Markets act as cognitive prostheses enabling outcomes beyond individual rationality

Evidence

Indeed, markets themselves can be seen as prostheses in the sense that they enable human beings to achieve outcomes that go beyond their individual cognitive grasp. … The classic examples are the demonstrations that when placed in a double-auction market akin in its structure to open-outcry trading, both untutored human beings and even computerized “zero-intelligence traders” submitting “random bids and offers” achieve economic outcomes close to those predicted by theories that posit fully rational economic actors (Smith 1991; Gode and Sunder 1993, p. 119). — Donald MacKenzie, An Engine, Not a Camera, 1206
