Do you have evidence for increasing diversity helps?



The Impact of Gender Composition on Team Performance and Decision-Making: Evidence from the Field

http://www.econ.upf.edu/~apesteguia/Gender_Teams.pdf

"Looking across the performance distribution, we find that for undergraduates, three women teams are outperformed throughout... For MBA students, at the top, the best performing group is two men and one woman."

"The standard argument is that diversity is good and you should have both men and women in a group. But so far, the data show, the more women, the better."

"The optimal percentage for the gender balance of men and women on teams is 50:50. Neither men nor women flourish when in a minority on teams. When in a minority, women tend to network outside whereas men tend to become less motivated. Having a slight majority of women on teams (about 60%) improves the self-confidence of the team."

I think the evidence is pretty clear. Anecdotally, I've seen the best performance out of mixed teams. All men teams and all women teams generally don't work out so well.

Moreover, companies which have more female execs report higher earnings. They literally make more money as the number of women in senior management increases.[1][2]

However "if many stock speculators believed Kay and Shipman, firm stock prices would jump upon hiring more female execs, making most CEOS quite eager to hire more women execs. There would be a boom in female execs and Kay and Shipman would not have bothered to write their oped. Since that didn’t happen, I’ve gotta believe most speculators don’t believe those studies, and so I shouldn’t believe them either. If you think otherwise, go speculate."[3]

Here's your chance to put your money where your mouth is and rake in the returns, laughing at the sexists all the way to the bank.

> I think the evidence is pretty clear.

Uh? The 3 excerpts you quote say 3 different things.

Could you show me the differences? Those three excerpts seem to be saying the same thing to me.
