      This is a variant of the "one true study" fallacy. For examples, antivaxers will sometimes challenge me to show them the "one study" that shows that vaccines are safe and effective. 1/https://twitter.com/GidMK/status/1118128113022578689 …

      One thing I think a lot of people get confused by is what scientists mean when they say "new evidence could absolutely change my position" Often, people think this means one study, and get upset when they're told one study changes nothing

      They react poorly when I patiently try to explain tha our conclusion that vaccines are safe and effective comes not from any one study, but from a confluence of hundreds, if not thousands, of studies all converging on the same conclusion. 2/

          This fallacy, I think, comes from the often legalistic thinking, rather than scientific thinking, that cranks often engage in. For instance, in law, there is a principle known as falsus in uno, falsus in omnibus, which means "false in one thing, false in everything." 3/

          In common law, it is the legal principle that a witness who testifies falsely about one matter is not credible to testify about any matter. 4/

          Antivaxers often misapply falsus in uno, falsus in omnibus to scientific studies, with a twist. To them, if one study doesn't support the scientific consensus that vaccines are safe and effective, it overthrows the scientific consensus that they are. 5/

          Of course, one study rarely is enough to overthrow a scientific consensus, and the stronger the scientific consensus the more is needed to throw it into doubt. Not all studies are created equal, and studies cited by cranks are often among the crappiest. 6/

          Understanding science means understanding how to weigh large quantities of scientific evidence, something antivaxers and other cranks often fail spectacularly at. 7/7
