For two scholars representing opposing schools of thought, Daniel Kahneman and Gary Klein find a surprising amount of common ground. Kahneman, a psychologist, won the Nobel Prize in economics in 2002 for prospect theory, which helps explain the sometimes counterintuitive choices people make under uncertainty. Klein, a senior scientist at MacroCognition, has focused on the power of intuition to support good decision making in high-pressure environments, such as firefighting and intensive-care units.

In a September 2009 American Psychology article titled “Conditions for intuitive expertise: A failure to disagree,” Kahneman and Klein debated the circumstances in which intuition would yield good decision making. In this interview with Olivier Sibony, a director in McKinsey’s Brussels office, and Dan Lovallo, a professor at the University of Sydney and an adviser to McKinsey, Kahneman and Klein explore the power and perils of intuition for senior executives.
