The one factor unaccounted for was their reputation after the game. It's likely worth more to them than taking the maximum payout and screwing everyone else. It would be interesting to see the experiment ran again with random people that nobody knows.,(reply>), @Tsarius I'd be interested to hear whether the play testers also played with real money though. I know that I personally will typically act 100% in my own interests when I play games with no stakes, but in a game with points that actually mean something id likely act differently,(reply>), Tbh i would have given 1000 each as agreed at the start of round 4 and kept 2000 and called it a day.,(reply>), @Tsarius I wonder if the playtesters played with real money. I honestly doubt it, or alt least not with 10k per game, as this would be just too expensive. But a lower price or even just play money would again totaly change the outcome of the game.,(reply>), I disagree, solely because the random person who wins the briefcase WILL NOT go back and try to share,(reply>), @Kristian There is a reason why twitch is considered as the worst cesspool among the bigger content production websites by many people. Not only does it generaly seem to have a higher amount of 'bad' people, it has a aignificantky higher amount of such people in the top vierwership ranks.
