[*******#000000][FONT=sans-serif]The expression anecdotal evidence
refers to evidence
from anecdotes. Because of the small sample, there is a larger chance that it may be true but unreliable due to cherry-picked
or otherwise unrepresentative of typical cases.
[*******#000000][FONT=sans-serif]It is considered evidence, although often dubious if accepted often because it is the only evidence we have. However it may itself be true and verifiable.[/FONT][/COLOR]
[*******#000000][FONT=sans-serif]The term is often used in contrast to scientific evidence
, such as evidence-based medicine
, which are types of formal accounts. Some anecdotal evidence does not qualify as scientific evidence because its nature prevents it from being investigated using the scientific method
. Misuse of anecdotal evidence is a logical fallacy
and is sometimes informally referred to as the "person who" fallacy ("I know a person who..."; "I know of a case where..." etc. Compare with hasty generalization
). Anecdotal evidence is not necessarily representative of a "typical" experience; statistical
evidence can more accurately determine how typical something is.
