In his well known lecture “The surrogate world we manage”, St. BEER explained why and how our model of any factual situation or issue must be constantly (or at least frequently) revalidated (1973)
Modeling should be ideally a dynamic ongoing process , at least for five reasons:
1- our perceptions of anything in the world outside ourselves (and even inside!) are always parcialized, as our senses are such imperfect perceptive devices (even when aided by instruments)
2- our model construction is subjective by nature and depends on our acquired frames of references and their more or less frequently verified relative validity
3- we tend to confuse our model with the objective/reality (as we understand it)
4- after a time lapse - that can be long or short- the external situation has probably changed, and sometimes very much so
5- when we make decisions for action , apply them to the perceived issue or situation and the results are unsatisfactory, we tend to cling to our model, whatever the cost , and thus introduce our own evaluation problem as one more factor of disturbance
Consequently we should revise and recycle our models in a cybernetic way, considering registered external changes and the results of our own interventions as recurrent feedbacks
