We need to read, again, Armen Alchian (1950)  to understand this. In a world of uncertainty, no one knows the correct answer to the problems we confront and no one therefore can, in effect, maximize profits.

Adaptive efficiency, therefore, provides the incentives to encourage the development of decentralized decision-making processes that will allow societies to maximize the efforts required to explore alternative ways of solving problems.
