> One explanation might be that it’s an expected effect of the blurring of social boundaries today. In the past, if the size of your community was finitely bounded (like a village, or an aristocratic social class), people didn’t enter or exit these communities as frequently. Under these conditions, sanctions are probably still effective, because members of the community want to be liked and accepted. This is the center thesis of the article, we haven't evolved beyond our evolutionary physical bounds. We look at likes of Kardashians/Paris Hilton/Kanye and react with knee jerk reactions rooted deep in our biology. But it doesn't matter. Tribes exist in ways we can't see or touch, and the "shameless" understands how to harness that power.
