Anecdotal evidence is an informal account of evidence in the form of an anecdote, or hearsay. The term is usually used in contrast to scientific evidence, especially evidence-based medicine, which are types of formal accounts. Anecdotal evidence is often unscientific because it cannot be 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.) The problem with arguing based on anecdotal evidence is that anecdotal evidence is not necessarily typical; only statistical evidence can determine how typical something is. When used in advertising or promotion of a product, service, or idea, anecdotal evidence is often called a testimonial.
