The post was called The 4 Big Myths of Profile Pictures.
Since Ok Cupid published their data in support of not smiling in pics, the tip has been quoted as gospel truth on dating advice blogs, PUA podcasts, dozens of dating subreddits, forums, everywhere.
We are not saying take "glamour" shots or posed studio shots, because they won't reflect the relaxed you.
You can have everything going for you -- great job, no kids, never married, and sporting an appropriate number of teeth -- and one bad shadow, receding hairline, or misplaced background can render you undateable with one swipe. Researching profile photos has surfaced bizarre information, like the fact that the most popular guys show the left side of their faces and demonstrate pride.
Or that the most-matched women appear happy and (perhaps unsurprisingly) show some skin.
They use out-of-focus [photos], sloppy clothes, inappropriate facial expressions, bathroom selfies (with urinal behind them!
), bad angles -- [images are] too close up or too far away, taken below or above in unflattering ways, or too dark or light.
