That’s right. The lexical hypothesis only comes in at step 1 by including questions like “I am [adjective].” We start with a vague theory in the questionnaire and apply dimension reduction. The lexical hypothesis is that language gives us a vague theory. We want as broad a theory as possible, so it is useful to combine questionnaires. Some sources claim that the original questionnaire was generated from language without questions from explicit theories, but I don’t think that’s correct.
