Simply because the immediate reaction to the Google Memo concentrated on sex differences I gathered together some posts on sex differences, showing that the sexes differ somewhat in their abilities: not very much, but enough to make a difference at the extremes, and it is the extremes which make a difference to technology based societies, and to a technology dependent world. I left out any mention of the notion that a “diverse” workforce is better than …… better than a workforce selected purely on ability to do the task in question. My mistake, which I will try to repair now.
I wondered, some years ago, what evidence there was for the proposition that diversity was a good thing. I would like to collect more proposals, because the ones sent to me proved unconvincing. You may have heard a claim that having women in the workforce boosts profits by 40%. This turns out to be a misunderstood joke.
Now to the general claim that having women in a group boosts anything, or that having a variety of intellectual levels in a group boosts anything. That was taken apart in a set of experimental studies by Bates and Gupta.
My conclusion was:
So, if you want a problem solved, don’t form a team. Find the brightest person and let them work on it. Placing them in a team will, on average, reduce their productivity. My advice would be: never form a team if there is one person who can sort out the problem.
Perhaps Damore was a guy who could sort out problems, until the last problem, that is.
I repeat my January 2015 request: if you have any good studies showing that having a sexually or racially diverse workforce boosts profits over a workforce selected on competence alone, please send me send them to me in a comment to this item.
