Does diversity help attain wisdom? Sometimes, it seems. Scott Page calls this the diversity dividend. Quantifying when and how it works is of interest to me. Possibly diversity and tolerance is not just an intrinsic moral good, but may pay literal dividends in terms of avoiding groupthink in your team. What are the conditions for this happy state? Dobbin and Kalev (2016) argue that punishing failures can be counterproductive, in favour of voluntarism and transparency, which might harness status psychology of the incumbent power brokers.
McKinsey report, Vivian Hunt, Dennis Layton, and Sara Prince: Why diversity matters:
While correlation does not equal causation (greater gender and ethnic diversity in corporate leadership doesn’t automatically translate into more profit), the correlation does indicate that when companies commit themselves to diverse leadership, they are more successful.
(They could possibly have done better than that mealy-mouthed correlation phrasing if they wanted, via causal analysis.)
Other random readings: Chris Dillow, diversity trumps ability.
The new Matthew Syed book (titled Rebel Ideas or Superteams depending where you are) apparently covers some of this material (Syed 2020).
