The question

QUESTION-030 asks which interventions tell constitutive relations from diagnostic ones. Most designs that propose to answer it, vignette and rating studies among them, change what the interpreter is told: that the speaker is a friend, has authority, or made a commitment earlier. This question asks whether an intervention of that kind can bear on constitution at all.

The answer

CLAIM-130, Active, answers it: no, not by itself. In the structural model A129 §1 writes, do(I = a) and do(S = s) act on different variables, and nothing in the model makes their effects on the judgement equal (THEORY-419, THEORY-138). A191 §6: “If we merely tell participants that an utterance is a reprimand, and they subsequently classify it as a reprimand, we have learned something about interpretation under instruction. We have not necessarily demonstrated that the underlying speech act changed.” A do(S) needs a design in which the speaker’s role or the conversation’s history actually changes.

What stays open is QUESTION-030’s: which do(S) designs tell constitutive relations apart, and the conceptual half, which needs a theory of the act.
