Can someone point me to a source for this study:
There was a group, in which a dominant person established a belief in a false statement by speaking with high confidence. The group still believed in the false statement even after that person had left the group. Newcomers to the group accepted the false statement through normative social influence.
I have read about that either by Kaneman, Ariely, Chabris/Simons or maybe Thaler but can't find the passage anymore. And is this still valid?
I'm not talking about the story with the apes, the banana and the ladder by the way - I know that never happened.
