Extraordinary Claims – The more a claim contradicts what we already know, the more persuasive the evidence must be before we should accept it.
Falsifiability – Claims must be capable of being disproved.
Occam’s Razor – If two hypothese explain a phenomenon equally well, we should generally select the simpler one.
Replicability – A finding must be capable of being duplicated by independent researchers following the same “recipe.”
Ruling Out Rival Hypotheses – Findings consistent with several hypotheses require additional research to eliminate these hypotheses.
Correlation vs. Causation – The fact that two things are associated with each other doesn’t mean that one causes the other.
