Hey guys, this is just a little trick I've developed that works pretty well in my opinion for gauging interest.

It's very simple. Make eye contact, raise your eye brows. It's simple body language. If she's interested she might giggle, raise her eyebrows back, or give you another form of IOI. If she isn't into you she'll probably just look away or respond in a way that shows she isn't interested.

This can be implemented from across the room, or while you're talking to her. I don't know if it's confirmation bias but I do it a lot and I find that girls who respond positively end up being attracted to me, and the ones who don't weren't that attracted in the first place.

Another great thing about it is that it's really harmless. It doesn't make you look like a creep if it fails, and if it works you know you're in.

Just a little thing I thought I'd share as it has been working out for me, let me know what you think.
