Of course stuttering is the miscoordination between the brain and the muscles that produce speech. You have to learn to not read literally. I was not disregarding that reality. I am, however, correct in claiming that stuttering is also by dint of hyper consciousness and anxiety. If you want to just do a google search you can but, frankly, I don’t care enough to cite my sources in a reddit comment. I understand that it is “not your (individual) experience” but using anecdotal evidence in support of your claims is not valid. After re-reading your comment I just saw that you claimed “there’s no hyper consciousness or anxiety...” to claim that these play no role in stuttering is ludicrous ...
