I have huge doubts about the study. In cinema, theatre, sure, you need physical presence, but engineering... I don't believe Von Newman would have needed presence to impress other people.
Another very important thing is that there are very important differences between sexes. The most physically attractive man in the world without the proper attitude and without leadership and success is nobody.
I am what is called a sigma male. I was never interested in power, dominating others, being the boss. Women prefer ugly and short people if they are leaders to tall and beautiful man that are not social.
In fact, if you get uglier as you age but get more successful, you will receive way more attention. If you command a group of people, run a company or are a big boss, women will get in love.
Also, if you are tall and beautiful, men will get envious of you.
