I thought this has always been pretty obvious. It’s just human nature that makes people “judge” by appearances. As long as there is a face to face interview I don’t think someone could claim is not discriminating on appearance. It happens “naturally” and could go both ways but more often the “good looking” and “charming” is rewarded. It’s part of the “life’s not fair”.
Nah, gobs of people will insist to your face, despite direct evidence, that "I can look past it" when interviewing, or "I don't see color"
The world is made of HR departments and executive suites chock full of people who insist they are somehow special and immune to all the things we know about how fallible humans are at making decisions.
It's like how nearly everyone believes themselves to be an "Above average" driver, including the morons who get into an accident every single year because they text and drive constantly.
