I could be confident about my video game prowess and that'd be sexy to a female? Does not compute.

I don't understand this thing about confidence. Studies have shown that those who don't consider themselves incompetant are actually more incompetant than those that do. If you never doubt or are unsure of yourself - it is hard to be sure you're doing the right thing in this world - you may indeed be incompetant. Doubting yourself is a sign of intelligence.

I guess I can see this from a female's point of view. Women wish for protection, and an incompetant man is much more likely to start a fight due to his confidence to protect an ideal. The competant man considers, "Maybe I was wrong," and ends up coming off as the weaker of the two.
