The association between trait compassion and third-party altruistic behavior after an unfair dictator transfer.

<p><b>a)</b> In the Helping Game, individuals who report greater compassion give more to the recipient after an unfair interaction (< = 25%). Including the two “extreme altruist” outliers in Helping Game responses, the correlation remains significant (<i>r</i>₈₉ = 0.214, <i>p</i> < 0.05). <b>b)</b> In the Punishment Game, trait compassion is not associated with punishment behavior after an unfair interaction in the full sample. However, within Punishers (individuals who decided to punish at all and spend > $0, indicated by black shaded circles), those who report greater compassion decide to punish less at trend level. ^†<i>p</i> < 0.1, * <i>p</i> < 0.05
