Anecdotal evidence

From WikiSynergy

Anecdotal evidence is evidence consisting of individuals' personal descriptions and experiences. Such evidence is often hard to verify. Because of this, it is often claimed that anecdotal evidence cannot be scientific evidence. This is not the case. Anecdotal evidence, if properly handled, can yield scientific evidence. For example, the fact that people have near death experiences, as well as the general features of the NDE are based completely on anecdotal evidence. They are nevertheless accepted as scientific fact.
