Read in Swedish magazine about researchers trying to figure out how we show jelaousy and dissapointments. Think it actually was how we use our facial muscles.
The experiment set-up was as:
Person A and B know there are money that they can have. The total amount is known. Person A splits the money. Deciding how much money he (A) will have and how much B will receive.
Then Person B is presented to the split. Person B can accept or reject. If he rejects it none of the two gets any money. If he accepts they get what person A suggested.
A rational decision as B is of course to accept any split where he gets money. As long as he can get more than $0 he is doing ok. He will then have more than he had before the game started.
Apparently the researchers found persons that did not split the money 50/50. And also B-persons that would not accept any "unfair" split.
How would you do?
Would you as person A suggest a 50-50 split? Would you as person B accept any split where you get money?
How would greed, jelaousy, fair-play, tactics, feelings influence you? Would you play differently as B if the split and amount of money was unknown, i.e. you knew only you get money but you do not know how much money A gets?
Do the amount of money influence your thinking. Compare splitting $100 with splitting $1.000.000. Any difference?
