If that comparison sounds overwrought, consider the words of Denny Gioia, a management professor at Penn State who, in the early 1970s, was the coordinator of product recalls at Ford. At the time, the Ford Pinto was showing a tendency to explode when hit from behind, incinerating passengers. Twice, Gioia and his team elected not to recall the car—a fact that, when revealed to his M.B.A. students, goes off like a bomb. “Before I went to Ford I would have argued strongly that Ford had an ethical obligation to recall,” he wrote in the Journal of Business Ethics some 17 years after he’d left the company. “I now argue and teach that Ford had an ethical obligation to recall. But, while I was there, I perceived no strong obligation to recall and I remember no strong ethical overtones to the case whatsoever.”
