There is plenty of evidence for hiring discrimination of all sorts. Oceans of it. For example:<p><a href="http:&#x2F;&#x2F;www.nber.org&#x2F;papers&#x2F;w9873" rel="nofollow">http:&#x2F;&#x2F;www.nber.org&#x2F;papers&#x2F;w9873</a><p><a href="http:&#x2F;&#x2F;www.nber.org&#x2F;papers&#x2F;w5903" rel="nofollow">http:&#x2F;&#x2F;www.nber.org&#x2F;papers&#x2F;w5903</a><p>It happens in all sorts of industries and across a variety of axes. I&#x27;ve heard some argue that no, tech is different, that we&#x27;re special, special snowflakes. But they have no evidence to back that, just feelings that bias is something only other people do.
