I think it&#x27;s a serious problem when more than half of society is denied a fair opportunity.<p>&gt; Yet US has done just ok with males (white and asian) doing this stuff. Ie better than anybody else in the world.<p>That doesn&#x27;t mean the US and others can&#x27;t do much better. Think how much talent is lost - more than half of it. There&#x27;s a shortage of talent in SV. There is much that needs to be done in the world.<p>&gt; Is there any proof that increased diversity has any effect<p>I&#x27;ve read about a lot of evidence that more diverse groups make decisions significantly better.
