Evidence limit
How repetition becomes certainty
Care sheets often copy other care sheets. Qualifying words disappear, an observation becomes a rule, and eventually the number of repetitions is mistaken for proof.
Common examples include exact wild diet percentages, universal bans on juvenile brumation and claims that one substrate alone explains every impaction.
Research
A better test
Ask what was studied, which species was involved, how many animals were examined and what the researchers actually concluded. Then check whether the claim goes further than the source.
When no direct evidence exists, that does not make experience worthless. It means the statement should be presented honestly as a practical observation, breeder experience, veterinary judgement or precautionary policy.
