Himalayan salt does not have lower levels of sodium than conventional table salt. [184] Glass does not flow at room temperature as a high-viscosity liquid. [185] Although glass shares some molecular properties with liquids, it is a solid at room temperature and only begins to flow at hundreds of degrees above room temperature.
Social-science methodologist Donald T. Campbell, who emphasized hypothesis testing throughout his career, later increasingly emphasized that the essence of science is "not experimentation per se" but instead the iterative competition of "plausible rival hypotheses", a process that at any given phase may start from evidence or may start from ...
Caution readers that studies that do not have scientific consensus might not be reliable. For example, link to levels of evidence, explain the strengths and weaknesses of a certain type of evidence, or quantify how likely something is to pan out (e.g. how many drug candidates become approved drugs, or how many psychology studies fail attempted ...

"Extraordinary claims require extraordinary evidence" (sometimes shortened to ECREE), [1] also known as the Sagan standard, is an aphorism popularized by science communicator Carl Sagan. He used the phrase in his 1979 book Broca's Brain and the 1980 television program Cosmos .
