"One of the advantages of culture, then, is to attenuate the inherent limitation of fallible human cognition" (Caporael, 2001). This suggests that others can help a group member out that is in in some way lacking; in other words, reducing a shortcoming. Caporael left open, though, the other advantages, so I fill in...the other advantage of culture, then, is to augment the overall potential for accomplishment beyond that of the already-optimally-functioning individual; that is, a synergy or gestalt effect of a unified people.
