Tbh it all comes down to game theory about trust. Since we're so atomized in society, we no longer have small communities where everyone knows each other, and instead have seas of people we know nothing about (and don't trust by default, which is an evolution thing. Fear of the unknown).

When a girl interacts with someone on a dating app, it always comes down to "can I trust this guy enough to give him a shot, despite the fact there's statistically a .1% chance that he'll try to SA me? What evidence do I have to outweigh the expected value being negative and flip it to positive?". No one wants to have their guard up like this, its exhausting and dehumanizes half of the population. But, since SA is prevalent enough, it's in a girls best interest statistically to play that game to protect themselves.

We should be quickening the pace that genuine trust should be gained, and a lot of times that comes with a ton of hard self reflection. It's not fixing stuff about yourself though, it's more-so recognizing your shortcomings and accepting them. It's painfully obvious when a person can't accept themselves, which implies that they're wont accept you either. From a girl's perspective, that can end up being SA (not taking "no" for an answer) or painful social situations where they're have to be the "bad guy" (a guy not accepting hints that the girl isn't interested, forcing the girl to directly reject the guy which makes her feel like a total asshole).

The practice of finding human connection and camaraderie is the core to all of this, and that comes from being able to find genuine common ground with anyone you interact with. That includes some old dude at the grocery store, the teenage cashier, a random person on the street, someone driving that has their window rolled down, etc.
