Empathy incites a stable prosocial decision bias

Area of Science:

• Neuroscience
• Social Psychology
• Behavioral Economics

Background:

• Empathy for suffering drives prosocial behavior.
• The persistence of empathy-induced prosociality after suffering diminishes is not well understood.

Purpose of the Study:

• To investigate whether prosociality driven by empathy for another's pain persists after the suffering decreases.
• To examine the neural mechanisms and stability of empathy-driven prosocial decisions.

Main Methods:

• Functional magnetic resonance imaging (fMRI) and drift-diffusion modeling were used to analyze participants' decisions in a social task.
• Participants allocated points to themselves and another person under conditions of frequent and infrequent pain for the other person.
• Behavioral and control studies were conducted to replicate findings and assess specificity to empathy.

Main Results:

• Empathy for pain induced a sustained bias toward prosocial decisions, even when the other person's pain decreased.
• Neural activation in the dorsomedial prefrontal cortex correlated with empathic concern and prosocial decision bias.
• The observed stability in prosociality was specific to empathy and not seen when driven by social norms like reciprocity.

Conclusions:

• Empathy for pain establishes a stable inclination for prosocial behavior that endures beyond the immediate reduction of suffering.
• The findings highlight the lasting impact of empathy on decision-making and social behavior.
• Dorsomedial prefrontal cortex plays a role in both empathic concern and the sustained bias for prosociality.
