It's a silly concept and no one on the planet should lend any thought to it beyond "That's fucking stupid"
Anyone with any knowledge knows that human beings, success, and social interactions are UNBELIEVABLY complicated and that it's nonsensical to think they can be reduced to 2 simple categories. Or any number of categories.
Furthermore, even if we COULD simplify it like that, the order is all wrong.
Most success doesn't come as a result of dominant personality. There are plenty of dominant frat boys and rednecks that have done nothing in their lives. Confidence comes as a result of success.
In terms of women, you could argue that a dominant personality attracts, but again, a person who is successful with women becomes confident and thus more dominant.
Finally, in terms of the "born to win" concept, it's Nature vs Nurture and there is enough debate that it's impossible to definitively say either is more important.
