We all know that when we make decisions in groups, they don't always go right -- and sometimes they go very wrong. How can groups make good decisions? With his colleague Dan Ariely, neuroscientist Mariano Sigman has been inquiring into how we interact to reach decisions by performing experiments with live crowds around the world. In this fun, fact-filled explainer, he shares some intriguing results -- as well as some implications for how it might impact our political system. In a time when people seem to be more polarized than ever, Sigman says, better understanding how groups interact and reach conclusions might spark interesting new ways to construct a healthier democracy.

    This is the best use of graphics in a TED talk yet
  • @ColorfulHalo
    This is quite fascinating! Since I work in a team-driven environment, trying to reach group decisions is something I deal (and sometimes struggle :'D ) with daily.

    a) A group of Ted talk guests are probably of above average intelligence, self reflective, critical thinking and eloquent, even though they are from different continents, they are most likely from the respective intellectual elite. 2) These experiments tested sponaneous, non-essential compromises. What happens when you add skilled politicians and stakes to your argument?

    This was incredibly interesting and diserves more views.
  • @RamzaBeoulves
    The same result was observed in 12th grade and I always found it to be a powerful experiment.
  • @aliail2998
    are these results going to be published somewhere?
  • @funny-video-YouTube-channel
    Such experiments are very important, before we build our Internet Democracy, on the example of the Swiss council system.
