Experiments in problem solving (Egidi (1996), Egidi and Narduzzo (1997) Egidi and Bonini (1999)) suggest that biases in problem solving may result from the process of mental editing by which subjects produce an imperfect and incomplete “representation” of the decision problem. From these experiments, in fact, stable sub-optimal routinized behaviors in game playing emerged and offered clear evidence that individuals, having discovered the solution of a problem in a limited domain, try to make use of the same solution beyond the original domain.This phenomenon has been previously discovered in a particular setting by Luchins, and defined “mechanization of tought” ; individuals remain locked into the procedure they have learnt, without reacting to new instances of the problem even when a new and better solution is evidently available.The experiments on “mechanization of thought” suggest that if individuals extrapolate the solution of a problem beyond the domain of optimality, this happens because they have categorized the situation incompletely or imperfectly. They make, in fact, systematic use of default classifications in order to reduce the short-term memory load and the complexity of symbolic manipulation. The result is the construction of an imperfect mental representation of the problem that nevertheless has the advantage of being simple, and yielding “satisfying” decisions. There are many different ways to categorize and represent a problem.One well-known method of problem solving is to decompose a problem recursively into sub-problems that are simpler to be solved, until elementary solvable sub-problems are identified. It is important to note that a given problem may be decomposed in a large variety of different ways that imply also different levels of abstraction in the categorization of sub-problems.  Every decomposition pattern is the result of a different way of codifying information at different levels of abstraction, and gives rise to a different strategy. For any given game or puzzle, we can compare the optimal decompositions of a problem with other decompositions, which are simpler and easier to be learnt, but sub-optimal. In Egidi (2001) “Biases in Organizational Behavior”, by analyzing in full details a specific puzzle, it is shown how biases emerge from the activity of problem decomposition and extrapolation. In the paper it is explained that individuals identify as building blocks of their representation sub-problems that do not coincide perfectly with an optimal decomposition. As consequence their categorization  embodies sub-optimal rules for solving the problem.Biases, therefore, are explained as “cognitive traps” in which individuals may stay locked in consequence of the fact that they save on the mental activity required to build-up a new representation. The next question is the stability of sub-optimal representations (on this point see Egidi (2002) “Rethinking bounded rationality”): when a player faces a new game configuration that does not match with the system of abstract classifications he has previously built-up, he must either add this configuration as exception to his system of rules or revise entirely his representation. Obviously, changing representation implies a heavy mental task: individuals may prefer to maintain the old system, perhaps adding few exceptions, rather than devising new abstract rules, because the mental effort required to redefine a sub-problems is greater than that required to memorize an exception. If the number of “exceptions” grows too large, and if they systematically occur during the game, the players cannot simply continue to memorize new exceptions; they must instead restructure the space of the rules, re-codifying information. In other words, they must change the representation; a change which may be highly discontinuous because it generally entails de-structuring the division of problems and re-designing the problem with new building blocks. This is of course an extremely onerous mental task, so that it is likely that the new example will be treated as an anomaly, without prompting re-categorization of the problem. This aspect of the problem shows striking similarities with the process of scientific discovery.  The paper Egidi (2002) Discrepancies: competing theories and ideologies as cognitive traps analyze some epistemological issues derived by the  approach described so far. Finally, the interrelation between representation and decomposability is outlined in Egidi M., Marengo L., (2002) “Cognition, institutions, near decomposability: rethinking Herbert Simon’s contribution”, while the more general consequences in terms of organizational change are briefly discussed in Egidi M., (2001) “Biases in Organizational Behavior”.
