I was gonna say that some of this is also probably sentencing bias. Subjectively the correlation seems too strong to not have some truth to it. I also have other data to support male = higher violence risk largely outside of perceptual bias.

As an example from my area of expertise, men complete suicide more often because they typically choose deadlier means (guns especially) vs women are more likely to attempt something like a drug overdose which is more reversible / leaves more opportunity for aborting the attempt. There's not a lot of room in those stats for perceptual bias, dead is dead and alive is alive. It's basically a known fact that men are more violent to themselves. I won't get too much into the stats of violence against others except to say that the statistical predictor tool I've used for that in institutional environments didn't use "male," it used "male under 30y/o."

On the other end of perceptual errors almost govern criminal sentencing. Entrusting a group of people to judge an event reduces some but not all of the perceptual bias, but certainly can't eliminate it. And I do also have my own subjective / experiential perspective that is similar but in some ways inverted to yours (but is also almost certainly occurring in a 100% different environment):

When I first started in my field I was told and found to be true that when you're breaking up a fight between men all you need to do is break eye contact. You get between them back to back with a coworker and if you can't block their sightline to each other with your bodies you shove one of them around a corner. And that's it. Within about 30 seconds they're in tension reduction talking about their feelings in that emotionally constipated way western men do ("he just made me so mad!"). Otoh I was told and found to be true that you let the women go at it until the entire code team arrives from your surrounding units because you're going to basically have to do a full restraint episode for each woman.

(Sorry I have lots of thoughts about violence it's actually kinda my area of professional expertise.)
