"Don’t rely on self-nominations or self-evaluations"

I think this is the big thing that should be rallied around. This is prevalent, obvious, and hurts companies in more ways than just discrimination (not to marginalize that aspect).

Focusing on self-nominations means the most successful people aren't going to be your people best able to do the job, but people best able to 'play the game'. This is in fact not independent, but negatively correlated with skill. (Citation needed)
