seniors, 0 percent rated themselves below average in “ability to<br />

get along with others,” while 60 percent put themselves in the<br />

top 10 percent (presumably not all were from Lake Woebegone).<br />

And according to a 1997 U.S. News & World Report study on<br />

who Americans believe are most likely to go to heaven, 52 percent<br />

said Bill Clinton, 60 percent thought Princess Diana, 65 percent<br />

chose Michael Jordan, 79 percent selected Mother Teresa,<br />

and, at 87 percent, the person most likely to go to heaven was<br />

the survey taker!<br />

Princeton University psychology pr<strong>of</strong>essor Emily Pronin<br />

and her colleagues tested a bias called blind spot, in which<br />

subjects recognized the existence and influence in others <strong>of</strong><br />

eight different cognitive biases, but they failed to see those<br />

same biases in themselves. In one study on Stanford University<br />

students, when asked to compare themselves to their peers on<br />

such personal qualities as friendliness and selfishness, they predictably<br />

rated themselves higher. Even when the subjects were<br />

warned about the better-than-average bias and were asked to<br />

reevaluate their original assessments, 63 percent claimed that<br />

their initial evaluations were objective, and 13 percent even<br />

claimed that they were originally too modest! In a second<br />

study, Pronin randomly assigned subjects high or low scores<br />

on a “social intelligence” test. Unsurprisingly, those given the<br />

high marks rated the test fairer and more useful than those<br />

receiving low marks. When asked if it was possible that they<br />

had been influenced by the score on the test, subjects responded<br />

that other participants had been far more biased than they<br />

were. In a third study in which Pronin queried subjects about<br />

what method they used to assess their own and others’ biases,<br />

she found that people tend to use general theories <strong>of</strong> behavior<br />

when evaluating others, but use introspection when appraising
