Here’s a more scientific example of how this tendency works. Two psychologists, Peter Ditto (of the University of California, Irvine) and David Lopez (founder and CEO of iAnalytics Statistical Consulting), told participants that they would take a test to determine whether they had a dangerous enzyme deficiency. For the test, participants had to put a drop of saliva on a strip and then wait for the results. Some learned that the strip would turn green if they had the deficiency; others learned that green meant they did not have the deficiency. The strip wasn’t a real test — it was simply a piece of paper that ever changed its color. The result? Participants who hoped to see the test strip turn green as evidence that they didn’t have the deficiency waited much longer than those who hoped not to see it turn green. That is, people waited more patiently for data when they believed the data would reassure them than when the believed it would scare them.
