80/20 1 No Sorry, I'm a person too. When the cards are all in my hand, you should try to appease me instead of offend me. There was a 50/50 split. It couldn't have been easier. So, since you decided you are obviously better than I am. You get nothing. Enjoy it, I know I will. Negative
2 No If you would have been less greedy than maybe we would have gotten some money. Treat everyone as you want them to treat you. Negative
3 No Should not have been greedy. Oh well, you make nothing. Negative
4 Yes
5 Yes Thanks For Nothing. Negative
6 Yes It would have been better if you had chosen D. I was going to split $0, so you would no gain. But $4 is better than nothing. So I decide to go with it. Have I been the divider, I would have chosen D. Negative

In the Offer column, the first number is the proposer's percentage share and the second number is the responder's percentage share. As described in the experiment's instructions (Supporting Methods), “D” stands for an equal-split offer and “A” stands for an offer of 10% to the responder (so 90% to the proposer). The last column shows whether the message is classified as expressing positive or negative emotion or is neutral (i.e. neither positive nor negative).
