What kind of conclusions if any can be made from anecdotal evidence?

With anecdotal evidence, it is typically the conclusion from one or even a group of people based on no scientific study or testing. Most of the time, anecdotal evidence is based on personal experience, which would be a fine way to start the scientific process—by asking questions about that experience.

What does an anecdote do?

Anecdotes – these are short accounts of a real event told in the form of a very brief story. Their effect is often to create an emotional or sympathetic response. An anecdote is usually used to help support a persuasive argument that the writer is putting forward.

What is anecdotal fallacy?

The Anecdotal Fallacy is committed when a recent memory, a striking anecdote, or a news story of an unusual event leads one to overestimate the probability of that type of event, especially when one has access to better evidence.

Why is anecdotal evidence persuasive?

A vivid argument would be more convincing than a more pallid one. Nisbett and Ross (1980) dub this the vividness effect. Following this line of reasoning, anecdotal evidence would be more convincing than statistical evidence, not because it is based on a single instance, but because of its higher imagineability.

What is the difference between anecdotal and scientific evidence?

Anecdotal evidence can be defined as testimony that something is true, false, related, or unrelated based on isolated examples of someone’s personal experience. While scientific evidence can be independently verified using the scientific method, anecdotal evidence cannot.

What is the problem with using anecdotal evidence to support a theory?

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.)

Why is anecdotal evidence frequently unreliable?

Anecdotal evidence is often unscientific or pseudoscientific because various forms of cognitive bias may affect the collection or presentation of evidence. For instance, someone who claims to have had an encounter with a supernatural being or alien may present a very vivid story, but this is not falsifiable.
