Superhero films can encourage prosocial behavior, new study finds

A new study published in The Journal of Psychology suggests that superhero films, despite often depicting violence, can promote prosocial behavior — actions meant to benefit others, such as sharing or helping. By showing a specific scene from the 2016 film Batman v Superman, the researchers found that viewers who identified with Batman or believed his actions were morally justified were more likely to help others in a subsequent task.

While previous research has shown that prosocial media can encourage helpfulness and cooperation, violent media has typically been associated with increased aggression. Superhero films, a genre with widespread popularity, often mix these two elements. The researchers wanted to explore how these films might affect viewers, particularly in terms of empathy and moral reasoning, which could influence whether viewers engage in prosocial behavior despite the violence on screen.

The study involved two experiments, each with 200 Brazilian participants, who were randomly assigned to either an experimental group or a control group. The experimental group watched a 3-minute and 47-second clip from the movie Batman v Superman, in which Batman fights multiple armed villains to rescue Martha, a captured character. This scene was chosen for its combination of violent action and a clear prosocial motive—saving a life.

In contrast, the control group watched a neutral video that featured colorful shapes forming various patterns. This video, which had no violent or prosocial content, was meant to serve as a baseline for comparison.

After watching the videos, participants were asked to complete a prosocial behavior task. They were told they were helping with another study by distributing pieces of chocolate to future participants who liked the treat. The number of chocolate pieces each participant allocated served as a measure of their prosocial behavior.

The researchers also measured participants’ levels of empathy after viewing the videos. To do this, they used a scale that assessed three different types of empathy: affective empathy (sharing another person’s emotions), cognitive empathy (understanding another’s perspective), and associative empathy (identifying with the character in the video).

In the second experiment, the researchers introduced an additional measure—moral justification. Participants were asked to evaluate whether the violent actions taken by Batman were justified. This was done using a series of statements such as “The main character’s actions were necessary” or “It was impossible to deal with this situation in any other way.”

In the first study, participants who watched the superhero scene reported higher levels of empathy than those in the control group. More specifically, viewers showed increased associative empathy — they identified more with Batman and his mission to save the hostage. This identification with the hero was the key factor that indirectly boosted prosocial behavior.

While participants in the superhero group didn’t give significantly more chocolate than those in the control group overall, the effect of the movie on prosocial behavior was seen through the increase in empathy. This suggests that feeling connected to the hero and understanding their motives could encourage viewers to be more generous and helpful in their real-world actions.

The second study revealed that moral reasoning also played a role in prosocial behavior. Participants who watched the superhero scene were more likely to believe that Batman’s violent actions were justified. This belief, in turn, was linked to higher prosocial behavior, as measured by the chocolate allocation task.

Essentially, when participants viewed the hero’s actions as morally right, they were more inclined to engage in helpful behavior themselves. The researchers theorized that the portrayal of superheroes as protectors and defenders likely led viewers to accept their violent actions as necessary for the greater good, which then translated into a willingness to help others.

In short, simply watching the superhero scene did not directly cause participants to behave more prosocially. Instead, the participants who empathized with the characters or believed the violent actions were justified were more likely to act in a helpful way afterward.

While the study offers valuable insights into the effects of superhero films, it is not without limitations. One limitation is the use of an online experiment, which may reduce the level of control over participants’ environments and behavior. For instance, distractions during the video could have affected participants’ responses. Additionally, the study only used a single method of measuring prosocial behavior (the chocolate allocation task), which may not fully capture the complexity of prosocial actions in real-world situations.

Another limitation is the sample size and demographic characteristics. The participants were predominantly young adults from Brazil, which may limit the generalizability of the findings to other age groups or cultural contexts. Future research could address this by replicating the study with different age groups and in various cultural settings.
