The most important skill in science or self-improvement is noticing the unexpected.

If I could ensure that kids come away from science class with one thing only, it wouldnt be a set of facts. It would be an attitudesomething that the late physicist Richard Feynman called scientific integrity, the willingness to bend over backward to examine reasons your pet theories about the world might be wrong. That is the idea that we all hope you have learned in studying science in school, Feynman said in a 1974 commencement speech. We never say explicitly what this is, but just hope that you catch on by all the examples of scientific investigation.
Teaching that spirit is easier said than done. The hardest thing is convincing teenagers they can be wrong, a high school science teacher from Phoenix lamented to me recently in a conversation about scientific integrity. But to be fair, its not just teenagers. Were all captives of one of the most well-established errors in human reasoning, called confirmation bias: our tendency to focus on evidence that confirms our prior expectations. Once our minds alight on a theory, our impulse is to reassure ourselves its true, not set out to disprove it.
For example, researchers has demonstrated that our perception of a speaker depends on whether weve been told ahead of time that hes confident or shy. Our judgment of a childs academic skill depends on whether weve been led to believe that shes from a rich family or a poor one. When we serve on a jury, we quickly form an impression about whether the defendant is guilty, and then disproportionately interpret new evidence as supporting that impression.
In other words, we need to actively look for signs that our assumptions are wrong, because we wont do so unprompted. One such sign, scientists have suggested, is the feeling of surprise. Brains are continuously making predictions, psychologist Daniel Gilbert explains in his book Stumbling on Happinessabout how a friend is likely to react when you greet her, about what will happen after you knock a glass off the table, even about what sort of word youre going to see at the end of a sentence. Were generally not conscious of those predictions, until the world violates them. Surprise tells us that we were expecting something other than what we got, even when we didnt know we were expecting anything at all, Gilbert says.
