Question: The ultimatum game. In the “ultimatum game,” your partner gets $10, on the condition that it be shared with you. The partner makes you an offer. If you refuse, neither of you gets anything. So it’s to your advantage to accept even the unfair offer of $2 out of the $10. But many people refuse unfair offers anyway. This is evidence that our emotions can influence our economic decisions. Here are data on the responses of 76 subjects randomly assigned to receive an offer of $2 from either person they were introduced to or a computer:

We suspect that emotion will lead to offers from another person being rejected more often than offers from an impersonal computer. Do a test to assess the evidence for this conjecture.
