The indirect measurement method required a long questionnaire to yield statistical soundness

Evidence

Adorno tried to calm his fears about the large number of questions. Only some of the questions would be included in the final questionnaire. Which of the questions were generally applicable, and which would only be used selectively for specific groups, still had to be tested. Otherwise, in the indirect analysis itself, which had appeared as an entirely new idea, it would not be possible to make do with a very short questionnaire, as in the Labour Study'. There would not be sufficient material to provide the statistically sound conclusions’ which were the point of the exercise for them. — Rolf Wiggershaus, The Frankfurt School, 1579
