Possible Impat of this Approach


Possible Impact of Indirect Perception Philosophy on other Disciplines


When we shift from a DP philosophy to IP philosophy, the questions we tend to ask become more directed at constructing models.  For example, instead of posing questions like, “are humans basically good, or bad?” we are inclined to ask, “How best can we model human behaviour?”  The “are we good or bad?” question suggest that we should choose one of these very simple options, while the alternative approach suggests that we can create  a model to represent human behaviour.  Perhaps a more sophisticated models like, “humans tend to be “good” when not stressed and tend to become “bad” when stressed”.  This model sends us looking for examples where economic and social stresses affect behaviour and to also examine antisocial (bad) behaviour and ask, where are the stresses?  If we find that this model works well most of the time we can use it to help understand human behaviour without making any commitments about human beings being good or bad. 

When using simple models to represent complicated systems it is likely that the model will not adequately account for all behaviours.  If the intention is to have a model that exactly represents we will need to reject the simple model and construct another, possibly a more sophisticated model.  But in many cases (especially when dealing with social sciences) we are willing to sacrifice accuracy for simplicity and simple models are used even when we know that they are not always accurate. Using the IP methodology we can determine the level of accuracy and precision we need. We do not expect that the model will be perfect as we understand that it is a very simple model representing a much more complicated world. We can also limit the range of conditions under which we apply a model  and possibly use different models for different circumstances.  We can, for example, use the circumstances to determine which of several possible models we use to model human behaviour.

Another example: prejudices have bad press; we believe them to be bad and try to get rid of them.  Doing this suggests that we have asked, “are prejudices good or bad?” and, having concluded that they are bad, we have taken appropriate action.  An alternative approach, encouraged by an IP approach, would be to create a simple model that seeks to explain this behaviour, test it and use it if it works.  I think that models that have a good chance of success can be developed around the following approach.

We cannot eliminate prejudices, as human decision-making is inherently prejudicial.  The everyday situations we face have a complexity that defies rational decision-making and we have to rely on our prejudices to, for example, select clothes, religious beliefs, political parties, where we live, what we eat, how to make a living, our friends, beliefs, etc.  All our likes and dislikes are based on prejudices. The majority of these prejudices are very helpful and so it is highly unlikely that we would wish to eliminate this mode of decision-making, even if it were possible.  Let us therefore accept that we are prejudicial and ask why we are sometimes prejudicial in antisocial ways.  It is the antisocial prejudices that we want to eliminate and so instead of trying to get rid of prejudicial decision-making we need a model that helps us understand why we make antisocial decisions.  There is an immediate tie in to the model discussed above and we can associate antisocial prejudices with stresses; threats that we may be conscious of, but which can affect us even without our being conscious of them. 

This alternative encourages an approach that includes introspection, understanding and exploring our own prejudices, while the previous approach encourages us to judge, blame and punish those who exhibit certain antisocial prejudices.  Changes like this can have a profound impact on our society over time as it seems to suggest that we try to mitigating  the circumstances that result in antisocial behaviour, rather than take the alternative route suggested by a DP approach.

A wider appreciation of the IP approach will also have an impact on science.  It is still popular to teach that science discovers natural laws (rather than “science produces models to represent the environment”).  This idea that science discovers laws has several consequences that can possibly inhibit a student’s understanding of science.  Let me illustrate with an example.  Our standard model of the environment includes a past and a future and something we call "time" that puts these in a sequence, but the external world this represents only exists in the present; past and future only “exist” in our mental model and are not a part of the external environment this model represents. 

If we keep this in mind when we try to understand something like Einstein’s relativity theory, we don’t have to try to figure out how time and space interact in the external environment, as these only interact in the model being used to represent the environment.  Taking this approach allows us to fundamentally separate theory from what the theory represents and I think that this will make it easier to understand scientific theory and its limitations.  Einstein’s theory evolved from trying to take into consideration the limits of our ability to measure things like time and space.  He speculated on what the observer experiences and included this in his theoretical considerations.  Before Einstein a direct perception perspective was assumed and the observer's limitations did not play a role.  It was assumed that we were in direct contact with the environment and this encouraged the popular interpretation of science as being able to discover ultimate truths, nature’s laws; the laws were assumed to be in nature, not in our imagination – a fallacy that is exposed by the model building approach (note that Newton rejected this fallacy and argued that his models were simply models).

Separating the model from what is being modelled can also help with understanding the application of statistics.  We can think of statistics as a method that can be used to create an abstracted (simplified) representation of a complicated environment.  The statistical tools available also show under what conditions this model can be adequately representative.  For example, in applying statistics to come up with Boyle’s law we assume random molecular motion.  This motion is random in the model.  What happens in the environment may not be random and may instead follow various causal processes, but at the level of abstraction of the model we are declaring that, for our purposes we can consider the molecular motion to be random. By conceptually separating the model from what the model represents we can ignore detail that is unimportant and simplify what has to be conceptualised, making it easier to understand.

I need to emphasise the underlying limitation of this model building methodology.  When the model makes accurate predictions we cannot conclude that this model shows how some particular feature of the environment “is”.  We can only claim that the model adequately represents some aspect of the environment, under these particular circumstances
