Ultimatum rejection
rejection rate or minimum acceptable offer
Willingness to destroy surplus rather than accept an unfair split. A fairness-and-status task.
The ultimatum game is the workhorse of social neuroendocrinology. Rejection is not 'aggression' in any simple sense; it can be a status-maintenance move. Exogenous T results disagree across labs, sexes, and belief-about-treatment designs.
Also called ultimatum game, fairness punishment.
