Reducing stuttering to conditioning and confidence is reductionist and not grounded in any research. I have reviewed your theories in the past and shown you're just making theories up yet you just double down on them again and again. I don't understand what your aim is. You say that you're trying to understand how stuttering works but how can that be your main motivation when there is a mountain of research done on how stuttering works that you ignore. Your sources lead back to this one guy, are you promoting his work for financial gain? How can we make real progress when people just make stuff up and call it a theory? I am harsh on you because I doubt your intentions.... It is clear that you are scientifically literate but you choose to be dishonest.
