


Unfortunately, every one of the ‘ways of knowing’ is subject to error. We can again go through them one by one and look at the pitfalls.

Sensory perception: We only have to look at the vast body of research on visual illusion (e.g. see ‘Representations of Reality – Part 1’) to appreciate that our senses are often fooled. Here are some examples related to colour vision:

Youtube Video, Optical illusions show how we see | Beau Lotto,TED, October 2009, 18:59 minutes

Furthermore, our perceptions are heavily guided by what we pay attention to, meaning that we can miss all sorts of significant and even life-threatening information in our environment. Would a robot be similarly misled by its sensory inputs? It’s difficult to predict whether a robot would be subject to sensory illusions, and this might depend on the precise engineering of the input devices, but almost certainly a robot would have to be selective in what input it attended to. Like people, there could be a massive volume of raw sensory input and every stage of processing from there on would contain an element of selection and interpretation. Even differences in what input devices are available (for vision, sound, touch or even super-human senses like perception of non-visual parts of the electromagnetic spectrum), will create a sensory environment (referred to as the ‘umwelt’ or ‘merkwelt’in ethology) that could be quite at variance with human perceptions of the world.

YouTube Video, What is MERKWELT? What does MERKWELT mean? MERKWELT meaning, definition & explanation, The Audiopedia, July 2017, 1:38 minutes


Memory: The fallibility of human memory is well documented. See, for example, ‘The Story of Your Life’, especially the work done by Elizabeth Loftus on the reliability of memory. A robot, however, could in principle, given sufficient storage capacity, maintain a perfect and stable record of all its inputs. This is at variance with the human experience but could potentially mean that memory per se was more accurate, albeit that it would be subject to variance in what input was stored and the mechanisms of retrieval and processing.


Intuition and reason: This is the area where some of the greatest gains (and surprises) in understanding have been made in recent years. Much of this progress is reported in the work of Daniel Kahneman that is cited many times in these writings. Errors and biases in both intuition (system 1 thinking) and reason (system 2 thinking) are now very well documented. A long list of cognitive biases can be found at:

https://en.wikipedia.org/wiki/List_of_cognitive_biases

Would a robot be subject to the same type of biases? It is already established that many algorithms, used in business and political campaigning, routinely build in the biases, either deliberately or inadvertently. If a robot’s processes of recognition and pattern matching are based on machine learning algorithms that have been trained on large historical datasets, then bias is virtually guaranteed to be built into its most basic operations. We need to treat with great caution any decision-making based on machine learning and pattern matching.

Youtube Vide, Cathy O’Neil | Weapons of Math Destruction, PdF YouTube, June 2015, 12:15 minutes

As for reasoning, there is some hope that the robustness of proofs that can be achieved computationally may save the artificial intelligence or robot from at least some of the biases of system 2 thinking.


Emotion: Biases in people due to emotional reactions are commonplace. See, for example:

Youtube Video, Unconscious Emotional Influences on Decision Making, The Rational Channel, February 2017, 8:56 minutes

However, it is also the case that emotions are crucial in decision–making. Emotions often provide the criteria and motivation on which decisions are made and without them, people can be severely impaired in effective decision-making. Also, emotions provide at least one mechanism for approaching the subject of ethics in decision-making.

Youtube Video, When Emotions Make Better Decisions – Antonio Damasio, FORA.tv, August 2009, 3:22 minutes

Can robots have emotions? Will robots need emotions to make effective decisions? Will emotions bias or impair a robot’s decision-making. These are big questions and are only touched on here, but briefly, there is no reason why emotions cannot be simulated computationally although we can never know if an artificial computational device will have the subjective experience of emotion (or thought). Probably some simulation of emotion will be necessary for robot decision-making to align with human values (e.g. empathy) and, yes, a side-effect of this may well be to introduce bias into decision-making.

For a selection of BBC programmes on emotions see:
http://www.bbc.co.uk/programmes/topics/Emotions?page=1


Imagination: While it doesn’t make much sense to talk about ‘error’ when it comes to imagination, we might easily make value-judgments about what types of imagination might be encouraged and what might be discouraged. Leaving aside debates about how, say excessive experience of violent video games, might effect imagination in people, we can at least speculate as to what might or should go on in the imagination of a robot as it searches through or creates new models to help predict the impacts of its own and others behaviours.

A big issue has arisen as to how an artificial intelligence can explain its decision-making to people. While AI based on symbolic reasoning can potentially offer a trace describing the steps it took to arrice at a conclusion, AIs based on machine learning would be able to say little more than ‘I recognized the pattern as corresponding to so and so’, which to a person is not very explanatory. It turns out that even human experts are often unable to provide coherent accounts of their decision-making, even when they are accurate.

Having an AI or robot account for its decision-making in a way understandable to people is a problem that I will address in later analysis of the human operating system and, I hope, provide a mechanism that bridges between machine learning and more symbolic approaches.


Faith: It is often said that discussing faith and religion is one of the easiest ways to lose friends. Any belief based on faith is regarded as true by definition, and any attempt to bring evidence to refute it, stands a good chance of being regarded as an insult. Yet people have different beliefs based on faith and they cannot all be right. This not only creates a problem for people, who will fight wars over it, but it is also a significant problem for the design of AIs and robots. Do we plug in the Muslim or the Christian ethics module, or leave it out altogether? How do we build values and ethical principles into robots anyway, or will they be an emergent property of its deep learning algorithms. Whatever the answer, it is apparent that quite a lot can go badly wrong if we do not understand how to endow computational devices with this ‘way of knowing’.


Language: As observed above, this is a catch-all for all indirect ‘ways of knowing’ communicated to people through media, teaching, books or any other form of communication. We only have to consider world wars and other genocides to appreciate that not everything communicated by other people is believable or ethical. People (and organizations) communicate erroneous information and can deliberately lie, mislead and deceive.

We strongly tend to believe information that comes from the people around us, our friends and associates, those people that form part of our sub-culture or in-group. We trust these sources for no other reason than we are familiar with them. These social systems often form a mutually supporting belief system, whether or not it is grounded in any direct evidence.

Youtube Video, The Psychology of Facts: How Do Humans (mis)Trust Information?, YaleCampus, January 2017

Taking on trust the beliefs of others that form part of our mutually supporting social bubble is a ‘way of knowing’ that is highly error prone. This is especially the case when combined with other ‘ways of knowing’, such as faith, that in their nature cannot be validated. Will robot communities develop, who can talk to each other instantaneously and ‘telepathically’ over wireless connections, also be prone to the bias of groupthink?


The validation of beliefs

So, there are multiple ways in which we come to know or believe things. As Descartes argued, no knowledge is certain (see ‘It’s Like This’). There are only beliefs, albeit that we can be more sure of some that others, normally by virtue of their consistency with other beliefs. Also, we note that our beliefs are highly vulnerable to error. Any robot operating system that mimics humans will also need to draw on the many different ‘ways of knowing’ including a basic set of assumptions that it takes to be true without necessarily any supporting evidence (it’s ‘faith’ if you like). There will also need to be many precautions against AIs and robots developing erroneous or otherwise unacceptable beliefs and basing their behaviours on these.

There is a mechanism by which we try to reconcile differences between knowledge coming from different sources, or contradictory knowledge coming from the same source. Most people seem to be able to tolerate a fair degree of contradiction or ambiguity about all sorts of things, including the fundamental questions of life.

Youtube Video, Defining Ambiguity, Corey Anton, October 2009, 9:52 minutes

We can hold and work with knowledge that is inconsistent for long periods of time, but nevertheless there is a drive to seek consistency.

In the description of the human operating system, it would seem that there are many ways in which we establish what we believe and what beliefs we will recruit to the solving of any particular problem. Also, the many sources of knowledge may be inconsistent or contradictory. When we see inconsistencies in others we take this as evidence that we should doubt them and trust them less.

Youtube Video, Why Everyone (Else) is a Hypocrite, The RSA, April 2011, 17:13 minutes

However, there is, at least, a strong tendency in most people, to establish consistency between beliefs (or between beliefs and behaviours), and to account for inconsistencies. The only problem is that we are often prone to achieve consistency by changing sound evidence-based beliefs in preference to the strongly held beliefs based on faith or our need to protect our sense of self-worth.

Youtube Video, Cognitive dissonance (Dissonant & Justified), Brad Wray, April 2011. 4:31 minutes

From this analysis we can see that building AIs and robots is fraught with problems. The human operating system has evolved to survive, not to be rational or hold high ethical values. If we just blunder into building AIs and robots based on the human operating system we can potentially make all sorts of mistakes and give artificial agents power and autonomy without understanding how their beliefs will develop and the consequences that might have for people.

Fortunately there are some precautions we can take. There are ways of thinking that have been developed to counter the many biases that people have by default. Science is one method that aims to establish the best explanations based on current knowledge and the principle of simplicity. Also, critical thinking has been taught since Aristotle and fortunately many courses have been developed to spread knowledge about how to assess claims and their supporting arguments.

Implications

To summarise:

Sensory perception – The robot’s ‘umwelt’ (what it can sense) may well differ from that of people, even to the extent that the robot can have super-human senses such as infra-red / x-ray vision, super-sensitive hearing and smell etc. We may not even know what it’s perceptual world is like. It may perceive things we cannot and miss things we find obvious.

Memory – human memory is remarkably fallible. It is not so much a recording, as a reconstruction based on clues, and influenced by previously encountered patterns and current intentions. Given sufficient storage capacity, robots may be able to maintain memories as accurate recording of the states of their sensory inputs. However, they may be subject to similar constraints and biases as people in the way that memories are retrieved and used to drive decision-making and behaviour.

Intuition – if the robot’s pattern-matching capabilities are based on the machine learning of historical training sets then bias will be built into its basic processes. Alternatively, if the robot is left to develop from it’s own experience then, as with people, great care has to be taken to ensure it’s early experience will not lead to maladaptive behaviours (i.e. behaviours not acceptable to the people around it).

Reason – through the use of mathematical and logical proofs, robots may well have the capacity to reason with far greater ability than people. They can potentially spot (and resolve) inconsistencies arising out of different ‘ways of knowing’ with far greater adeptness than people. This may create a quite different balance between how robots make decisions and how people do using emotion and reason in tandem.

Emotion – human emotion are general states that arise in response to both internal and external events and provide both the motivation and the criteria on which decisions are made. In a robot, emerging global states could also potentially act to control decision-making. Both people, and potentially robots, can develop the capacity to explicitly recognize and control these global states (e.g. as when suppressing anger). This ability to reflect, and to cause changes in perspective and behaviour, is a kind of feedback loop that is inherently unpredictable. Not having sufficient understanding to predict how either people or robots will react under particular circumstances, creates significant uncertainty.

Imagination – much the same argument about predictability can be made about imagination. Who knows where either a person’s or a robot’s imagination may take them? Chess computers out-performed human players because of their capacity to reason in depth about the outcomes of every move, not because they used pattern-matching based on machine learning (although it seems likely that this approach will have been tried and succeeded by now). Robots can far exceed human capacities to reason through and model future states. A combination of brute force computing and heuristics to guide search, may have far-reaching consequences for a robot’s ability to model the world and predict future outcomes, and may far exceed that of people.

Faith – faith is axiomatic for people and might also be for robots. People can change their faith (especially in a religious, political or ethical sense) but more likely, when confronted with contradictory evidence or sufficient need (i.e. to align with a partner’s faith) people with either ignore the evidence or find reasons to discount it. This way can lead to multiple interpretations of the same basic axioms, in the same way as there are many religious denominations and many interpretations of key texts within these. In robots, Asimov’s three laws of robotics would equate to their faith. However, if robots used similar mechanisms as people (e.g. cognitive dissonance) to resolve conflicting beliefs, then in the same way as God’s will can be used to justify any behaviour, a robot may be able to construct a rationale for any behaviour whatever its axioms. There would be no guarantee that a robot would obey its own axiomatic laws.

Communication – The term language is better labeled ‘communication’ in order to make it more apparent that it extends to all methods by which we ‘come to know’ from sources outside ourselves. Since communication of knowledge from others is not direct experience, it is effectively taken on trust. In one sense it is a matter of faith. However, the degree of consistency across external sources and between what is communicated (i.e. that a teacher or TV will re-enforce what a parent has said etc.) and between what is communicated and what is directly observed (for example, that a person does what he says he will do) will reveal some sources as more believable than others. Also we appeal to motive as a method of assessing degree of trust. People are notoriously influenced by the norms, opinions and behaviours of their own reference groups. Robots with their potential for high bandwidth communication could, in principle, behave with the same psychology of the crowd as humans, only much more rapidly and ‘single-mindedly’. It is not difficult to see how the Dr Who image of the Borg, acting a one consciousness, could come about.

Other Ways of Knowing

It is worth considering just a few of the many other ‘ways’ of knowing’ not considered above, partly because some of these might help mitigate some of the risks of human ‘ways of knowing’ .

Science – Science has evolved methods that are deliberately designed to create impartial, robust and consistent models and explanations of the world. If we want robots to create accurate models, then an appeal to scientific method is one approach. In science, patterns are observed, hypotheses are formulated to account for these patterns, and the hypotheses are then tested as impartially as possible. Science also seeks consistency by reconciling disparate findings into coherent overall theories. While we may want robots to use scientific methods in their reasoning, we may want to ensure that robots do not perform experiments in the real world simply for the sake of making their own discoveries. An image of concentration camp scientists comes to mind. Nevertheless, in many small ways robots will need to be empirical rather than theoretical in order to operate at all.

Argument – Just like people, robots of any complexity will encounter ambiguity and inconsistencies. These will be inconsistencies between expectation and actuality, between data from one way of knowing and another (e.g. between reason and faith, or between perception and imagination etc.), or between a current state and a goal state. The mechanisms by which these inconsistencies are resolved will be crucial. The formulation of claims; the identification, gathering and marshalling of evidence; the assessment of the relevance of evidence; and the weighing of the evidence, are all processes akin to science but can cut across many ‘ways of knowing’ as an aid to decision making. Also, this approach may help provide explanations of a robot’s behaviour that would be understandable to people and thereby help bridge the gap between opaque mechanisms, such as pattern matching, and what people will accept as valid explanations.

Meditation – Meditation is a place-holder for the many ways in which altered states of consciousness can lead to new knowledge. Dreaming, for example, is another altered state that may lead to new hypotheses and models based on novel combination of elements that would not otherwise have been brought together. People certainly have these altered states of consciousness. Could there be an equivalent in the robot, and would we want robots to indulge in such extreme imaginative states where we would have no idea what they might consist of? This is not to necessarily attribute consciousness to robots, which is a separate, and probably meta-physical question.

Theory of mind – For any autonomous agent with its own beliefs and intentions, including a robot, it is crucial to its survival to have some notion of the intentions of other autonomous agents, especially when they might be a direct threat to survival. People have sophisticated but highly biased and error-prone mechanisms for modelling the intentions of others. These mechanisms are particularly alert for any sign of threat and, as a proven mechanism, tend to assume threat even when none is present. The people that did not do this, died out. Work in robotics already recognizes that, to be useful, robots have to cooperate with people and this requires some modelling of their intentions. As this last video illustrates, the modelling of others intentions is inherently complex because it is recursive.

YouTube Video, Comprehending Orders of Intentionality (for R. D. Laing), Corey Anton, September 2014, 31:31 minutes

If there is a conclusion to this analysis of ‘ways of knowing’ it is that creating intelligent, autonomous mechanisms, such as robots and AIs, will have inherently unpredictable consequences, and that, because the human operating system is so highly error-prone and subject to bias, we should not necessarily build them in our own image.

– Executive function (HOS 3)

Executive Function
Secret of Success

Executive Function in the Individual and the Organisation

Successful organisations like Google and Facebook allow their employees an opportunity to experiment and pursue their own projects. Many public sector organisations also allow their employees opportunity for personal development. Why does this work and what does it say about how organisations need to be run in a world of increasingly rapid change? What kind of executive control is appropriate for organisations in the 21st Century?

To answer this we could look at all kinds of management, organisational and accounting theory. But there is another perspective. This is to look at what psychology has revealed about the executive function (REFs 1, 2, 3) in the individual and then to map that back onto what it means in terms of the organisation. This perspective can be revealing. It highlights why organisations behave in certain ways, it can help distinguish useful and healthy behaviours from those that are ineffective, aberrant and perhaps eventually self-defeating, and it can give us a way of looking at the executive function that is grounded in an increasingly sophisticated understanding of the human condition. It can point the way to making organisations more resilient.

There are several distinct components to executive function in the individual. These develop from infancy to adulthood more or less in order. This article looks at the overall architecture of control within an organisation then goes through seven executive functions one by one, first looking at what it means in psychological terms, then mapping it onto what it might mean in terms of organisational behaviour and the functions of an executive board.

In both the individual and the organisation, executive function is self-regulation. It is ‘actions on oneself’ or, in the organisational context, the executive actions in relation to the organisation itself. When fully developed the several aspects of executive function go together to provide the capacity for self-control in a complex and changing world.

There are numerous accounts of what makes for success in both the individual (and in the organisation). Many of these emphasise one or other aspect of executive function such as self-awareness, self-direction or emotional intelligence. However, all aspects of the executive function have a part to play, and understanding executive function helps demonstrate how all these parts develop and integrate to provide the many capabilities needed for success.

The Architecture of Control

The overall architecture of control in both the individual and the organisation can be seen as a two-part system with executive function residing in the second part.

Part 1 – An Automatic System

Much of what happens in both individuals and organisations goes on without much thought or reflection.

Individuals follow their routines and habits. When everything is predictable, actions like cooking or driving can be carried out largely on ‘autopilot’, often while thinking about something entirely different. In this manner, we can operate adequately on the basis of responding to cues in the immediate environment with little conscious control or effort. This is what Kahneman in his book ‘Thinking fast and Slow’ (REF 4) calls ‘System 1’ or intuitive thinking. It deals with the here and now when everything is familiar and reasonably certain.

REF 4
YouTube Video, Kahneman: “Thinking, Fast and Slow” | Talks at Google, November 2011, 1:02 hours

Similarly, in the organisation many activities can be carried out according to it’s established procedures and practices and require no executive intervention. They may have needed executive intervention to set them up but once bedded-in they can run without further executive input unless something unexpected or out of the ordinary happens.

Part 2 – A System for Exception Handling and Taking Proactive Control

Exception Handling

This system is engaged when the automatic system needs help. In terms of Khaneman’s theory, it is ‘System 2’ thinking. It is engaged when encountering difficulty, novelty and in matters that are not in the here and now. The executive level allows ‘action at a distance’ from the here and now, and deals with circumstances that are less certain and predictable.

In the individual, when something unpredictable happens, this system seems to pop items into consciousness and then relies on a somewhat slow and labourious form of conscious processing to effect a resolution. This takes effort and resource. It takes willpower and can use up cognitive capacity. What can be done is limited by the available capacity, and focus of attention on one thing will limit the capacity to pay attention to another.

In the organisation the executive may be called in to deal with some problem or may step in when it sees something going off-track (like profits, sales, production, costs, staff-turnover etc). As with the individual, this system, is slow and labourious by contrast to the ‘business as usual’ operation. It also requires the consumption of precious resources and dealing with one situation can detract from dealing with another, perhaps causing the organisation to take it’s eye off the ball.

In practice, in a healthy individual or organisation, the automatic system and the exception handling system work together in a highly interleaved manner. They also develop together. Functions that start out as requiring exception handling, become automated over time as they become embedded.

Pro-active Control

In the individual, the pro-active element of executive function emerges in childhood. The extent of the ability to inhibit certain behaviours correlates highly with many factors in later life including academic and social competence, wealth, health and (negatively with) criminality. It seems that the developing child moves gradually from reactive control to pro-active control. (REF 5).

REF 5
YouTube Video, Integrative Science Symposium: Lifespan Development of Executive Control, July 2015, 2:10:08 hours

This is more than just being able to stop or inhibit certain behaviours. There is an extra step. This is to re-construe the world in a slightly different way and become alert to other things going on in the environment. The extra step leaves open the option to continue the behaviour, stop it or do something more subtle.

Similarly, in the organisation, spotting an undesirable behaviour, trend or process does not generally result in immediately shutting it down. There is a period of reflection, where attention may be re-focused and alternatives considered. In both organisations and individuals, this may take time. An individual may think through the potential consequences of taking particular courses of action. The organisation may do the same by embarking on investigations or sophisticated modelling and simulations to help clarify the consequences of running with different options.

A simplified model of the control and executive function is:

  • No problems – continue on autopilot
  • Problem – re-focus attention, generate and evaluate options

Also, it is notable that problem solving can go on recursively. So, if a problem is encountered with any of the sub-processes of problem solving, then that’s a new problem that is subject to the same processes in achieving resolution. Meanwhile the whole process is being recursively and externally evaluated such that if it’s not going anywhere useful, it itself can be re-considered.

7 Stages of Development of Executive Function

Seven stages of development of the executive function are described in terms of what’s going on for both the individual and the organisation. There are striking parallels.
Many of these stages have a time dimension. An infant lives in the here and now, a teenager in perhaps weeks. An adult, like an organisation, may have a time horizon of months or years. The development of executive function enables longer time horizons.

In Early Development (0 years to 5 years)

Stage 1 – Self-Awareness

In the individual, self-awareness develops in infancy (from 3 months and continues to develop for a further 10 years). The capacity to turn one’s attention away from the environment and towards ones own actions and thoughts, grows. The self-monitoring function redirects attention back on the self. An executive has developed that watches the self.

An organisation might be self-aware from the start if it has been set up with management information systems. The executives can inspect the reports and consider actions designed to affect trends they see in the data. The executives normally act within a stable framework of parameters albeit that the values on the parameters are changing. Also an organisation may grow in self-awareness by introducing new systems to provide feedback on what are deemed to be key parameters.

When (informal or formal) management information systems come into play, they can become the basis of a prevailing viewpoint on the direction of the organisation, both past and future. This is the backdrop against which executive decision-making takes place. The organisation has become to some degree self-aware and able to turn attention onto itself.

However, both the individual and the organisation operate in what Simon refers to as ‘bounded rationality’ (REF 6). Organisational self-awareness is subjective in the sense that the organisation is only aware of what it is aware of. It may not be aware of all manner of things and what it is aware of may not be representative or accurate. In this sense, the organisation mimics the individual and may be subject to the same misconceptions about the self.

For example, Baring Bank may have been blind to the extent of the damage a rogue trader could do. Kodak may have deluded itself into thinking that there would always be a market for film (as opposed to digital). In 2008, the banking industry may have been unaware of the damage it might do to itself by not containing risk. Just as likely, these organisations were aware but didn’t care or know how to react.

These are just examples of self-awareness of organisations and begs the question of who holds this awareness. Is it distributed throughout the organisation or is it held by the executive? Just as in the brain, any one neuron is ‘aware’ of the activity of other neurons it is connected to, whether they be near neighbours or in some more remote location, awareness is distributed throughout the individuals and departments in an organisation. Each department and organisational role is tasked with being informed about particular things – production, human resources, suppliers and so on. In collecting and reporting both quantitative and qualitative data about local activity, the executive is fed information from across the organisation and can build a broader awareness. However, just as the brain can be deceived by it’s senses or selective and biased in its interpretation, the uncritical executive can also be led astray.

Stage 2 – Self-Restraint

Self-restraint develops In the individual between the ages of 3 and 5 years. This is the ability for a child to stop him or herself doing something that they would otherwise do automatically (like taking a sweet). It is inhibition of action. Children between 3 and 5 years will put their hands over their mouths to stop themselves saying something. In time this ‘executive inhibition’ can be done internally but it takes effort. It draws down on a limited resource.

In the organisation there are several mechanisms for self-restraint. Budgets act as inhibitors by containing costs in parts of the organisation and overall. Also, organisational policies, procedures, standards and guidelines are often designed to inhibit behaviours other than those already approved. The development of procedures is often motivated by ‘error’ – something has gone wrong and the organisation tries to make sure it doesn’t happen again. Procedures, new or just changing, often meet some resistance and it takes effort or resource to overcome it. Once bedded in, however, they can be executed more cheaply. The operation of restraint has become automatic. It has moved from the proactive and exception handling control system to the routine and automatic control system.

Stage 3 – Imagery and rapid brain development

In the individual imagery is ‘the mind’s eye’ or ‘a theatre in your mind’. It is the ability to resurrect (visual and other) images from the past (together with accompanying emotions) to deal with the present. In the child, imagery develops between 3 and 5 years. This is mainly imagery of situations represented in all the salient senses – visual, auditory, tactile, taste and smell – whatever was relevant at the time. The imagery may be stored along with how you feel about it, good or bad (to some degree). Pattern-matching triggers memories and resurrects relevant imagery from the past to act as a guide or a map that can be used in the here and now.

The developing brain at this stage consumes 60% of the glucose consumed in food and is creating new connections between neurones at a rapid rate. Although the visual systems in the brain can be fully wired up from the age of one, other sensory modalities take longer. At some stage a tipping point is reached when infrequently used connections are purged. This developmental progression is thought to facilitate innovation and hypothesis testing about the environment up to the point where consolidation on viable interpretations set in. The young mind mimics the progression of science in exploration before consolidation into useful knowledge that can drive applications.

In the organisation, the memories of staff and the management of files, file sharing, databases and information systems is its ‘working memory’. These systems are largely designed with retrieval in mind. Although, the data captured is not inherently what you would call image-evoking, it does perform the same function of retrieving memories (records, documents, anecdotes) that help guide action in the here and now. Envisioning activities, prototyping, simulation and modelling activities in the organisation, parallel the ‘theatre of the mind’. They are part of the organisations imaginative activity, where ideas can be tried out before they are fully implemented (and incur the full costs and consequences of acting on the world outside the organisation).

Stage 3a – Theory of Mind

There is another important stage that appears to develop between the ages of 3 and 5 years, that tends not to be emphasised in the mainstream literature on executive function. This is the so-called ‘theory of mind’ (REF6a) – the ability of a person to model what another person is thinking and feeling. Experiments with children show that a three year old expects everybody else to know what they themselves know, while by 5 years a child understands that other people can have different beliefs from themselves. If, for example, the content of a chocolate box is replaced with, say crayons, in front of a three year old, they will think that somebody later coming into the room will expect to find crayons in the box rather than chocolates. They are unable to differentiate between their own knowledge and the knowledge of others.

REF 6a
YouTube Video, Robert Seyfarth: Theory of Mind, Richard Dawkins Foundation for Reason & Science, May 2010, 3:36 minutes

Theory of mind may not be addressed in mainstream accounts of executive function because it is thought of as a social skill rather than a fundamental information processing capability, but I think it should be thought of as a key part of executive function because it is a base on which later executive functions develop. The multiple voices that develop in private speech, for example, are akin to the playing out in the mind of multiple belief systems and theory of mind must also impact on management of ones own emotions and motivations. In fact, the implications of theory of mind are so significant that it has generated its own large literature. Autism and Asperger’s Spectrum disorders increasingly reference both deficiencies in executive function and in theory of mind, adding further support to the argument that theory of mind should be seen as an aspect of executive function.

Research at the Max Planck Institute suggests that the maturation of fibres of a brain structure called the arcuate fascicle, between the ages of three and four years, establishes a connection between (1) a region at the back of the temporal lobe that supports adults thinking about others and their thoughts and (2) a region in the frontal lobe that is involved in keeping things at different levels of abstraction.

REF 6b

In the organisation, ‘theory of mind’ is akin to understanding your competitors and your markets. If an organisation’s theory is accurate then it will be better able to anticipate the consequences of events, both those that it control and those that are external (e.g. government legislation and changes in market conditions). For example, if an organisation changes the price of one of its products, it would be useful to be able to predict what its customers and competitors would think about this and how they are likely to respond. A good businessman, like a good car salesman, may have an instinct about how customers will respond and may be able to construct a more or less complicated strategy that will drive the behaviours of others in particular ways.

From 5 Years

Stage 4 – Private Speech

In the individual, at 3 years old everything is public. Children talk to themselves about the world. Listening to their own speech is a mechanism facilitating reflection and self-control. Between 3 and 5 years vocal actions and accompanying facial expressions become suppressed and the voice becomes internalized as a silent mechanisms of self-control.

Artificial intelligence is now being recruited to re-create the kind of dialogue we have with our inner voices.

However, even as adults, the nuances of facial expression leak information about what is going on in the mind, but most adults learn to distinguish between situations in which this is useful and those in which it presents some danger. Also, they can learn how to dissociate what is going on in the mind from what leaks out in the face and body language, thereby conferring the ability to deceive. (REF 7)

In the organisation, executives are only too aware that they cannot air all of their thoughts in public. Executives are ultra-careful about what they communicate, to whom and how, or they soon learn. Board meetings are often closed and communications can be deliberately targeted, sometime with the help of a communications or PR department. Wise executives rarely blurt out the first thing that comes into their heads. They inhibit that tendency and use their own thoughts to first control their own behaviour. They exercise self-control. Some private speech ends up in the boardroom, especially the closed sessions, while the public speech is crafted by the PR department. Just as in the individual this can be crafted to deceive or mislead, but also, just as in the individual, the real danger comes when the executive starts to believe its own deceptions.

Stage 5 – Management of own emotions

The individual, by resurrecting images of the past, can ‘control’ his or her own emotional states in order to be able to socialize more effectively and not drive other people away. An individual can act to put themselves in a better frame of mind, not make important decision while angry, and otherwise act to exert some control over their own emotional state.

Daniel Goleman (REF 8) in his book ‘Emotional Intelligence’ identifies 4 aspects of emotional intelligence – (1) Self Awareness (2) Self-Management (3) Empathy and (4) Relationship Management. The first two of these are regarded as key executive functions whilst empathy and relationship management extend executive function into the social sphere that do not fully develop until adulthood.

REF 8
YouTube Video, Daniel Goleman Introduces Emotional Intelligence, April 2012, 5:31 minutes

Can organisations be said to have emotions? The answer is ‘yes’. Announcing profits, losses, redundancies, being given awards or a bad press can have emotional repercussions throughout the organisation. Sustained ‘moods’ can have implications for the organisation culture. Some organisations have enthusiasm and optimism while others have low morale and become depressed and dysfunctional. Some organisations feel threatened, get anxious and show some of the common human defence mechanisms such as denial, over-compensation, projection and compartmentalisation (REF 9).

REF 9
Article, 15 Common Defense Mechanisms, John M. Grohol, Psy.D.
http://psychcentral.com/lib/15-common-defense-mechanisms/

The organisational memory of emotional events in the past (both traumatic and elating) can help to manage a current situation but often relies on there still being people engaged that remember the past. Most executives are only too aware of the relationship between the mood and culture of an organisation and its performance, and act to manage the mood. Even when times are hard they convey a positive message and vision that helps take the organisation forward. However, an unrealistic representation, or a glossing over of current circumstances, risks losing the trust of the people that are the key to future success.

Stage 6 – Management of own motivations

In the individual, this is self-motivation or self-determination. Management of your own motivations frees the individual from thinking and acting in ways that have been learnt, either through practice in response to circumstances or by copying others. It opens new doors. You no longer have to be driven by habits or others expectations. You can think for yourself, determine your own goals, prioritise them as you think fit and work towards them in any way that you like.

Imagery has already developed to allow external consequences to be substituted by mental representation. Motivations can thereby be created in relation to events that are distant in space and time, and these can be reasoned about and managed without recourse to acting on the outside world.

In the organisation: Organisations specialise in the management of motivation. In particular they manage motivations with respect to profit (or at least self sustainability) but this is achieved with reference to the organisation’s mission. Many companies will have a list of strategic goals or intentions, and although profit often comes high on the list, there are others such as customer and staff satisfaction. Often separate departments take charge of these different motivations but eventually it is the executive that must coordinate them. At worst it must suppress conflicts. At best it provides orchestration, aligning motivations so that parts of the organisation support each other.

Daniel Pink in his book ‘Drive’ (REF 10) describes recent studies on how organisational incentives affect employee motivation. For routine tasks that can be performed on ‘auto-pilot’ (system 1 thinking) monitory incentives seem to work well as a means of keeping people on task and increasing performance. However, and running counter to previous views, it seems that financial incentives either do not work or actually impair performance when the work involves higher level executive functions such as reasoning and problem solving. The more effective incentives for these types of tasks are: autonomy, mastery and purpose. Autonomy means allowing employees to have the freedom to achieve goals in a manner of their own choosing, rather than having the method defined and prescribed. Mastery means giving the employee the freedom and resources to develop their own skills to a high standard, helping engender a greater degree of self-worth. Purpose refers to a socially useful purpose beyond that of the individual. It means joining with others to achieve something great, that the individual could not have achieved alone. Pink argues that the 21st Century worker must be incentivised in this way or they will not be sufficiently agile , resourceful, flexible and resilient to cope with the rapidly changing demands of a modern global economy.

Stage 7 – Internalised Play

In the individual, the last manifestation of executive function is internalised play (REF 11). Internal play involves self-awareness and analysis, imagery, synthesis, planning, emotional and motivational control, and problem solving. It builds on all the other executive functions to allow us to take apart any object of our thoughts and re-construct them in the mind, in novel ways, to meet the needs of the moment.

REF 11
YouTube Video, Learning Through Play: Developing Children’s Executive Function, Center on the Developing Child at Harvard University, September 2015, 27 seconds

In the organisation: Organisations that are big and profitable enough, make room for a lot of internal play and experimentation, only some of which will lead anywhere. Play itself allows the organisation to exercise its muscles, fine tune its processes and see where ideas might lead without heavy financial commitment.

Several references are provided below to elaborate on this and to show how play is a necessary ingredient in the development of the highest levels of executive function.

Implications for Organisational Development

Self-Awareness: Without self-awareness there is no self-control, but equally damaging is an inaccurate or biased self-awareness. Key Process Indicators (KPIs) and other management information systems can provide self-awareness but in the same way that an individual can become pre-occupied with their own inaccurate perception of themselves, an organisation can become equally distracted by KPIs that are easy to measure but are not closely aligned to its mission and strategy. It is only too easy to be deceived by the apparent objectivity of KPIs, especially when it is in the interests of different parts of the organisation to supply data that it knows the executive wants to see. In the same way that individuals tend to select the information that confirms their prejudices, an organisation can be similarly ‘blind’ to information it feels uncomfortable with.

Self-Restraint: An individual without self-restraint is often impulsive, easily distracted, lacks focus and fails to finish tasks. Too much restraint, by contrast, makes the individual inflexible and fixated. Organisations without self-restraint often pursue short-term goals at the expense of longer-term profitability. They are unable to defer gratification. By contrast, some organisations the have a tendency to over-control and tie themselves up in their own bureaucracy. Over time more and more procedure is put into place, often to correct errors of the past, until it is so rigid that it cannot respond to change. This is one reason that organisations often continuously re-structure and why some organisations seem to pulsate as control alternates between being drawn into the centre and distributed to autonomous operating units. Each process seems to run away with itself then needs to be reigned in again. The best organisations, rather than control, simply provide services to their management making it easy to carry out the functions that are central to its strategy, and more difficult to do anything else.

Imagery: The capacity to create, store and retrieve information is key to the individual in their personal development. Without the capability to learn from the past and retrieve that information when relevant an individual would act like an amnesic. An organisation without a memory of the past is similarly disoriented, and will stumble about without an understanding of what works and what doesn’t. Furthermore, without memory it is impossible to imagine what could be. Images of the past are the building blocks on which futures are built, often combining elements of the past in new ways to create novel solutions.

Theory of Mind: Understanding how customers and markets will react to events, including those events an organisation has control over, is critical in navigating and organisation through a constantly changing world. An organisation, say a government, that fails to anticipate a negative reaction to a new policy, law or budget change may find itself having to backtrack and even apologise. This is perceived as a weakness, precisely because it demonstrates that the organisation has an inadequate theory about other players. In politics in particular, it shows incompetence because politics is all about the anticipation and management of others’ reactions.

Private Speech: Private speech is more than just suppressing what is shown in public. It is the capacity to create internal dialogue and debate, to model and speculate on possible consequences of actions that have not yet been performed. The evaluation of actions before they are performed is essential to good decision making in both the individual and the organisation. Investment decisions benefit greatly from hearing a range of voices, from both within and outside the organisation, before they are acted on.

Management of Emotions: Emotions are at the route of most decision-making because they impact both an individual’s and an organisation’s priorities. The prevailing ethos of an organisation and how it affects the way staff feel, can be critical to the smooth functioning of the organisation. Some organisations have a ‘blame’ culture and, all factors being equal, any spontaneous activity on behalf of employees is suppressed. Others encourage free-thinking and innovation. How many organisations monitor these cultural and emotional factors and manage them as standing agenda items? Even when managed, most organisations are ineffective in the control of the prevailing emotional ethos and their interventions to control can easily backfire, especially if they look manipulative.

Management of Motivations: Like other functions ‘management of motivations’ can be done over-zealously or in too relaxed a manner. Self-determination is an asset so long as it does not fly in the face of circumstances. Motivations and intentions have to compromise with circumstance. The market has to be ready for your brilliant idea. Having said that, switching motivations has a cost. Even introducing a new service is expensive, let alone an entire change of strategy. Balancing the benefits of sticking to your guns with the cost of being flexible is a necessary skill. Organisations that manage to successfully grow organically achieve this balance.

Play: An individual cannot be fully functional without the opportunity to integrate all its mechanisms of executive control around the activity of play. Play allows experimentation and innovation in a safe environment, away from the dangers of the real world. Similarly, the organisation cannot be said to be fully functional without some room to play. The organisational practices of accounting for everything, monitoring every key performance indicator or extorting every last drop of employee or shareholder value, leads to organisations that are essentially reactive and immature. They are unpractised at thinking deeply at all organisational levels, and therefore lack resilience and the ability to adapt smoothly to changing circumstances. Like the individual that has failed to develop a wide range of coping strategies, they may lurch from crisis to crisis. Essentially, any change in circumstances can result in them becoming ‘out of control’.

– Managing demands (HOS 2)

How we manage the demands on us has been a pre-occupation since the day I came to the realisation that a lot of what runs through my own mind can be explained in terms of what psychologists call the management of ‘cognitive load’ or ‘mental workload’. We all, to some extent, ‘manage’ what we think about, but we rarely reflect on exactly how we do it.

Sometimes there are so many things that need to be thought about (and acted upon) that it is overwhelming, and some management of attention is needed, just to get through the day and maintain performance. If you need convincing that workload can affect performance then consider the research on distractions when driving. (A more comprehensive analysis on ‘the distracted mind’ can be found at the end of this posting).

YouTube Video, The distracted mind, TEDPartners, December 2013, 1:39 minutes

At other times you find yourself twiddling your thumbs, as if waiting for something to happen, or a thought to occur that will trigger action. We sometimes cease to be in the grip of circumstances and our minds can run free.

If you keep asking the question ‘why?’ about anything that you do, you eventually arrive at a small number of answers. If we leave aside metaphysical answers like ‘because it is the will of God’ for the moment, these are generally ‘to keep safe’ or ‘to be efficient’. On the way to these fundamental, and intimately related to them, is ‘to optimize cognitive load’. Not to do so, compromises both safety and efficiency.

To be overwhelmed with the need to act and, therefore, the thinking this necessitates in the evaluation of choices that are the precursors of action, leads to anxiety and anxiety interferes with the capacity to make good choices. To be under-whelmed leads to boredom and lethargy, a lack of caring about choice and the tendency to procrastinate.

It seems that to perform well we need an optimal level of arousal or stimulation.

Youtube Video, Performance and Arousal – Part 1of 3: Inverted U Hypothesis, HumberEDU, January 2015, 5:05 minutes

In the longer term, to be ‘psychologically healthy’ we need optimal levels of arousal ‘on average’ over a period of time.

Being constantly overwhelmed leads from stress, to anxiety and onwards to depression. It can even lead to an early death.

TED Video, The science of cells that never get old’ – Elizabeth Blackburn, TED, April 2017, 18:46 minutes

Being constantly underwhelmed also leads to depression via a different route. How much load we can take depends on our resources – both cognitive and otherwise. We can draw on reserves of energy and a stock of strategies, such as prioritizing, for managing mental workload. If the demands on us are too great and we have some external resources, like somebody else that can provide advice or direction, or the money to pay for it, then we can use those to lessen the load. Whenever we draw on our own capacities and resources we can both enhance and deplete them. Like exercising a muscle, regular and moderate use can strengthen but prolonged and heavy use will tire or deplete them. When we draw on external resources, like money or favours, their use tends to deplete them.

Measurement of Load

So how can we measure the amount of load a person is carrying. This is going to be tricky as some people have more resource and capacity (both internal and external) than others, so observing their activity may not be a very accurate measure of load. If you are very practiced or skilled at something it is much easier to do than if you are learning it for the first time. Also, some people are simply less bothered about whether they achieve what they have to do (or want to do) than others. Even the same person can ‘re-calibrate’, so for example, if pressure of work is causing stress, they can re-assess how much it matters that they get the job done. Some capacities replenish with rest, so something may be easy at one time but harder, say at the end of a long day.

In fact, there are so many factors, some interacting, that any measure, say of stress, through looking at the chemicals in the blood or the amount of sweating on the skin is difficult to attribute to a particular cause.

The capacity of our thinking processes is limited. We can really only focus on one difficult task at once. We even stop doing whatever we were doing (even an automatic task like walking) when formulating the response to a difficult question.

BBC Radio 4, The Human Zoo, Series 1 Episode 1, First Broadcast about 2014, 28 minutes
http://www.bbc.co.uk/programmes/b01r0gj4

We can use our thinking capacity to further our intentions but we so often get caught up in the distractions of everyday life that none is left for addressing the important issues.

The Personal Agenda

Another way of looking at it is to consider it from the point of view of each person’s agenda and how they deal with it. This is as if you ask a person to write down a ‘to do’ list which has everything they could think of on it. We all do this from time to time, especially when there is too much going on in our heads and we need to set everything out and see what is important.
I will construct such a list for myself now:


  • Continue with what I am writing
  • Get ready for my friend who is coming for coffee
  • Figure out how to pay my bills this month
  • Check with my son that he has chosen his GCSE options
  • Tell my other friends what time I will meet them tonight
  • Check that everything is OK with my house at home (as I am away at the moment)

Each of these agenda items is a demand on my attention. It is as if each intention competes with the others to get my focus. They each shout their demands, and whichever is shouting loudest at the time, wins. Maybe not for long. If I realise that I can put something off until later, it can quickly be dismissed and slip back down the agenda.

But the above list is a particular type that is just concerned with a few short-term goals – it’s the things that are on my mind today. I could add:


  • Progress my project to landscape the garden
  • Think through how to handle a difficult relationship

Or some even longer term, more aspirational and less defined goals

  • Work out how I will help starving children in Africa
  • Maintain and enhance my wellbeing

The extended agenda still misses out a whole host of things that ‘go without saying’ such as looking after my children, activities that are defined during the course of going to work, making sure I eat and sleep regularly, and all tasks that are performed on ‘autopilot’ such as changing gear when driving. It also misses out things that I would do ‘if the opportunity arose’ but which I do not explicitly set out to do.

What characterizes the items that form the agenda? They are all intentions of one sort or another but they can be classified in various ways. Many concern obligations – either to family, friends, employers or society more generally. Some are entirely self-motivated. Some have significant consequences if they are not acted upon, especially the obligations, whereas others matter less. Some need immediate attention while others are not so time critical. Some are easy to implement while others require some considerable training, preparation or the sustained execution of a detailed plan. Some are one-offs while others are recurring, either regularly or in response to circumstances. This variation tends to mask the common characteristic that they are all drivers of thought and behaviour.

Intentions bridge between and include both motives and goals. Generally we can think of motives as the inputs and goals as the outputs (although either can be either). Both the motives and the goals of an intention can be vague. In fact, an intention can exist without you knowing either why or what it is to achieve. You can copy somebody else’s intention in ignorance of motive and goal. In the sense of intention as only a pre-disposition to act, you need not be aware of an intention. Often you don’t know how you will act until the occasion demands.

Agenda Management

Given that there are perhaps hundreds or even thousands of intentions large or small, all subsisting in the same individual, what determines what a person does at any particular point in time. It all depends on priority and circumstance. Priority will push items to the top of the list and circumstance often determines when and how they drive thought and behaviour.

Priority

Priority itself is not a simple idea. There are many factors affecting priority including emotion, certainty of outcome and timing. These factors tend to interact. I may feel strongly that I must help starving children in Africa and although I know that every moment I delay may mean a life lost, I cannot be certain that my actions will make a difference or that I may think of a more effective plan at a later time. When I have just seen a programme on TV about Africa I may be highly motivated, but a day later, I may have become distracted by the need to deal with what now appear to be more urgent issues where I can be more certain of the outcome.

Priority and Emotion

It is as if my emotional reaction to the current content of my experience is constantly jiggling the priorities on my agenda of intentions. As the time approaches for my friend to arrive I start to feel increasingly uncomfortable that I have not cleared up. Events may occur that ‘grab’ my attention and shoot priorities to the top of the agenda. If I am surprised by something I turn my attention to it. Similarly, if I feel threatened. Whereas, when I am relaxed my mind can wander to matters inside my head – perhaps my personal agenda. If I am depressed my overall capacity to attend to and progress intentions is reduced.

Emotions steer our attention. They determine priority. Attention is focused on the highest priority item. Emotion, priority, and attentions are intimately related. Changing emotions continuously wash across intentions, reordering their priority. They modulate the priorities of the intentions of the now.

Emotion provides the motive force that drives attention to whatever it is that you are attending to. If you are working out something complicated in your head, it is the emotion associated with wanting to know the answer that provides the motive force to turn the cogs. This applies even when the intention is to think through something rationally. When in the flow of rational thought (say in doing a mental arithmetic problem) it is emotion that motivates it.

There is a host of literature on emotional memory (i.e. how emotions, especially traumatic ones, are laid down in memory). There is also a large literature on how memories may be re-constructed, often inaccurately, rather than retrieved. The following illustrates both emotional memory of traumatic events and the frequent inaccuracies of re-construction:

TED Video, Emotional Memory: Shawn Hayes at TEDxSacramento 2012, TEDx Talks, March 2013, 8:10 minutes

It is well established that the context in which a memory is laid down effects the circumstances in which the memory is retried. For example, being in a particular place, or experiencing a particular smell or taste may trigger the retrieval of memories specific to the place and smell. The context supplies the cue or key to ’unlocking’ the memory. However, there is comparatively little literature on how emotions trigger memories although there has been research on ‘mood-dependent memory’ (MDM) e.g.

Eric Eich, Dawn Macaulay, and Lee Ryan (1994), Mood Dependent Memory for Events of the Personal Past, Journal of Experimental Psychology: General 1994, Vol. 123, No. 2, 201-215

http://www.communicationcache.com/uploads/1/0/8/8/10887248/mood_dependent_memory_for_events_of_the_personal_past.pdf

It seems plausible that emotions act as keys or triggers that prime particular memories, thoughts and intentions. In fact, the research indicates that mood dependent memory is more salient in relation to internal phenomena (e.g. thoughts) than external ones (such as place). Sadness steers my attention to sad things and the intentions I associate with the object(s) of my sadness. Indifference will steer my attention away from whatever I am indifferent about and release attention for something more emotionally charged. Love and hate might equally steer attention to its objects. Injustice will steer attention to ascertaining blame. The task of identifying who or what to blame can be as much an intention as any other.

Priority and Time – The Significance of Now

Intentions formulated and executable in ‘the now’, assume greater priority than those formulated in the past, or those that may only have consequences in the future.

The now is of special significance because that is where attention is focused. Past intentions slip down the list like old messages in an email inbox. You focus on the latest delivery – the now.

The special significance of ‘the now’ is increasingly recognised, not just as a fact of life but as something to become increasingly conscious of and savoured.

‪Youtube Video, The Enjoyment of Being with Eckhart Tolle author of THE POWER OF NOW, New World Library, July 2013, 4:35 minutes

Indeed the whole movement of mindfulness, with its focus on ‘the now’ and conscious experience, has grown up as approach to the management of stress and the development of mental strategies.

‪Youtube Video, The Science of Mindfulness, Professor Mark Williams, OxfordMindfulness, December 2011, 3:34 minutes

Priority and Time in Agenda Management

If I am angry now then my propensity will be high to act on that anger now if I am able to. Tomorrow I will have cooled off and other intentions will have assumed priority. Tomorrow I may not have ready access to the object of my anger. On the other hand, if tomorrow an opportunity arises by chance (without me having created it), then perhaps I will seize it and act on the anger then. As in crime, we are driven by the motive, the means and the opportunity.

Many intentions recur – the intentions to eat, drink, sleep, and seek social interaction all have a cyclical pattern and act to maintain a steady state or a state that falls within certain boundaries (homeostasis). It may be that you need to revive an old intention whether or not it is cyclically recurring. Revival of an intention pushes it back up the list (towards the now) and when some homeostatic system (like hunger and eating) get out of balance a recurring intention is pushed back up the list.

Intentions that impact the near future also take priority over intentions that affect the far future. So, it is easier to make a cup of tea than sit down and write your will (except when death is in the near future). We exponentially discount the future. 1 minute, 1 hour and 1 day, 1 week, 1 month, 1 season and 1 year are equally far apart. What happens in the next minute is as important as what will happen in the next year.

Intentions Interact

However, from the point of view of establishing the principles of a control mechanism that determines our actions at any point there are other complications and considerations. Often our intentions are incompatible or compete with each other. I cannot vent my anger and fulfil an intention not to hurt anybody. I cannot eat and stay thin. I cannot both go to work tomorrow and stay home to look after my sick child. Therefore, some intentions inhibit others leading to a further jiggling of the priorities.

Prioritising what is Easy

A major determinant of what we actually do is what is easiest to do. So actions that are well learned or matters of habit get done without a second thought but intentions that are complicated or difficult to achieve are constantly pushed down the stack, however important they are. Easy actions consume less resource. If they are sufficiently difficult and also sufficiently important we become pre-occupied by thinking about them but are unable to act.

Daniel Kahneman in his book ‘Thinking Fast and Slow’ sets out much of the experimental evidence that shows how in thought we tend towards the easy options.

How often do we get up in the morning with the firm resolve to do a particular thing and then become distracted during the day by what seem to be more immediate demands or attractive alternatives? It is as if our intentions are being constantly pushed around by circumstances and our reactions to them and all that gets done are the easy things – where by chance the motive, the means, and the opportunity all fortuitously concur in time.

Staying on task is difficult. It requires a single-minded focus of attention and a resistance to distraction. It is sometimes said that ‘focus’ is what differentiates successful people from others, and while that may be true in the achievement of a particular goal, it is at the expense of paying attention to other competing intentions.

Implications for The Human Operating System

The above account demonstrates how as people we interleave multiple tasks in real time, partly in response to what is going on around us and partly in response to our internal agenda items. We do this with limited resources, depleting and restoring capacities as we go. What differentiates us from computers is the way in which priorities are continuously and globally changing such that attention is re-directed in real time to high priority items (such as threats and the unexpected). Part of this is in response to our ability to retrieve relevant memories cued by the external world and our internal states, reflect on (and inhibit) our own thinking and thinking processes and to run through and evaluate mental simulations of possible futures.

Summary


  • In order to perform effectively we need to manage the demands on us
  • Having too much, or too little, to do and think about can lead to stress in the short term and depression, if it goes on for too long.
  • We have limited resources and capacities which can become depleted but that can also be restored (e.g. with rest)
  • Measuring the amount of load a person is under is not simple as people have different resources, abilities and capacities
  • Whether or not we write it down or say it, we all have an implicit list of intentions
  • We prioritise the items on this list in a variety of ways
  • Circumstances, our emotional reactions and timing are all crucial factors in determining priority
  • We also tend to prioritise things that are easy to do (i.e. do not use up effort, time or other resources)
  • Being able to manage priorities and interleaving our intentions in response to circumstances and opportunity, is a key aspect of the human operating system

This Blog Post: ‘Human Operating System 2 – Managing Demands’ introduces how we deal with the complex web of intentions (our own and those externally imposed) that form part of our complex daily lives

Next Up: ‘Policy Regulates Behaviour’ shows that not all intentions are equal. Some intentions regulate others, in both the individual and society.

– It’s like this

We are all deluded. And for the most part we don’t know it. We often feel as though we have control over our own decisions and destiny, but how true is it?  It’s a bit like what US Secretary of Defence, Donald Rumsfeld, famously said in February 2002 about the ‘known knowns’, the ‘known unknowns’ and the ‘unknown unknowns’.

The significance for ROBOT ETHICS: If people can only act on the basis of what they know, then it is easy to see the implications for artificial Autonomous Intelligent Agents (A/ISs) like robots, that ‘know’ so much less. They may act with the same confidence as people, who have a bias to thinking that what they know and their interpretation of the world, is the only way to see it. Understanding the ‘goggles’ through which people see the world, how they learn, how they classify, how they form concepts and how they validate and communicate knowledge is fundamental to embedding ethical self-regulation into A/ISs.

 


How can a brain that is deluded even get an inkling that it is?  For the most part, the individual finds it very difficult.  Interestingly, it is often those who are most confident that they are right who are most wrong (and dangerously, who we most trust). The 2002 Nobel Prize winner, Daniel Kahneman has spent a lifetime studying the systematic biases in our thinking.  Here is what he says about confidence:

Youtube video, Daniel Kahneman: The Trouble with Confidence, Big Think, February 2012, 2:56 minutes

The fact is, that when it comes to our own interpretations of the world, there is very little that either you or I can absolutely know as demonstrated by René Descartes in 1637It has long been know that we have deficiencies in our abilities to understand and interpret the world, and indeed, it can be argued that the whole system of education is motivated by the need to help individuals make more informed and more rational decisions (although it can be equally argued that education and training in particular, is a sausage factory in the service of employers whose interests may not align with those of the individual).


 

The significance for ROBOT ETHICS: Whilst people may have some idea that there are things they do not know, this is generally untrue of most computer programs. Young children start to develop ethical ideas (e.g. a sense of fairness) from an early age. Then it takes years of schooling and good parenting to get to the point where, as an adult, the law assumes you have full responsibility for your actions. This highlights the huge gap between an adult human’s understanding of ethics and what A/ISs are likely to understand for the foreseeable future.

 


First Principles

The debate about whether we should act by reason or by our intuitions and emotions is not new. The classic work on this is Kant’s ‘Critique of Pure Reason’ published in 1781. This is a masterpiece of epistemological analysis covering science, mathematics, the psychology of mind and belief based on faith and emotion. Kant distinguishes between truth by definition, truth by inference and truth by faith, setting out the main strands of debate for centuries to come. Here is a short, clear presentation of this work.

Beliefs

From an individual’s point of view, by a process of cross validation between different sources of evidence (people we trust,  the media and society generally, our own reasoned thinking, sometimes scientific research and our feelings), we are continuously challenged to construct a consistent view about the world and about ourselves. We feel a need to create at least some kind of semi-coherent account. It’s a primary mechanism of reducing anxiety.  It keeps us orientated and safe. We need to account for it personally, and in this sense we are all ‘personal’ scientists, sifting the evidence and coming to our own conclusions.  We also need to account for it as a society, which is why we engage in science and research to build a robust body of knowledge to guide us.

George Kelly, in 1955, set out ‘personal construct theory’ to describe this from the perspective of the individual – see, for example this straight-forward account of constructivism which also, interestingly, proposes how to reconcile it with Christianity – a belief system based on an entirely different premise, methodology and pedigree):

 

But for the most part there are inconsistencies – between what we thought would happen and what actually did happen, between how we felt and how we thought, between how we thought and what we did, between how we thought somebody would react and how they did react, between our theories about the world and the evidence. Some of the time things are pretty well what we expect but almost as frequently, things don’t hang together, they just don’t add up.   This drives us on a continuous search for patterns and consistency.  We need to make sense of it all:

Youtube Video, Cognitive dissonance (Dissonant & Justified), Brad Wray, April 2011,4:31 minutes

 

But it turns out that really, as Kahneman demonstrates, we are not particularly good scientists after all.  Yes, we have to grapple with the problems of interpreting evidence.  Yes, we have to try and understand the world in order to reduce our own anxieties and make it a safer place.  But, no, we do not do this particularly systematically or rationally.  We are lazy and we are also as much artists as we are scientists. In fact, what we are is ‘story tellers’. We make up stories about how the world works – for ourselves and for others.


 

The significance for ROBOT ETHICS: The implications for A/ISs is that they must learn to see the world in a manner that is similar (or at least understandable) to the people around them. Also, they must have mechanisms to deal with ambiguous inputs and uncertain knowledge, because not much is straightforward when it comes to processing at the abstract level of ethics. Dealing with contradictory evidence by denial, forgetting and ignoring, as people often do, may not be the way we would like A/ISs to deal with ethical issues.

 


Stories

Sifting evidence is not the only way that we come to ‘know’. There is another method that, in many ways, is a lot more efficient and used just as often. This is to believe what somebody else says. So instead of having to understand and reconcile all the evidence yourself you can, as it were, delegate the responsibility to somebody you trust. This could be an expert, or a friend, or a God. After all, what does it matter whether what you (or anybody else) believe is true or not, so long as your needs are being met. If somebody (or something) repeatedly comes up with the goods, you learn to trust them and when you trust, you can breathe a sigh of relief – you no longer have to make the effort to evaluate the evidence yourself. The source of information is often just as important as the information itself. Despite the inconsistencies we believe the stories of those we trust, and if others trust us, they believe our stories.

Stories provide the explanations for what has happened and stories help us understand and predict what will happen.  Our anxiety is most relieved by ‘a good story’. And while the story needs to have some resemblance to the evidence, and like in court can be challenged and cross-examined, what seems to matter most is that it is a ‘good’ story.  And to be a ‘good’ story it must be interesting, revealing, surprising and challenging.  Its consistency is just one factor.  In fact, there can be many different stories, or accounts, of precisely the same incident or event – each account from a different perspective; interpreting, weighing and presenting the evidence from a different viewpoint or through a different value system.  The ‘truth’ is not just how well the story accounts for the evidence but is also to do with a correspondence between the interpretive framework of the listener and that of the teller:

YouTube Video, The danger of a single story | Chimamanda Ngozi Adichie, TED, October 2009, 19:16 minutes

Both as individuals and as societies, we often deny, gloss over and suppress the inconsistencies.  They can be conveniently forgotten or repressed long enough for something else to demand our attention and pre-occupy us.  But also sometimes, for the sake of a ‘better’ story (often one that better reflects the biases in our own value system), the inconsistencies and the evidence about ourselves and the human condition fight back.  Inconsistencies can re-emerge to create nagging doubts, and over time we start to wonder – is our story really true?


 

The significance for ROBOT ETHICS:Just like people, A/ISs will have to learn who to trust, identify and resolve inconsistencies in belief, and how to construct a variety of accounts of the world and their own decision making processes in order to explain themselves and generally communicate in forms that are understandable to people. Like in human dialogue, these accounts will need to bring out certain facets of it’s own beliefs, and afford certain interpretations, depending on the intent of the A/IS and taking into account a knowledge of the person or people it is in dialogue with. Unlike, in human dialogue, the intent of the A/IS must be to enhance the wellbeing of the people it serves (except when their intent is malicious with respect to other people), and to communicate transparently with this intent in mind.

 


Some Epistemological Assumptions

In these blog postings, I try not to take for granted any particular story about how we are and how we relate to each other? What really lies behind our motivations, decisions and choices?  Is it the story that classical economists tell us about rational people in a world of perfect information?  Is it the story neuroscientists tell us about how the brain works?  Is it the story about the constant struggle between the id and the super-ego told to us by Freud?  Is it the story that the advertising industry tell us about what we need for a more fulfilled life?  Or is it the story that cognitive psychologists tell us about how we process information?  Which account tells the best story?  Can these different accounts be reconciled?

The epistemological view taken in this blog is eclectic, constructivist and pragmatic. As we interact with the world, we each individually experience patterns, receive feedback, make distinctions, learn to reflect, and make and test hypotheses. The distinctions we make, become the default constructs through which we interpret the world and the labels we use to analyse, describe, reason about and communicate. Our beliefs are propositions expressed in terms of these learned distinctions and are validated via a variety of mechanisms, that themselves develop over time and can change in response to circumstances.

We are confronted with a constant stream of contradictions between ‘evidence’ obtained from different sources – from our senses, from other people, our feelings, our reasoning and so on. These surprise us as they conflict with default interpretations. When the contradictions matter, (e.g. when they are glaringly obvious, interfere with our intent, or create dilemmas with respect to some decision), we are motivated to achieve consistency. This we call ‘making sense of the world’, ‘seeking meaning’ or ‘agreeing’ (in the case of establishing consistency with others). We use many different mechanisms for dealing with inconsistencies – including testing hypotheses, reasoning, intuition and emotion, ignoring and denying.

In our own reflections and in interactions with others, we are constantly constructing mini-belief systems (i.e. stories that help orientate, predict and explain to ourselves and others). These mini-belief systems are shaped and modulated by our values (i.e. beliefs about what is good and bad) and are generally constructed as mechanisms for achieving our current intentions and future intentions. These in turn affect how we act on the world.


 

The significance for ROBOT ETHICS:To embed ethical self-regulation in artificial Autonomous, Intelligent Systems (A/ISs) will require an understanding of how people learn, interpret, reflect and act on the world and may require a similar decision-making architecture. This is partly for the A/IS’s own ‘operating system’ but also so that it can model how the people around them operate so that it can engage with them ethically and effectively.

 


This Blog Post: ‘It’s Like This’ sets the epistemological framework for what follows in later posts. It’s the underlying assumptions about how we know, justify and explain what we know – both as individuals and in society.
