Organisational psychologist and professor of management at the Wharton School, University of Pennsylvania.
Give and Take presents evidence that people who default to helping others cluster at both the bottom and the top of performance distributions, and identifies what separates the two groups - directly useful for anyone designing incentives or picking partners. Think Again and Originals cover how people revise beliefs against new evidence and how unfamiliar ideas get championed inside established organisations.
