Which of the following is not related to the 'distillation of the maximal image' of Post-Behaviourism ?

The statement "It is better to be wrong than vague" is not related to post-behaviouralism; it was the earlier behaviouralist maxim. In outlining the "Credo of Relevance" (the distillation of the maximal image of post-behaviouralism) in 1969, David Easton contrasted that earlier maxim with the post-behaviouralist dictum that "it is better to be vague than non-relevantly precise," alongside placing substance before technique and emphasizing the social responsibility of intellectuals.
