I agree with you. I also think that the psychosocial aspect of stuttering is important. I too was the class president as a stutterer.. I agree that courage and our own beliefs are important as well.. they can make us more resilient against relapse. I think that for some stutterers mindfulness helped them to achieve stuttering remission (see for example, page 356 in The perfect stutter), while for other stutterers - small subtle changes in mindset/attitude led them to achieve stuttering remission (see for example, the research: "Spontaneous" late recovery from stuttering, 2019). Yet for others, a stutter technique led them to enough confidence in their ability to control their speech - long enough that it eventually led to stuttering remission i.e., a phase where they no longer need to use a technique to speak fluently. So, I believe that addressing one's mindset/attitude can in some cases resolve the internal conflict (or anticipated errors) and bypass certain triggers of stuttering, and thus break the vicious circle of "stuttering persistence", I argue
