Document Summary

Induction is a pattern of reasoning in which one seeks to draw general claims from specific bits of evidence. When we discuss induction and other aspects of human reasoning, we will often be comparing: a descriptive account, telling us how reasoning ordinarily proceeds (including the errors, a normative account, telling us how we ought to reason. Note that induction drawing a general conclusion based on previous observations and experiences relies on memory. If memories are selective, incomplete, or distorted, then the validity of the induction will be questionable. I can always tell when someone is lying. Creative people are usually a little bit crazy. This year"s freshmen seem more mature than last year. Recall that a heuristic is a strategy that is reasonably efficient and works most of the time. In using a heuristic, we gain efficiency at the expense of more error.
