Do Bullies Have Better Self-Esteem? Evolutionary Psychologists Say Yes (But Their Study Says No)
I know I said I was going to post this yesterday, but after the video was edited I noticed I misspoke in a way that was minor but bothered me, so we had to reshoot and edit. I think the final product is better, anyway, so it was worth it!



A new study claims to show that bullying is not a learned behavior. Evolutionary psychologists from Simon Frasier University say they’ve found evidence that it’s an adaptive trait: that bullies have better mental health, which leads to more sex, which leads to babies, who are also bullies. Baby Bullies, the hot new reality show debuting this fall on TLC!

The idea that bullies are literally born that way could have a tremendous impact on how we treat the serious problem of adolescent bullying, it there were any evidence it were true. But there isn’t. Not even in this study.

To the researchers’ credit, they admit their sample size is small enough that this should only be a preliminary study, but let’s be exact: they looked at 15 bullies, 10 victims, and 11 bully/victims who had been both bullied and been bullied. There were 97 kids who they called “bystanders” because they had neither bullied nor been victims. All the kids were 13 to 16 years old, and all of them were in one suburban Canadian middle school.

Each kid filled out a survey, which the researchers used to determine their levels of depression, self esteem, social status, and social anxiety. And here’s the crazy part: the researchers found there was no statistically significant difference on any of those four characteristics between bullies and “bystanders,” or between bullies and victims.

So if bullies don’t have better mental health than everyone else, guess what that means? This study absolutely, positively does not show that bullies evolved because they have better mental health.

That seems obvious, and yet I’m still seeing this study in the media claiming to show the opposite. That’s because the researchers did find a small but statistically significant difference between bullies and bully/victims. So basically, they split bullies up into two groups: one who had never been bullied before, and one who had. They found that bullies who had been bullied were worse off than bullies who hadn’t been bullied.

Okay, no shit?

Even then, though, they didn’t show cause and effect. So they have no way to say whether the bully/victims have lower self-esteem because they had been bullied, or if they were bullied because they have lower self-esteem.

The researchers also didn’t examine anyone’s DNA or even talk to their parents, so even if their results did show what the headlines are claiming, they still couldn’t support their stated hypothesis that “adolescent bullying is an adaptive behavior derived from evolution.”

So to recap, a study that claims to show evidence that bullying is an adaptive trait because bullies have better mental health and social status actually showed that bullies are about the same as everyone else, and it didn’t even come close to saying anything about human evolution.

Why this was even published, let alone covered in the media, is absolutely baffling to me. To help any other outlets that want to cover this piece, I’ve helpfully rewritten the abstract to be less misleading: In this study, researchers identify 11 kids in a suburban Canadian middle school who probably need help with their depression. The end.
