Another thing too is sample size.
Good looking dudes are more likely to get approached by women who approach. And those women are usually more narcissistic and tend to have certain aint shyt personalities. A LOT of fat/unattractive women are the boldest too, dimes don’t go out of their way to approach.
These women are also used to approaching other handsome dudes who are also getting approached by a lot by the same types of women, so they’re more likely to have STDs.
All that glitters
Benefits don’t really exist too much in cold approach apart from women giving you a bigger time window and being less lenient if your conversation sucks. But that’s all temporary.
