The reservations department of a major airline meets weekly to discuss ways to improve the sales quota. whenever they meet, sam (a new employee), is the only one to express a differing opinion. at first the leader just asked him not to rock the boat, but as time went on, the group began to ignore sam and speak as though he had not said anything. this is a sign of what symptom of groupthink?
rationalization.
illusion of unanimity.
direct pressure.
self-censorship.

The correct answer would be option B) Illusion of Unanimity.

this raises an interesting question: just what’s so bad about incest? sure, having sex with your dad or your sister seems gross — but why? some anthropologists have argued that incest taboos are learned social conventions. this explanation, however, doesn’t make sense to me as it does not explain the widespread existence of anti-incest mechanisms in creatures ranging from cockroaches to chimpanzees. second, the incest taboo is about as close to a universal law as human moral rules get.

why should mechanisms to avoid incest be so widespread both in nature and across human societies? the answer is simple. the problem with having sex close with relatives is that there is an astonishingly high chance that your offspring will be born with a serious birth defect.
