The positive effects that have been noted when using hypnosis have been explained in a number of ways. one suggestion is that the relaxed state that accompanies a "hypnotic trance" is uniquely responsible for all of the effects. this reminds us of which principle of critical thinking from your book?

Ruling out rival hypotheses, Findings consistent with several hypotheses require additional research to eliminate these hypotheses. More five principles of critical thinking are: (1.) Correlation vs. Causation, the fact that two things are associated with each other doesn’t mean that one causes the other. (2.) Replicability, a finding must be capable of being duplicated by independent researchers following the same recipe. (3.) Occam’s Razor, if two hypotheses explain a phenomenon equally well, we should generally select the simpler one. (4.) Falsifiability, claims must be capable of being disproved. (5.) Extraordinary Claims, the more a claim contradicts what we already know, the more persuasive the evidence must be before we should accept it.
