Nicholas Kristoff: “…In a thoughtful book published this year, The Life You Can Save, Professor Peter Singer of Princeton University … explores why we’re so willing to try to assist a stranger before us, while so unwilling to donate to try to save strangers from malaria half a world away.

…There’s growing evidence that jumping up and down about millions of lives at stake can even be counterproductive. A number of studies have found that we are much more willing to donate to one needy person than to several. In one experiment, researchers solicited donations for a $300,000 fund that in one version would save the life of one child, and in another the lives of eight children. People contributed more when the fund would save only one life.

“The more who die, the less we care.” That’s the apt title of a forthcoming essay by Paul Slovic, a psychology professor at the University of Oregon who has pioneered this field of research.

Yet it’s not just, as the saying goes, that one death is a tragedy, a million a statistic. More depressing, appeals to our rationality actually seem to impede empathy.

For example, in one study, people donate generously to Rokia, a 7-year-old malnourished African girl. But when Rokia’s plight was explained as part of a larger context of hunger in Africa, people were much less willing to help.

Perhaps this is because, as some research suggests, people give in large part to feel good inside. That works best when you write a check and the problem is solved. If instead you’re reminded of larger problems that you can never solve, the feel-good rewards diminish.” (New York Times op-ed)
