At least for the "top 5% of men" thing, it's an oft-repeated meme on this forum.

In fact, it gets repeated so frequently in threads/topics like this one, that I wonder if the true origin of this "statistic" is in fact some of the... more interesting corners of Reddit/4chan.

OkCupid's blog posted similar statistics back in the day.

Can you link to some?

Run your own experiment if you don't believe me. On the Internet, nobody knows you are a dog. Burner SIM cards for verification are cheap too.

It is indeed true. Just go on a Tinder as an average man and see what you get.
