Conformity
"... hearing an opinion repeated 3 times by the same person in a group had almost exactly the same impact as hearing the same opinion expressed by 3 different people in a group." [6:06]
"We can be self-defeating in our conformity. Say we have a group of people holding opinion X. Unbeknownst to the group, half of them secretly disagree, but due to the social penalties they have seen ditched out to a few individuals who have disagreed, they keep quiet. By conforming we add to the statistics of groups we don't actually belong to, and perpetuate the idea of majorities that may not actually exist. Imagine if none of us conformed in that way, how that would change the social landscape." [6:36]
Now let me see/hear how many of you "dare" to support the idea of a world without money!
