✦ Synopsis


We hypothesize that sharing a birthday is sucient to create a unit relationship. Two studies demonstrated that individuals cooperated more in a prisoners dilemma game when their (®ctitious) opponent shared their birthday. They also reacted more negatively to betrayal and were less sensitive to relative gains for self versus other.
