Why is it that some people are much better at turning their thoughts inward and reflecting on their decisions than others? The answer, neuroscientists say, may come down partly to differences in brain structure.
Fleming noted that introspection isn't the same as knowing the correct answer.
"For example, if you're a contestant on a game show and you're uncertain about your answer, you might choose to ask the audience for help. That kind of introspective knowledge is different from your basic ability to make the right decision."
