Past adversity protects against the numeracy bias in compassion.

Past research has suggested that one problematic limitation of compassion is its seeming resistance to increase in response to growing numbers of targets in distress. This insensitivity to numeracy results in the dampening of compassion when faced with mass suffering. Given that emerging evidence suggests that facing past adversity in life may foster compassion and a general prosocial orientation, we explored whether those who have experienced greater adversity show a resistance to this numeracy bias. In a series of 4 experiments, we demonstrate not only that those who have experienced greater adversity readily overcome the numeracy bias in compassion, but also that beliefs regarding their ability to be efficacious in helping others underlie this link. Of import, we also show that direct manipulation of such efficacy beliefs can remove the numeracy bias in compassion typically found among those who have not endured significant life adversity. Finally, we explore the ability of adversity to engender prosocial donations to those in need via mechanisms involving compassion and efficacy beliefs.
