Rationality and Contraction
Rational procedures set themselves (attractive) goals. This immediately leads to a contraction of perception, response-readiness and goal achievement activities. The problematic aspect here (and in this instance it is solely about this), is the fact that the environment is becoming ever more ambiguous and equivocal. If there are now goals with which a system is strongly identified, all those phenomena in the environment are filtered out as information which is related to the goal and which may help or hinder it.
Therefore, important things, which have nothing to do with the goal, might be overlooked. You have adhered to the training plan for the marathon run, and have not noticed that the wife has moved out. It can be deduced from this that goals usually trigger the abilities which a system already possesses (sportiness). Not least therefore, it is very rational that goals are selected as a general rule.
This, however, is based on the error that you also desire that, which you are good at. In addition, it leads to an impoverishment and, therefore, to a loss of robustness and ability to improvise within the system. Ultimately abilities, which would also be very important, (in our example, ability to emphasise, and closeness competence) are not developed.
