This is why real validity is hypothetical.However, people can have a judgment about the validity of measurement-instruments. This validity-judgment doesn’t have anything to do with the real validity.In psychology, true causal strings are (yet) impossibleThat is why psychology temporarily deals with hypothetical validity-judgments.
