Two games about trust and fairness. Hunt the stag together, or take a sure hare. Accept a tiny share, or reject it and leave both of you with nothing. A higher percent is a fairness-and-assurance lean.
About this test
Rousseau's stag hunt, revived by Brian Skyrms, is a coordination game: both hunters do best if both go for the stag, and each does fine alone if they take a hare. The risk is trusting the other hunter. The ultimatum game (Güth, Schmittberger, and Schwarze) gives one player a pot to split. The other can accept or reject. Rejection leaves both with nothing. Standard theory says accept any positive crumb. Real people often reject starkly unfair offers. Fehr and Schmidt model that as inequality aversion. These items are original. The percent rises with assurance-sensitive cooperation and with refusal of insulting splits. It is not a kindness score.
Question 1 of 11
What this test asks
When mutual trust would pay us both more than either can get alone, I am willing to play the cooperative part.
If I have no reason to think you will hunt the stag, I take the hare I can catch alone.
I look for a promise, a pattern, or a signal before I leave the safe choice.
I would share information that helps us coordinate, even if I could grab the safe prize a minute earlier.
I can forgive one missed signal and try the cooperative hunt again.
I would rather we split a gain evenly than I take a larger gain that leaves the other person with almost nothing.
In a take-it-or-leave-it split, I accept any offer above zero. Something is better than nothing.
I would reject an offer that gives me a little and the other person almost everything, even though rejection leaves both of us with nothing.
If we produced a pot together, a roughly even proposal is the one I start from.
The other person's disappointment is not my problem if the rules allow my offer.
I treat a very unequal offer as an insult to be answered, not only as a number to be banked.
