Social Influence and the Wisdom of Crowd Effect

formfeed writes "A lot has been written lately on the crowd effect and the wisdom of crowds. But for those of us who are doubtful, the Proceedings of the National Academy of Science has published a study showing how masses can become dumber: social influence. While previous studies show how groups of people can come up with remarkably accurate results, it seems 'even mild social influence can undermine the wisdom of crowd effect in simple estimation tasks.' Social influence 'diminishes the diversity of the crowd without improvements of its collective error.' In short, crowd intelligence only works in cases where the opinion of others is hidden."

    As we all know, NPR listeners and NY Times readers all come to their conclusions based on reasoned consideration of all the facts. No herd mentality there. Not like those Limbaugh listeners and Bible-thumpers.

    By the Muslim definition of 'Muslim' Obama is an Apostate Muslim.

    According to Muslim tradition a person is a Muslim if their father is a Muslim or if they ever repeat the 'call to prayer' (which is apparently a 'profession of faith'.)

    Obama meets both these criteria.

    Of course in the rest of the world, where we get to pick our own religion, he is non practicing Christian.

    Some examples of things liberals continue to believe that are factually incorrect: Nazi's where capitalists, blankets can be 'infected with smallpox', FDR shortened the great depression, GWB was a deserter, Bill Clinton respects women.

    I take it you have yet to realize that reality has a liberal bias to it

    Said the liberal. That's the thing about your personal bias -- it is biased toward your personal beliefs.

    Non-liberals don't have the same liberal biased reality.

    The main problem with most liberals is that they firmly believe their bias is the only one that is, or even can be, correct.
