Excerpts:
Wall Street is one of the most male-dominated bastions in the business world; senior staff meetings resemble a urologist’s waiting room. Aside from issues of fairness, there’s evidence that the result is second-rate decision-making.
“There seems to be a strong consensus that diverse groups perform better at problem solving” than homogeneous groups, Lu Hong and Scott E. Page wrote in The Journal of Economic Theory, summarizing the research in the field.
A fascinating British study supports that conclusion with evidence from the drool of financiers.
One of the shortcomings of any system of men sitting in front of screens making financial bets was reported last year in the journal Evolution and Human Behavior, in case you missed your copy. That study found that men are particularly likely to make high-risk bets when under financial pressure and surrounded by other males of similar status.
As for women, their risk-taking was unaffected by this kind of peer pressure.
