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?
Yet I hope the article is not being upvoted as startup advice: "Don't hire beautiful women."
Perhaps heterosexual men can also train themselves to think of beautiful women as people first instead of as sex objects primarily.
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.
