Kludged

Is there reason to believe that our brains have evolved to make efficient decisions so that the details of the internal process are irrelevant? I develop a model which illustrates a limitation of adaptive processes: improvements tend to come in the form of kludges. A kludge is a marginal adaptation...

description Is there reason to believe that our brains have evolved to make efficient decisions so that the details of the internal process are irrelevant? I develop a model which illustrates a limitation of adaptive processes: improvements tend to come in the form of kludges. A kludge is a marginal adaptation that compensates for, but does not eliminate, fundamental design inefficiencies. When kludges accumulate, the result can be perpetually suboptimal behavior even in a model of evolution in which arbitrarily large innovations occur infinitely, often with probability 1.
