Passions Within Reason: The Strategic Role of the Emotions

TLDR: The authors showed that looking out for Number One may require that we look out for others, too, finding evidence in our emotional acts, like the blush on telling a lie, they can serve as hard-to-fake signals of a commitment to social values.

Abstract: The "Me" generation has justified itself by appealing to social scientists who see selfishness as the only rational basis for action. But what are we to make of selfless acts in business, personal life, even politics? In this provocative book, Robert Frank shows us that looking out for Number One may require that we look out for others, too. He finds his evidence in our emotional acts. Like the blush on telling a lie, they can serve as hard-to-fake signals of a commitment to social values. We recognize these signs; we know people we trust; and if we can identify trustworthy fellows we can reject those who do not merit our faith.
