On Thursday's AU we revisit our conversation with Jennifer Jacquet, author of "Is Shame Necessary? New Uses for an Old Tool."Robert Sapolsky (author of Monkeyluv) says: "In the age of Anthony Weiner and Miley Cyrus, shame seems an antiquated concept-a quaint tool of conformity-obsessed collectivist societies, replete with scarlet letters and loss of face ..." Jacquet says that in recent years, we as consumers have sought to assuage our guilt about flawed social and environmental practices and policies by, for example, buying organic foods or fair-trade products. Unless nearly everyone participates, however, the impact of individual consumer consciousness is ineffective.
