An individual can be thought of as the total set of concerns
for a specific organism. This is true whether the individual is human or not.
Like humans, a bird may be concerned for its offspring, like humans a dog may
enjoy spending time in the park. Human concerns reach higher levels of
specificity due to their cognitive flexibility – it is unlikely that either
dogs or birds pay much notice to Opera for example – and this feature permits
much greater individuation in the species. Whilst sharing many basic concerns,
humans very greatly in their learned concerns.
We can define a concern as anything which elicits an
affective response (a ‘reaction’) in an individual. A person with a passion for
architecture may react strongly to a building, whilst someone without that
interest may not even notice it. Our concerns govern not only the encoding of
experiences – it is the reactions themselves that are encoded, and form the
basis of cognition.
The question I wanted to consider here is the way in which
these concerns develop – in the process we call learning – specifically in
interactions with others.
A fundamental principle is that new concerns always spring
from the old: for example all creatures share a concern for painful
experiences. This enables a child that touches a fire to learn to fear fire, developing
a new concern in the process. A more subtle concern might be an innate concern
for status (and the desire to avoid embarrassment). Over an extended period of
time this is shaped into a concern for fashionable clothing.
Learning, in this sense, happens quite naturally and does
not require the intervention of other individuals.
Humans, in common with many species, are social. Social
species have certain mechanisms which ensure the harmonisation of concerns with
an ‘ingroup’ – and this extends so far as a culture. These mechanisms act to
suppress the expression of individual concerns in the interests of maintaining
group cohesion. For example, it may take you a long time to discover that a
work colleague is an avid Opera fan. This is because the work context implicitly
proscribes a set of behaviours that members of the group are expected to
conform to (norms) – and it will likely be outside of a work context that one really gets to know a colleague therefore.
Human interaction is also characterised by conversation, to a
degree that is peculiar among mammals. During conversation, two or more participants
explore the respective pattern of concerns that make them individuals.
This is a complex process, but the basic dynamics is simple:
each party takes turns sharing their concerns. In general this proceeds by
establishing shared concerns, then exploring finer levels of detail. The parties
then go back and forth, taking turns to share a little more of what makes them
an individual. Overall human relationships are governed by a relatively
simple rule: similarities good, differences bad. Two people who quickly
discover they have nothing in common will likely go separate ways.
The difficulty with this account so far is that is leaves no space
for learning: too much similarity and we become entirely homogeneous (cultures
vary in this regard). For this reason
(and to a degree that varies between individuals and cultures) we do indeed
seek out novelty – typically we like to establish a shared set of concerns as a
foundation for the relationship, which in turn provides a platform for
exploring new experiences which build on these. From the above explanation you
can see why this is so important – if you and I share a passion for fine food,
I might be persuaded by you to try a new restaurant, since I can safely assume
that my new concern can be built on the old, just as was the case with you.
Music recommendation engines ape this process – ‘if you like this, then you
might like this…’ – the process is simple: track the musical tastes of people
and then compare those with significant overlap.
This latter point is the heart of our question: when we are
merely ‘establishing rapport’ in a relationship, the focus is not on learning
but on discovering things that we both care about – a shared taste in music, in
holiday destinations, in food, in football, in movies – this is the foundation
on which we can build a relationship.
When it comes to learning, we are trying to shift the
concerns of an individual – this is the essence of learning whether we are
talking about fruit flies or humans. Even if we take a simple case of classical
conditioning, we are building one concern atop another – we shock the animal
each time we ring a bell, and it learns to fear the bell. It develops a new
concern (fear of a bell), based on the old (avoidance of pain).
In humans, the role of social interaction in learning is
considerably more complex – but the same basic mechanism applies. Here we enter
into a relationship not merely to establish rapport but to develop an
individual.
The first thing to notice is that development cannot take
place without sharing the concerns of the learner. Historically humans have
developed sophisticated methods for doing this: observation and conversation
for example. A skilled mentor will spend time talking to a person,
understanding who they are and what matters to them before offering guidance.
In recent years we have seen powerful technological
approaches, developed by companies wishing to sell their products but without
the additional complication of getting to know each person through
conversation. Instead, they are able to map what each of us cares about via our
online behaviour. In turn this enables them to sell in an ‘if you like this,
then you might like this’ fashion – in a way which follows a similar pattern to
learning.
Educational systems have yet to grasp the basic operation of
learning. In a future system, the starting point will be this ‘concern fingerprint’: a mapping of concerns, accomplished personally or digitally. It will be near
impossible to move an individual in the direction of some new concern if they
do not believe that the system/individual shares their concerns deeply.
This is also why children who are the product of extreme or
abusive early childhoods present a far greater challenge to a learning system –
since it is far harder for another person to share their concerns, and
therefore to build the kind of foundation on which to develop a learning path.
Someone, at the outset, has to say ‘I know how you feel’ and the child has to believe
them.
We can only speculate regarding the role that may be played
by machines in this process. A machine cannot share the concerns of a learner,
since a machine is not designed to react to any experiences in the way that an
organism does. It can, however, accurately map the concerns of similar users at
scale – in the way outlined in our music recommendation example. It can say ‘this
individual likes experiences A, B, C. Other individuals that liked A, B, C,
also liked X, Y, Z with a high degree of probability. I can recommend
experiences X, Y, Z to this individual therefore.’
This is significant because it suggests that a person may be
able to learn from an interaction with a machine – knowing full well that it is
a machine – purely because it is a proxy for human concerns. In other words, it
is fine for me to know that the machine does not care, if I know that it is
merely summarising the cares of other humans similar to me. Something similar happens when we read a book - strictly speaking, we are learning from the author, not the book.
There is an important difference between a marketing recommendation engine an a tutor however - a recommendation is relatively agnostic with respect to new concerns (at least within a given product domain). It may say 'if you liked this product, here's another of ours you may want to buy.' With education, we have some destination in mind. We probably don't want to create a population entirely comprised of ballerinas.
With education we want to 'steer' learning to some degree. We want to understand how to achieve one of a number of outcomes where an individual is happy and productive - rather than just guiding them down commonly-trodden paths.
This requires a much higher degree of sophistication: a 'learning path' proper has to be a series of stepping stones which take the individual from the things they care about today to the things they will care about tomorrow - without any of those steps being too great a leap. This is the great challenge ahead of us, with respect to education.
But today we are at ground zero. Our first step must be to
find out what people care about. Only then can we begin a learning journey.
