According to many articles that's a common misconception - that younger people empowered by Tinder can bang each other more and casually.[1] From my own anecdotes Tinder is actually a hindrance, since it creates a picture-oriented, extremely competitive environment where lack of physical attractiveness effectively shuts down the world of dating to the majority of men and women who aren't 8s, 9s, or 10s.[2]
I mean, on the net you'll often hear stories about kids scoring big but that's survivor bias. You don't hear anything from those who didn't bang.
