Anecdotal Evidence

Anecdotal evidence (/ˌænɪkˈdoʊtəl ˈɛvɪdəns/) is evidence that is collected in a casual or informal manner and relies heavily on personal testimony. The term is often used in contrast to scientific evidence, which is evidence that is collected through scientific methodology and rigor.

Etymology

The term "anecdotal evidence" comes from the Greek word "anekdota," which means "unpublished." It was first used in English in the 18th century to describe personal stories or experiences that were not scientifically validated.

Related Terms

  • Empirical evidence: Evidence that is based on observation or experience, not just on theory.
  • Confirmation bias: The tendency to interpret new evidence as confirmation of one's existing beliefs or theories.
  • Cognitive bias: Systematic errors in thinking that can affect the decisions and judgments that people make.
  • Hearsay: Information received from other people that one cannot adequately substantiate; rumor.

Usage

Anecdotal evidence is often used in the legal system, in personal narratives, and in journalism. It can be powerful and persuasive, but it is also subject to bias and unreliability. Therefore, it is generally considered less reliable than empirical or scientific evidence.

Criticism

Critics of anecdotal evidence argue that it is subject to numerous potential problems, including confirmation bias, cognitive bias, and the unreliability of human memory. They argue that anecdotal evidence should not be used to make broad generalizations or to form the basis of scientific theories.
