the phrase "peer-reviewed", on its own, should have about as much evidentiary weight as the phrase "doctor-recommended" in a late-night commercial.
@interfluidity
Its value has to depend on context. "My doctor said" in a conversation means something different than "doctor-recommended" in a late night commercial.
@necoleman Absolutely. "My doctor said" is very different than a public pitch's "doctor recommended".
Similarly, that a researcher I really respect has endorsed a study as worth taking seriously contains a lot more information than "peer reviewed".
