Women think "If he married a very attractive woman, then he must have things going for him other than what I currently see".
It's magic: you get lots of attention the moment you show you DON'T NEED their attention.
Yup—the manosphere teaches that women are generally social creatures who can be fooled by social “cues”. They are particularly vulnerable to the opinion of their “friends” or peers—so it is not good enough for a woman to be attracted to you, her friends must be as well.
That is why I tell young men to becomes “leaders” in whatever they are good at—they can become “mini-alphas” in limited social groups—even if they are not “real alphas”.
The body language other people give the “leader” is the social cue that women pick up on—even though most men would never even notice it.
