Most men don't have self confidence to approach period.
Idk where yall get the idea that these 9s and 10s are not being approached but they are.
This is what we call a limiting belief.
I don’t think anyone said 9s and 10s aren’t being approached. Like you said, most dudes just don’t have the confidence to approach women regardless. But if you take a prime Adriana Lima vs a girl who’s a 6 or 7 and drop them in a park, the 6 or 7 is way more likely to get cold approached.
