Clive Thompson from Wired wrote a great piece on Groupthink; the main question is whether you can persuade people to like something by convincing them that others also like it?
And the experiments cited in the article gave interesting results that leaves us somehow worrying if our ‘destinies’ are determined by pure luck. It appears that for the very best and very worst, evolutionary forces would more or less elevate or eliminate them in long run but for most of the ones in the middle, their fate could be a matter of chance.
The article seem to imply there’s little way out of the problem of groupthink of such grand scale; it is suggested that the use of social cues for many decision-making is wired into our nature.
