Error in description of experiment
Daniel does it amazingly well, but describes the essential experiment wrongly on 09:20-35. While he says participants get high reward for high performance, medium for medium etc., the experiment must be organized differently in order to show the results he describes afterwards. Namely the participants must be in 3 groups: one getting a high reward, second a medium reward etc. He makes the same error in https://www.youtube.com/watch?v=u6XAPnuFjJc which surprises me. Do you agree?
