The idea
Clinicians and researchers often treat the intervention strength-of-evidence pyramid as universal for all types of clinical question.

A meaning question ranked against a hierarchy built for interventions.
Where people slip
In that pyramid qualitative studies sit near the base and the randomized trial near the apex — which is correct for interventions and meaningless for meaning.
