I find Instagram does wonders, it added social proof to my online and real dating.
I even pull from IG having 3 dates 2 lays.
Linked Tinder > IG has created social proof there as well. (Most of my Tinder dates/lays checked out or I referred to my IG)
out on a real date, show her your IG... proof of your travels, status, view on life etc. My IG has upped my perceived game 100% and added unmeasurable social proof
Actually... from chatting to a 25yo HB8.5 lawyer from China, who was my seat mate on a flight, showing her my pics etc on IG... she was holding my hand by the time we were ready to l and... all Ican say is that you can add social proof from social media.
