Figure 3. Responses on dictator and ultimatum game for low and high secondary psychopathy groups.

We found that in both the dictator game and the ultimatum game, participants in the high scoring secondary psychopathy group offered smaller amounts to members of the out-group relative to the in-group. However, participants in the low scoring secondary psychopathy group offered similar amounts to both members of the in-group and the out-group across both the dictator game and the ultimatum game.
