Of Conspiracy Theories
Abstract
As the end of the Millennium approaches, conspiracy theories are increasing in number and popularity. In this short essay, I offer an analysis of conspiracy theories inspired by Hume's discussion of miracles. My first conclusion is that whereas Hume can argue that miracles are, by definition, explanations we are not warranted in believing, there is nothing analytic that will allow us to distinguish good from bad conspiracy theories. There is no a priori method for distinguishing warranted conspiracy theories (say, those explaining Watergate) from those which are unwarranted (say, theories about extraterrestrials abducting humans). Nonetheless, there is a cluster of characteristics often shared by unwarranted conspiracy theories. An analysis of the alleged explanatory virtues of unwarranted conspiracies suggests some reasons for their current popularity, while at the same time providing grounds for their rejection. Finally, I discuss how conspiracy theories embody an anachronistic world-view that places the contemporary zeitgeist in a clearer light.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
