Streetlight Effect: People tend to get their information from where it’s easiest to look. E.g. the majority of research uses only the sources that appear on the first page of Google search results, regardless of how factual they are. Cumulatively, this can skew an entire field.

Woozle Effect: An article makes a claim without evidence, is then cited by another, which is cited by another, and so on, until the range of citations creates the impression that the claim has evidence, when really all articles are citing the same uncorroborated source.
