Let's say every male is given the ability to telepathically know to what degree a girl finds him physically attractive (with a fairly decent accuracy rate).

This ability wouldn't grant that male any other knowledge other than how she feels about him physically in that moment.

So in theory wouldn't this make dating extremely easy for men? I feel like a lot of the talk throughout this forum is about how I can't approach her at x location cause she's working, I can't approach her in a library or I'll be creepy, don't wanna cold approach and be accused of harassment etc etc etc.

Wouldn't all that shit be corrected if you had this fictional ability and could telepathically see who is worth pursuing? Because the reality is if she finds you attractive any of the approach methods will work as long as you aren't very obviously being weird about it. I think a lot of guys see a girl that they're attracted to and auto-assume she's out of his league, when the reality could be the complete opposite, you just have no way of knowing. This ability would hugely decrease the fear of failure, as you'd already know the outcome and which girls aren't into to you.

The reason I'm going on this odd discussion rant is because I struggle with dating, and I struggle because I go into every interaction with women under the pre-conceived notion that she finds me unattractive which obviously saps my confidence in any conversation. I feel like if I had this ability and just knew from the outset, I'd be FAR more proactive in trying to escalate things to dates etc.

Who knows maybe Elon's brainchip will be able to compute girls every single movement and inform you if she's into you or not lol.... probably the only realistic incarnation of this idea.
