“This decision study was based on 566 real business decisions made by 184 business teams in a wide variety of companies from July 2015 through June 2017. […] The study was able to measure when teams made better decisions by tracking how often the decision maker changed their mind based on the input of the team. […] Decision makers changed their minds based on team feedback for 66 percent of decisions overall […] The impact of different team compositions was compared to this average.”

The results are as follows (probability of the decision change, number of experiments, P-value):

  All-Male                         58% 95 0.07
  Overall                          66% 566 -
  20+ Year Age Range               72% 127 0.13
  2+ Office Locations              72% 240 0.04
  Gender Diverse                   73% 217 0.05
  Geographically Diverse           75% 117 0.04
  Gender Diverse, 2+ Locations     79% 173 0.0005
  Gender Diverse, 20+ Yr Age Range 80% 94 0.005
  Gender, Geographically Diverse   87% 69 0.0002
“Decision results were measured 2-3 months after the fact by asking the decision maker to review the decision expectations written at the time the decision was made and compare those expectations to the actual results. […] we found that male decision makers inflated their decisions results by 7 percent compared to females. Also, after controlling for other factors, the study found that mixed gender teams are 13 percent more likely to miss expectations when following through on decisions compared to all-male teams.”
