I'm on mobile (and sleepy) rn, so I don't think I can properly respond to all your points, but thanks for this comment, I found it overall very constructive!

I'd just like to question one point for now

If 10 people in a group agree to leave 10,000 USD on a table, such that after 20 minutes, they can all split it amongst themselves, and then turn off the lights in the room and plug their ears in the meantime, someone if not multiple people are going to try and take it all for themselves.

Where are these people from? Urban, Rural, which country, which region etc, culture can have a big influence on that, I'd guess more collectivist cultures would have a different approach to this experiment than individualist ones such as you described. The country I live is also individualist so I see your point, but is all of humanity really like that?

A Native American tribe of 10 people would probably coordinate to be able to split the money, or even to invest collectivelly in their own village for example. A group of 10 New York executives with survival of the fittest mentality would probably act like you described.

Just some food for thought, hope you or anyone reading finds this interesting.
