for me I have 135+ IQ and I was the number one student throughout my school career، Compared to my colleagues, I am good at learning new things very quickly and I have some creative intelligence، I still don't know if there is actually a link between stuttering and intelligence، According to what I have read, there is no clear scientific evidence on this topic,The strange thing is that I dont stutter when I speak in English or Japanese, but when I speak in my mother tongue (Arabic) I stuttering horribly, I think my stuttering is genetic because my father also stutters That's why I have no hope of treating it.
