Brief empathy interventions online can decrease but not increase empathic tendencies.

People often feel less empathy towards outgroup compared to ingroup targets. Overcoming this intergroup empathy bias is important for fostering positive intergroup relations. In five pre-registered and high-powered online studies (n = 4776 (745/745/1056/1236/994)), we attempted to replicate and generalize motivated empathy interventions that previously have made people more empathetic and prosocial towards outgroup targets. Using both between- and within-subject designs, self-reported empathy measures and factual monetary donations, we examined the effects of several brief interventions. The interventions targeted avoidance motivations based on beliefs about the un/limited nature of empathy or approach motivations based on beliefs about empathy's malleability or normatively desirability. Across studies, we tested the interventions in several in- and intergroup contexts, using both novel and preexisting stimuli. In general, interventions failed to increase empathy or prosocial behaviour. Instead, inducing beliefs about the limited nature of empathy often reduced participants' empathy. Motivating people to withhold empathy may be easier than motivating them to increase it.
