We all know people who are highly intelligent but not very smart. These people get good grades in school, ace a lot of tests, and often succeed professionally. But they nevertheless hold irrational beliefs and do a lot of foolish things. Such people almost certainly have high IQs, but IQ scores do not reflect their particular form of cognitive deficit. Indeed, these people seem to be unable to think and act rationally despite their high intelligence.
University of Toronto psychological scientist Keith Stanovich has a name for this disability. He calls it “dysrationalia,” and he has spent the last several years trying to define the nature of this common deficit. He is giving an overview of dysrationalia at this week’s meeting of the Association for Psychological Science in Washington, D.C.
Consider this mental problem: “Jack is looking at Anne, but Anne is looking at George. Jack is married but George is not. Is a married person looking at an unmarried person?” Is the answer yes or no, or can the answer not be determined?
Most people conclude that they don’t have enough information to solve this problem, even though the correct answer — yes — can be arrived at fairly easily. The only person whose marital status we don’t know is Anne, so let’s try it both ways. If Anne is married, she is looking at unmarried George, so the answer is yes. If Anne is unmarried, and married Jack is looking at her, the answer is also yes.
