Scientists Discover People Act More Altruistic When Batman Is Present (futurism.com) 63

Psychology Today reports: In a study conducted in Milan, Italy, and published in November 2025, the sight of a person dressed as Batman led to a nearly doubled rate of people giving up their seat to a pregnant woman. Over the course of 138 subway rides, researchers found that people who saw "Batman" standing near the pregnant woman were far more altruistic than those who did not.

Researchers are calling this the "Batman effect," suggesting a form of "involuntary" mindfulness may be at play. Noticing these subtle social cues appears to shift people's typical, automatic reactions. Most interestingly, 44 percent of the people questioned reported they did not even consciously register Batman's presence... The superhero costume serves as a visual nudge, pulling us out of our default, self-focused mode and into a more generous, attentive state.

More from Futurism: Batman showing up is just one — albeit striking — way of promoting what's called "prosocial behavior," or the act of helping others around you, via introducing an unexpected event, the researchers write. "Our findings are similar to those of previous research linking present-moment awareness (mindfulness) to greater prosociality," said study lead author Francesco Pagnini, a professor of clinical psychology at the Università Cattolica in Milan, in a statement about the work. "This may create a context in which individuals become more attuned to social cues."

    • That research sounds improbable.

      As whacky as the research sounds, theres precedents, albeit less funny ones.

      Back in the 1980s where I lived, supermarkets used to always stick cardboard cutouts of policemen around the shop, cross-armed and staring. Apparently those where really effective.

      Nobody actually thought it was a real policeman staring, but the psychological effect was enough that people felt too *observed* to actually go and do the crimes. I can only assume what this shows is it doesnt really matter what the authoritarian figure is , be he commissioner gordon, or batman, its enough to make people feel anxious about wanting to do good, or rather to be SEEN as doing good.

      As the philosopher foucault observed, panopticon doesnt work by the prison guards doing the discipline, but the discontinuous sense of being observed made the prisoners discipline themselves.

      • I've never seen any actual controlled studies showing those were effective. There's plenty of anecdotal evidence ("we put them up and a week later shoplifting had gone down") but no actual controlled studies, for example whether the shopkeepers were looking around a lot to see if anyone noticed the scarecop, which would have also deterred shoplifting. It's like the 1990s fad of putting bottles of water on your lawn to keep dogs away, that was a fad until people tried tracing down the source of the wisdom

        • No, actually theres plenty of studies. You have to look first if you want to know!

          Look up "watching eye effect supermarket" in google scholar or your academic search engine of choice. Theres literally hundreds of studies.

          • The watching-eye effect is, as a previous posted pointed out, related but no more, it's very different from putting up a life-sized scarecop. There's also been several recent studies which failed to find any effect for watching-eyes, e.g. this one [nih.gov]. So I don't think watching-eyes counts as evidence for scarecops.

      Those are probably on the TANSTAAFL combined with "Pay it forward" level - letting someone else pay. But for those that get the help it could be worth a lot compared to their income.

      I have seen a few of the recoveries and they range from complicated to just giving advise to those that got stuck to let them work their vehicles free themselves. Teaching others how to get out of trouble is worth a lot.

  • Sometimes, social scientists who are under pressure to publish, anything, no matter what, to increase their publication count, will propose stupid experiments, that don't cost much to do, do not measure any intrinsic behaviour of humanity, and can be modified trivially to generate alternative papers. The trick is to brainstorm and try out a lot of these, until the p-value finally fits.

      Sometimes, Slashdot posters who are under pressure to publish, anything, no matter what, to increase their publication count, will make stupid comments, mentioning terms they have vaguely heard about, without any real thought as to whether they apply.

      P-hacking involves researcher degrees of freedom and the ability to find some signal for "something" in a bunch of data by varying how the the analysis is performed after the events themselves.

      That does not seem a relevant at all in the context of this particular study, which uses a very simple method and measure for what it is testing and whose methodology was pre-registered [clinicaltrials.gov] before it was done.

        too many heard about p hacking on a podcast and think its a magical "get out of any statistic" card

      • Sorry, you seem to think your link invalidates the point. It does not, but you're welcome to make up a strawman and answer it. I would dress up as a batman to keep you honest, but in my culture we don't know what that is. Thanks for playing, though.
        • The only "point" your post makes is that you don't know what p hacking is.

          If you have some other criticism of the study, then putting "p-value hacking" as the subject is your error not mine.

        Coincidence, perhaps, how neatly that intersects with your observation.

    • The study also doesn't indicate whether it was the Adam West Batman or the movie one. I think that would confound the experimental controls.

      Why be so negative? Some people might have been motivated by seeing an example of altruism in front of them. Despite how I personally feel, not everything is negative. That is also true regardless of how you personally feel.

    If someone is dressed up in a Batman suit, more people will assume that it's being recorded and will also more likely be posted online. If they will be recorded and posted online, then people will "behave" better for fear of repercussions.

    It's like that old study about what was the ideal lighting that will get workers to work harder. In the end, it wasn't the lighting that made them work harder, it was the constant monitoring that was known that their bosses would see that made them work harder.

      My guess is it is more likely to be an artefact of increased attention rather than an actual increased tendency to be pro-social.
      Ie, people on average are x% likely to give up a seat for a pregnant woman if they are actively aware, but in many cases people on public transport are "zoned out" so the actual rate of people giving up a seat is lower.
      The "Batman" may just be something somewhat unusual that increases people's awareness of their immediate surroundings rather than making them more pro-social.
      An interesting follow up would be to try things that are "unusual" and attention level raising, but are somehow neutral and free of the sorts of symbolism that are attached to Batman.
