Tinder would be able to counter a little this by showing the % that the other person swiped right. Women (and I guess Men) would be able to filter out those who swipe right 80%+ of the time... (I've not used it - maybe this already show this?)
In a system as shallow as Tinder it's often hard to find reasons to swipe left. You're allowed a handful of pictures and a few words about yourself. Everyone puts their best foot forward, selecting their most attractive pictures and saying little of substance about themselves in the tagline. Unless someone's appearance is unattractive to you don't really know enough about them to make a judgement either way. It seems…
I don't think I've swiped right even 20% of the time. Wonder if you can extract the stats from the iOS backup files...
