Just seeing Batman inspires us, say psychologists, whose new research suggests that seeing the caped crusader increases an individual’s propensity toward prosocial behaviors.
The research, conducted on a Milan metro train, found that a sudden, unexpected interruption in our daily lives—in this case, seeing the famous DC Comics character—can break us out of the autopilot that typically governs our behavior, encouraging us to pay attention to the people around us and empathize with their needs.
Led by Professor Francesco Pagnini, the research was undertaken by researchers from the Università Cattolica del Sacro Cuore in Milan and published in NPJ Mental Health Research.
Prosocial Behavior
Actions that benefit those around us are called “prosocial behaviors,” an area that we hear much less about than their “antisocial” opposites. In new research focused on the positive side of life, Dr Pagnini’s team investigated how surprises, such as encountering someone dressed as Batman, bring people into the moment and encourage them to consider those around them.
“We conducted an experimental field study on the Milan subway,” Professor Pagnini explained, “observing the behavior of 138 passengers. In the first part of our test (control condition), an experimenter, apparently pregnant, boarded the train with an observer.”
The researchers say prosocial behaviors can stem from genuine altruistic empathy, egoistic guilt, or the pressures of internalized social norms. Instead of looking inward, the new work examines how external factors shift individuals toward prosocial behaviors.
Batman Metro Tests
In the control tests, the observer then noted whether passengers would get up to give their seats to pregnant women. The test then brought a second experimenter into the mix, this time dressed as the Dark Knight. This individual dressed as Batman would enter the train car from a separate door, as the pregnant woman had done.
The contrast between the results was stark. In the control, just 37.66% volunteered to give up their seats for the pregnant woman. While in the presence of Batman, however, this number almost doubled to 67.21%. Intriguingly, when participants were interviewed after the experiment, 44% of those who offered their seats in the experimental rounds reported not noticing the experimenter dressed as Batman.
Bringing People to the Moment
The results indicate that, even without being consciously aware of them, unusual events in our surroundings appear to play a role in prompting acts of kindness in public settings, and at significantly increased rates.
“Our findings,” Pagnini explained, “are similar to those of previous research linking present-moment awareness (mindfulness) to greater prosociality; this may create a context in which individuals become more attuned to social cues.”
The new research is unique Pagnini explains, because it reveals results that are the opposite of past work that focused on an intentional change in mindset, whereas the Milan experiment showed that a mere break in routine can change how we see the world.
“Unlike traditional mindfulness interventions that require active engagement, this study highlights how situational interruptions alone may be sufficient to produce similar effects,” Pagnini said. “This suggests a potential mechanism through which novelty and unpredictability promote prosocial behavior, strengthening theories linking attentional shifts to increased social responsiveness.”
“It is also possible that the superhero figure enhanced the relevance of cultural values, gender roles, and norms of chivalrous help, consistent with research on the ‘priming’ effect associated with superheroes: the figure of Batman could therefore play a prosocial priming role,” Pagnini concluded.
The paper, “Unexpected Events and Prosocial Behavior: The Batman Effect,” appeared in NPJ Mental Health Research on November 3, 2025.
