In a shocking study published in 2006, Don McCabe of Rutgers University and fellow researchers found that MBAs cheat more than other graduate students in the U.S. and Canada. This week’s portion of the HBR Debate on “How to Fix Business Schools” focused in on the problem of ethical lapses among business students and what to do about it. In the opening round, Professor McCabe agreed with senior editor Julia Kirby that the self-selecting personality that goes for an MBA already carries within itself the potential for iffy behavior.
