You're reading research that says they're geniuses? As far as I know lack of self-control is the main factor.

https://pmc.ncbi.nlm.nih.gov/articles/PMC8095718/ (see "Self-Control as Criminality" although it has a lot of caveats)

The other two are "being a young man" and lead poisoning, which are both versions of being dumb.

I didn't say this

Re the rest. Thanks. I had implicitly assumed we were talking about financial or white collar crimes rather than all crimes. In other words the types of crimes people generally assume that richer people commit (insider training, tax evasion, wage theft, etc.)

I think you are correct in the most general sense of "all crime"

Criminality seems to peak around 85IQ where people are smart enough to commit crimes but stupid enough to decide to commit them and not smart enough to get away with them.
