I'm above the average looking guy. When I added my picture to LinkedIn the amount of spam increased substantially.

People are really biased creatures. Usually the intent is not malicious, but rather caused by tribalism, evolution, empathy, mirror neurons etc.

One example is ageism, which is actually a systematic bias. For examplem to be a president you have be 35 or older. Let's imagine we created a perfect candidate in a lab which is 29. She's creme de la creme. And we have abolished this law.

No dice. She would not win.
