One must naturally wonder what makes such practice in the field possible. The answer, I believe, lies in the fact that we have failed to develop a rigorous means to evaluate hypotheses in generative grammar. What is needed most critically is, in my view, a good understanding and articulation of the logic of hypothesis-testing in generative grammar, and the development of a minimally satisfactory structure of our experimental design and its justification.

Over 5 years have passed since the posting in [29943]. The current methodological articulation, as briefly summarized under the thread in Methodology [42404] "The current articulation of the methodology of language faculty science as an exact science" seems to me more satisfactory. Many of the specific points made there are illustrated in my book draft by results of on-line experiments along with how various aspects of experiments get improved, in line with the the proposed methodology.
