J.C. was the source of the key biological idea, e.g. in Chappell and Sloman (2007), extending ideas in an earlier joint paper at IJCAI 2005. A comment by Peter Tino (October 2019) about the complex biochemistry of gene transcription probably underlying the meta-configured genome mechanisms, prompted a separate (tentative) document about requirements for molecular mechanisms (Sloman, 2019-dna).
During September 2020, some important additional ideas summarised below emerged from a conversation betwee A.S. and theoretical physicist Anthony Leggett https://physics.illinois.edu/people/directory/profile/aleggett
Background information and discussion of implications, with further links relating to these ideas, is provided below -- after the introductory video.

This is a highly compressed (work-in-progress) introduction to the meta-configured genome theory developed in collaboration with Jackie Chappell in Biosciences at Birmingham.
It replaces the familiar distinction between altricial and precocial species with a space of types of complexity in genome-expression.
I'll describe simple forms of gene expression, and then add several layers of complexity, including types of gene expression that produce parametrised, i.e. incompletely specified, structures that obtain their parameters from results of earlier gene expression. This allows environments, including social environments, to add multiple layers of sophistication to competences produced at different stages in the evolutionary history of a species, during later stages of development of individuals, but not on the basis of conventional learning. (This is crucial when learning from mistakes is impossible, because mistakes are likely to produce death or serious injury!)
This renders old debates about types of "modularity" (especially innate modules) in human brains or minds, out of date, since they ignore important types of multi-layer parametrised modules, and the roles of parametrised genetic specifications, without which human languages, and many human competences, including ancient mathematical competences, would have been impossible.
I'll present an illustrative collection of layers of increasing sophistication added during development, where each new layer is only partly specified genetically, and uses information acquired previously, to provide "parameters" to fill gaps in the new specification. This phenomenon seems to be most visible in language development, but I suggest its use goes far beyond language development.
The ideas are still at an early stage of development and little is known about implementation details, which, in humans, are likely to depend on sub-neural forms of chemical computation, that are not concerned with correlations and probabilities, but with structures and structural relationships and changes in compositional processes. Some of these ideas are familiar to theoretical linguists.
Our claim is that the key ideas are not restricted to evolution and development of linguistic competences, but are more generally applicable -- e.g. to spatial reasoning abilities underlying ancient mathematical competences.
After the above introduction, the video attempts to explain how different parts of the genome are activated/expressed at different times, making use of previously stored information gained during earlier phases of gene expression -- as summarised (less clearly) in this diagram:

Apologies for video and audio quality (and my tendency to make explanations too long):

Is there an argument that physical systems with layers of constraints (e.g. by adding new design features on top of old designs) acquire forms of behaviour, and behavioural capabilities that cannot be expressed in terms of the language of fundamental physics, and instead need layered languages? This proposal turned out to be unconvincing with a strong "cannot". So I later revised the proposal to suggest that the higher level behavioural capabilities cannot be usefully expressed in terms of fundamental physical particles for use by by real time control systems (e.g. parts of organisms controlling assembly of new parts). In that case evolution may have developed multiple control-languages for use by controllers operating on structures, e.g. to extend the structures, or to use them to operate on other things, e.g. controlling motor system behaviours by controlling muscles and lower level controllers.
These control mechanisms with special purpose control languages may be scattered all over the body. However if they are to be coordinated to produce some desired complex behaviour, e.g. walking to an object, picking something up, trying to escape from something, then there will need to be centralised forms of control, presumably in brains, communicating with all the sub-controllers in different parts of the body. This may in principle be achieved through multiple neural connections. But if that sort of control is either too slow or too difficult to orchestrate centrally, then perhaps advantages can be gained by non-local control based on quantum-physical mechanisms. Until someone can specify such mechanisms in detail this is just hand-waving. But it may be a useful start.
Some of the background to this suggestion is provided by Sloman(2020).
One of the sub-goals of the M-M project is to explain how spatial reasoning mechanisms in minds of ancient mathematicians (and other spatially intelligent animals, including squirrels, some nest building birds and pre-verbal human toddlers!) work. Some suggestions about mechanisms, based ultimately on chemical processes underlying biological evolution and mechanisms of genome expression, as summarised in the Meta-Configured Genome theory presented above, are referenced below.)
Ancient mathematicians, such as Archimedes, Euclid, Pythagoras, Zeno, and many more, made profound discoveries, e.g. in geometry and topology, that are still in constant use world-wide by scientists, engineers, architects, and mathematicians. (Though unfortunately no longer taught to all bright students at school or university, in many countries, since about the middle of the 20th century, when seriously flawed educational decisions were taken in several countries.) Immanuel Kant identified the problem around 1781 but his ideas summarised in Sloman(2018) (and defended in my 1962 DPhil thesis), have been ignored or mistakenly rejected for over half a century.
Researchers who claim to have implemented geometrical or topological reasoners that model such discovery mechanisms using either logic-based theorem provers combined with suitable axioms and definitions, or trainable neural nets trained on many test cases fail to understand two points made by Immanuel Kant (1781), namely that the ancient discoveries were neither analytic, i.e. derived using only definitions and purely logical reasoning, nor empirical, e.g. based on statistical evidence acquired (e.g. by a neural network) from collections of tests or experiments. (Kant's distinctions were summarised in Sloman(1965).) The ancient discoveries were about possibilities (e.g. possible geometrical constructions or arithmetical operations), impossibility (e.g. no number can be the largest prime; no power of 27 can be divisible by 28) and necessity (i.e. being incapable of being false, e.g. every even power of 6 must be divisible by both 4 and 9, and no planar convex polygon can have an even number of sides and an odd number of angles. [How do you know?]).
No statistics-based neural network can represent impossibility or necessity, let alone establish it as mathematicians regularly do with proofs of various sorts. (The ability to establish necessity does not have to be infallible: mathematicians can and do make mistakes, then later notice the errors and in many cases correct them, sometimes with great difficulty, as documented by Lakatos (1976).)
The required mechanisms have not yet been replicated in AI or explained in psychology or neuroscience, and the requirements are currently ignored or misunderstood by most philosophers of mathematics, psychologists, neuroscientists and AI researchers. (They have not read and understood Kant, and checked out his claims in personal experience of making even simple mathematical discoveries -- a serious flaw in current educational practices!)
Our work identifies a (gradually emerging!) new direction in which to seek such explanations -- namely trying to understanding evolutionary origins and the mechanisms they produce rather than doing laboratory tests on humans and other animals. This is one of the key strands of the (Turing-inspired) Meta-Morphogenesis project mentioned above, begun in 2012 -- the Turing centenary year.
Ultimately, this search will take us into aspects of fundamental physics involved in the mechanisms of genome replication and gene expression, extending Schrödinger's profound insights in (1944), helping to inspire the discovery of the structure of DNA a few years later. But our theory has not yet reached that stage of development. So we focus only on well-known facts about human and non-human forms of intelligence and the kinds of consciousness they support, and ask how such mechanisms could have been produced, and extended, over time, in a physical universe, in which the vast majority of biological processes depend on chemical mechanisms.
This presentation of the theory introduces new (Oct-Nov 2019) speculations about the (bio) chemical details underlying Meta-Configured Genomes. The theory is still too vague/abstract, though some more detailed but still incomplete thoughts and questions about the biological mechanisms are presented in (Sloman, 2019-dna).
If the speculations are correct, a fully developed version of the theory, showing how biochemical mechanisms, all implemented ultimately in physical mechanisms, on which they build new powers, can themselves subsequently be the basis of (physically, chemically, and metaphysically) novel biological phenomena, including various increasingly complex novel forms of biological information processing (e.g. used for intelligent control of actions, and eventually, in humans, used for language development) that rely on increasingly complex biological mechanisms, without which they could not exist, and which, in turn, depend on properties of physical matter, which are not available in Newtonian mechanics. I.e. if Newton's theory described all forms of causation, life could not exist. (Not even rocks could exist since Newtonian particles could not form a large rigid structure -- his physics did not include chemical bonds!)
This is implicitly a metaphysical theory (as well as a scientific and epistemological theory) -- metaphysical insofar as it explains how a purely physical world can become the basis for a world including various kinds of information-users of steadily increasing metaphysical abstractness and complexity. In the terminology of Wilson(2017) we are talking about complex forms of metaphysical causation as grounding psychological phenomena in biological phenomena which are grounded in physical phenomena. I used to think that the required competences could be implemented in digital computers using new AI techniques, but it now seems that ancient mathematical forms of consciousness depend on brains using chemical information processing which is not restricted to digital information processing: some of the molecular changes during gene expression, for instance, are inherently spatial and continuous although they also involve discrete changes produced by catalytic mechanisms then create or remove chemical bonds, processes of the sorts shown to be required in reproductive mechanisms, in Schrödinger (1944).
There are many complex details not mentioned here, including evolution's essential use of not just the original physical construction kit but increasingly complex novel construction kits produced by evolution and used for producing (and maintaining or repairing) increasingly complex (and in some cases increasingly abstract) mechanisms Sloman (2014-18).
Many ancient spatial competences, in humans and other intelligent species, required abilities to detect changes in spatial relationships including changes in relative size, distance, orientation, and topological changes, e.g. containment within or connections between perceived regions of the environment. Not all animals with eyes and brains have the same kinds of spatial awareness, and there may not be a common ancestor e.g. for eyes of insects, molluscs, and vertebrates and they represent spatial structures and processes in different brain mechanisms, with different evolutionary histories.
In humans, and apparently other intelligent animals, spatial perception provides information not only about what light patterns hit their retinas and the locations, shapes and surface properties of objects from which received light has been reflected, but also information relevant to processes that can or cannot occur in the environment and also information about actions the perceiver can or cannot perform: this goes far beyond Gibson's affordances (Gibson 1979, Sloman 2009).
More recently evolved mechanisms provided individuals with abilities to become conscious of spatial possibilities, impossibilities and necessities derived from spatial structures and relations. Such abilities are of use in practical decision making and control of actions.
To explain those abilities we need a theory of the nature of various forms of spatial consciousness (e.g. in humans at various stages of development, and in other organisms with varying kinds of spatial intelligence, used in controlling actions and in selecting and achieving practical goals, e.g.: making a stable nest using semi-rigid twigs (corvids), or hanging nests woven from a large number of long thin leaves (weaver birds), or squirrels getting nuts from "squirrel proof" bird-feeders, or tree climbers rejecting impossible routes through tree branches, where errors can be fatal, e.g. for orangutans as described below. These requirements rule out use of purely statistics-based trial and error learning! Strong but not conclusive evidence is not of much use to dead infants.
Two crucial features of such intelligence are not wasting time by failing to understand relative distances or sizes, or relative difficulty of motion or grasping; and not risking life, by failing to recognize serious dangers, e.g. avoiding actions likely to be fatal or lead to serious injury. A particularly important feature of natural intelligence is ability to detect and "prune" impossibilities, to avoid attempts that will necessarily lead to failure, injury or death.
This involves being able to detect necessary consequences of available changes, e.g. in order to reject possible actions that will necessarily fail disastrously to achieve desired objectives, or to select actions that will necessarily succeed -- e.g. will successfully make a gap too small for a certain object to move, or escape, through, or make one large enough to serve an important purpose. Betty, the crow mentioned below, clearly seemed to understand the difference between moving a straight piece of wire and moving a curved piece of wire in the vicinity of the otherwise unreachable handle of a bucket of food. Moreover, although this was not mentioned in the original published reports, the online videos show that she clearly understood several different ways of using features of the environment to transform a straight piece of wire into a bent or curved piece of wire. Achieving her goal of obtaining food did not remove a tendency to think of, test, and use alternative means of achieving the same goal in the same sort of situation.
Are there impossibility detectors (or necessity detectors) in brains?
Obviously action selection involves detection of possibilities. Intelligent action also requires ability to decide that something is impossible, or will necessarily succeed. What sorts of brain mechanisms can make such forms of consciousness possible? The mechanisms may be too complex to be studied directly but we may get clues by investigating precursor mechanisms, starting from information processing mechanisms in the very earliest life-forms and trying to identify ancient evolutionary transitions producing increasingly complex forms of information processing many of which may still be in use, though not directly observable.
Because brains of recently evolved intelligent species are far too complex to be studied exhaustively directly, years of diligent research may miss crucial features. But we may be able find clues about mechanisms relevant to abilities to detect possibility, necessity and impossibility without risky trial actions, if we can identify, at least in outline, the evolutionary trajectories by which those complex forms were built up, i.e. trying to find out how biological evolution, starting with one or more minimal forms of life, or prebiotic physical/chemical structures, was able eventually to produce the minds of animals with spatial reasoning abilities, including, eventually great ancient mathematicians who used spatial intelligence to make deep non-empirical discoveries that are still used by mathematicians, scientists, engineers, architects and others. A high level survey of possible evolutionary and developmental trajectories may provide clues that would otherwise go unnoticed. One of those clues is the important role played by meta-configured genomes, with functions summarised in the above video, and expanded below.
Conjecture: evolution of meta-configured genomes, of the sort described in the above video, was a crucial factor in the processes that produced modern mathematical consciousness. This could explain how important abilities that are not available at birth, develop several years later, without being derived by general-purpose, e.g. statistics-based learning mechanisms from evidence acquired in the intervening years. (How could the concept of impossibility and abilities to detect impossibility be acquired empirically?)
As Immanuel Kant(1781) noticed, the fact that the discoveries are non-empirical, or a priori does not imply that the knowledge is available from birth, or earlier. (Some of Kant's ideas are presented and defended in Sloman(2018)). The meta-configured genome theory explains why his theory might have been right, despite being incomplete (as Kant admitted), because according to the theory (a) not all the evolved capabilities in a species are available for use at birth, and (b) some of the evolved capabilities are schematic and need to be developed late, so that their general specification can be combined with information acquired by the young learner from the environment earlier.
E.g. consider how playthings of human children must have varied over thousands of years, and yet provided information about lines of sight, types of change in spatial relationships with necessary consequences (e.g. seeing more or less of a distant scene as you move left or right while looking past a vertical edge) and many types of impossibility -- some illustrated in http://www.cs.bham.ac.uk/research/projects/cogaff/misc/impossible.html (also pdf).
A crucial feature of these conjectures is that motivation is not necessarily reward based, and need not involve use of probabilities, as presupposed by theories of decision making based on "expected utility" since the mid 20th Century [Luce & Raiffa 1957] that have seriously misled many researchers in psychology, neuroscience, social science, economics, and robotics/AI.
An account of an alternative mode of learning and discovery should also undermine shallow, popular, recent characterisations of consciousness proposed by Nagel(1974) and others. There were deeper insights regarding consciousness in James(1879), but, like Kant, he lacked important ideas about required forms of computation.
There are many different kinds of consciousness (e.g. enjoying a smell, or a game, being puzzled by an unexpected event, recognizing the validity of a proof, finding a previously unnoticed flaw in a proof, composing a piece of music, wondering how life began, and many more), so any deep theory of consciousness must accommodate a rich variety of structured contents of consciousness, including different kinds of mathematical consciousness, such as discovery of previously unnoticed mathematical facts, wondering why they are true (i.e. being puzzled by them) and eventually understanding why they are true.
As Immanuel Kant noticed, this involves understanding relationships between different aspects of contents of consciousness, including explanatory mathematical relationships.
For some animals, understanding impossibilities and necessities is a matter of life and death: for a young orangutan learning to climb through tree foliage like its mother, mistakes would be fatal or cause serious injury. Instead it needs some understanding before trying that some actions will fail and others will succeed assuming there is no deception at work. How is that initial understanding represented (a) in the genome, (b) in the brain, and what what brain mechanisms allow the information to how be extended and modified over time. "Visual cliff" experiments on human infants and other animals are relevant to this: https://en.wikipedia.org/wiki/Visual_cliff, although there are debates about interpretations. Our main questions are: How is the "inherited" information about such things represented chemically in the genome, and how does that information become available during later development? What changes in brains when the information is later modified and extended?
There are many other animals with great spatial intelligence including honey badgers https://www.youtube.com/watch?v=c36UNSoJenI squirrels, elephants, orangutans, and the amazing portia spider:
A portia spider can sit stationary for several minutes looking around to work out a route to a point above its prey (e.g. another spider, at the centre of its web). It then follows the route even when it can no longer see the prey, making detours if necessary and avoiding branches that would not lead to the prey: "By visual inspection, they can select, before setting out, which detour routes do and do not lead to prey, and successfully perform a detour with no further visual contact with the prey". M. Tarsitano, 2006
Route selection by a jumping spider (Portia labiata) during the locomotory phase of a detour, Animal Behaviour, 72, Issue 6, pp. 1437--1442, http://dx.doi.org/10.1016/j.anbehav.2006.05.007
That raises questions in philosophy and psychology of mathematics, about what spatial understanding is, and what sorts of mechanisms can find and use a proof about a sequence of actions that will achieve a desired result. How does such understanding differ from and share with to other kinds of consciousness -- questions that are not addressed here. The main point is that explaining the possibility of consciousness of geometrical and topological truths and the validity of mathematical arguments about them is closely related to everyday consciousness of spatial structures and processes, at various stages of development, in humans and other animals. (I believe Kant understood that.)

(End of background ideas)
I have assembled a draft tutorial introduction to processes making use of genetic structure in a cell, encoded in DNA, for reproduction and other purposes -- e.g. structure formation, growth, combination of structures, replication of structures, assembly of structures into whole organisms.
(Sloman, 2019-dna): provides an incomplete and provisional summary of different apparently relevant uses of DNA in reproduction and development (especially gene expression), with links to some online video tutorials. This may be a useful early step for some people wishing to think about mechanisms capable of explaining the evolutionary and developmental phenomena, including evolution and development of forms of mathematical consciousness ignored in most theories of consciousness.
The problem of explaining mathematical consciousness is more closely related to genome expression during development of an individual organism, than to the role of the genome in reproduction. In particular, we need new insights into how the genome influences production, development and functions of information processing mechanisms,
Genome expression is far more complex, context-sensitive, and variable than genome replication (structure copying), and provides rich and varied opportunities for the environment to play a role -- sometimes a delayed role, if information acquired when triggered by a genome is not used till a later stage of gene-expression occurs, as explained in above.
In his little book What is Life?, (1944), Schrödinger explained the crucial role of quantum mechanisms in making reliable reproduction possible (later shown by Crick, Watson, and Franklin to be based on the double helix structure). As far as I know Schrödinger did not mention the equally important role of quantum mechanisms in the production and use of chemical structures in gene expression within developing individuals, a process that is far more complex and variable, and more extended in time, than production of a new viable fertilised egg. I have tried to give more (still sketchy and provisional) information in (Sloman, 2019-dna).
One way to summarise my main thesis:
A huge amount of recent and current research attempts unsuccessfully to show that neural networks in brains account for important results of gene expression that require quite different mechanisms, e.g. mechanisms supporting compositionality and discovery of impossibilities and necessities -- which is impossible for neural networks that merely compute probabilities from statistical evidence (observed relative frequencies).
This work is partly inspired by Immanuel Kant's philosophy of mathematics (1781), defended in my 1962 Oxford DPhil thesis.
A very brief summary of the distinctions on which Kant based his claims about
mathematics (in opposition to David Hume) is here:
A. Sloman, 'Necessary', 'a priori' and 'analytic', Analysis, 26,1, Oct 1965, Pages 12-16,
A closely related online paper (written 2018-19) is referenced below.
Some examples (videos and photos not included in my presentation above):
Here are some online examples illustrating research done on spatial intelligence of New Caledonian Crows when Jackie Chappell was at the Oxford Behavioural Ecology Lab:
The Trial 7 video was referenced in world-wide news headlines in 2002.
Notice the variety of different techniques Betty used to make hooks for the task:
having found a method that worked, she continued exploring alternative methods.
More pictures showing Betty and Abel (another crow) solving problems.
It is sometimes suggested that if such animals solve related problems in their natural habitat then that reduces the interest or importance of their abilities. However, that additional information does not explain what brain mechanisms are involved, what information they use, and how they use it.
A related, more familiar, biological concept: Morphogenesis
There are genetically programmed changes during development that are more spectacular than the (often subtle, and hard to detect) changes in cognitive competences discussed here. In particular, genetically programmed changes of physical structure, including quantitative changes in size, weight, strength, and chemical properties of various body parts are well known, including dramatic examples of morphogenesis in insects and frogs from a larval stage (e.g. grubs or caterpillars to butterflies and moths, as illustrated in these -- and many other -- online videos
and changes from tadpoles to frogs
Clearly all those changes of physical structure and possibilities for physical action must also be accompanied by changes of the information processing mechanisms and the processes concerned with control of the movements/behaviours of those new physical parts, including switching from swimming in water or crawling on physical surfaces to flying using newly formed wings in butterflies and moths.
There are also cases of dramatic changes of behaviour at a certain stage of
development that are not based on changes in physical form, e.g. changes from
individual foraging to swarming behaviours in locusts, presented by David Malone
in the "Jekyll and Hyde" video here:
(I wish he did not follow the dreadful fashion among TV producers of adding totally unnecessary background noises making it hard for many people of my age (and younger as well as older) to make out what is being said http://www.cs.bham.ac.uk/research/projects/cogaff/misc/bbc-learning.html.)
The Meta-configured Genome hypothesis generalises those ideas to include changes in forms of information processing that occur in stages, and where later stages make use of information acquired during earlier stages, generalising the familiar notion that in morphogenesis later stages of physical development make use of physical materials acquired during earlier stages (including much feeding and digesting behaviour). Physical morphogenesis can be very spectacular, whereas information-processing morphogenesis involves intricate internal changes in information-processing mechanisms implemented in physical mechanisms, that are sub-microscopic and totally unobvious to those who study perceptible developmental changes.
These comments are also relevant to plants, insofar as they change not only their physical forms during a lifetime, but also the forms of control of physical materials during growth and seasonal changes, as well as reproductive behaviours.
The Oxford talk related the Meta-Configured Genome thesis to problems of explaining how brains make possible the ancient, deep, kinds of mathematical discoveries leading up to (and beyond) Euclid's Elements and how they (brains of humans and other intelligent animals) solve related practical problems based on recognition of spatial possibilities, impossibilities and necessities.
It summarises David Hume's and Immanuel Kant's differing views on the nature of knowledge, including mathematical knowledge, and suggests that Kant is closer to the truth about the special features of mathematical discoveries, including the ancient discoveries leading up to and beyond Euclid's Elements.
The notes include a section on "Branching evolved forms of consciousness" (including varieties of spatial consciousness) available here, challenging assumptions shared by most (?) who write about the nature of consciousness.
It does not seem to be widely understood that there are more varieties of consciousness than can be captured within the currently fashionable (but seriously misleading) slogan that there is a "hard" problem of conscious related to "what it is like (or feels like)" to be in some state. I think William James over 140 years ago, had a fairly deep understanding -- expressed in his (1879) -- of the reasons why there must be varied forms of consciousness produced by biological evolution, not captured by most recent discussions of the nature of consciousness (e.g. I felt that that biological variety was ignored by most speakers at the Oxford conference on consciousness, which provoked this document.
The discussion of evolutionary and developmental branches in types of consciousness implies that most theories of consciousness are inadequate insofar as they fail to account for the variety of types of naturally occurring forms of consciousness, including mathematical consciousness and closely related forms of spatial consciousness, at various stages of development in humans and other animals, and in their evolutionary ancestors.
Also missing, as far as I know, is an account of the historical stages through which evolution arrived at some genomes that only partly specify designs, leaving gaps to be filled by previously acquired information from other sources (parameters) as new mechanisms develop.
Perhaps one of the early requirements for such mechanisms arose in species that grow in size and strength so that mechanisms are needed for controlling both the growth and the use of those mechanisms in ways that take account of changes in the size, weight, and strength of movable parts, and consequential changes in their biological uses: i.e. the control mechanisms need to take account of changes in both "inputs" to control mechanisms and "outputs" (to motor subsystems).
Consider, for example, recent changes in childhood environments of humans, including the introduction of many computer-based and/or internet-based electronic devices: if the human genome has the right level of abstraction at different stages of development, children don't need to be born with a new type of genome to cope with the new environments. An earlier example was migration between different sorts of terrain, e.g. from warm parts of the planet to much colder regions, or from plains to steep mountainsides, or more generally changes in food sources and actions required to acquire and consume them.
Species vary in their ability to adjust developmental processes to changing environments. In extreme cases the adjustments require evolutionary time-scales because the genome has to change, instead of gene expression being changed by differences in "input parameters".
I am not using "information" in Shannon's sense (i.e. referring to syntactic or
structural properties of information bearers) but in the much older, more
abstract, sense of "semantic/referential content" familiar, for example, to the
novelist Jane Austen, over a century before Shannon, as explained in:
http://www.cs.bham.ac.uk/research/projects/cogaff/misc/austen-info.html (also PDF) --- and, of course familiar to many people centuries before Jane Austen.
I call this "Architecture-based motivation", often observed in young humans and some other species whose reflex switches of attention and motivation depend on evolved mechanisms that have proved useful in ways none of the individuals can know about at the time, as explained in Sloman(2009--2015).
