I could tell you that without a "research study". And any of my grandparents were also aware of it.
These kind of studies leave me a bad taste. It's as if they ran out of funds and want to produce something entertaining that sells stories and that looks like real research.
It also promotes sexism. I mean, what would be the natural conclusion coming out of such a study? Stay away from beautiful women? Don't hire them because you'll go nuts?
> Unless they fake the data, researchers do not have control over the results.
Yes they have.
In any statistic, you can introduce bias (many times without even knowing), the most common one being selection bias.
For example, I'd bet that the results for this research done on men coming from fields that are male-dominated (like engineering, finance), are totally different from the results of men coming from female-dominated fields.
