That's funny at first glance but it might be more accurate than we would like to admit. Maybe there were a lot of below average men (compared to the general population) on OKC when that study was conducted
Actually, the OkCupid founders used their own pictures and got nailed as significantly below average. <chuckle>
They really weren't. If anything, they were probably a bit above average.
Although, there is one thing that might have contributed back in the day. Female users of online dating might have been concentrated in tech areas. Being a rare female in a male dominated ratio area causes a highly skewed estimate of how attractive you really are.
