A fascinating three-part series from Freakonomics Podcast on commercial whaling, which had
this segue on how racial diversity both negatively and positively impacted whalers performance. Turned out, that racially homogenous crews outperformed diverse ones, at least in the first voyages, as incidence of internecine conflict were lower, before going on to outperform them in later voyages as the crew members worked out how to get along. Education and entertaining listen.
