I mean “I’m about to pretend that ‘sexy’ and ‘good actor’ are binary variables centered to make the math super easy.” If you would like less pretending, read the Atlantic article linked by a thoughtful replier, since the author draws the nice graph to prove the general case.
I wouldn’t like less pretending and ‘sexy’/‘good actor’ being binary variables is fine with me (and I understand your comment overall), but still I don’t know what does it mean that the groups are equally full. (Equal size? That doesn’t follow from independence.)
Right, so I make the math-light but false assumption that casting directors will take above-average applicants, and also that you aren’t more likely to eventually become an actor if you’re sexy and can act well.
What do you mean by “equally full”?

If you mean “above median”, I see.
