Not his opinion but one could cite the report itself:
Diversity matters. Research shows that teams with more women members have higher collective
intelligence and achieve better business outcomes. Our survey shows that few teams are truly diverse
with regard to gender. We recommend that teams wanting to achieve high performance do their best
to recruit and retain more women, and improve diversity in other areas, too.
which claims having more women on the board has achieved better business outcomes.
Which is fine until you start digging and find out that they passed legislation in Europe forcing companies to be more diverse. That companies in Europe had the number of women on boards double in less than two years http://imgur.com/a/4sE2y despite a recession and stagnating economy.
Then they justify the economic "recovery" since the 2008 crash to that decision.
And now hiring more women is associated to economic growth.
You should hire and compensate people based on the value they generate. Instead companies are becoming political parties trying to reach diversity quotas to satisfy the local demographics and government policy du jour.
This has been going on for decades but there is nothing like government intervention to accelerate a disaster.
Read down. They cite several studies. To be honest, I was little weirded out by the implication that diversity and equitable gender distribution are synonymous. In fact there is only one-half sentence mentioning non-gender diversity - "and improve diversity in other areas, too."
