One of the biggest turn offs for women is when a man can't admit that he made a mistake or that he was wrong in an argument. If you drove around for hours because you refused to ask for directions and you still can't admit that you had no idea where you were going, it's not going to look great in front of the woman you're with. If you argued and argued about a fact and the internet proves you wrong, simply admit she was right instead of finding obscure loopholes.
You may feel like you lose a bit of pride when you admit defeat. But trust us, it is far more attractive than insisting you're right when you so clearly aren't. If this is a problem for you, start practicing saying "you're right, I made a mistake."
