>if your stutter is noticeable in any way, they will know Yup. And people in general are very uninformed about stuttering, so when they notice you stuttering, a lot of them would assume that it’s at least partly due to extreme nervousness and anxiety, and that the secondary movements you do are a sign of lacking social skills/self awareness/manners, or a bad habit, or even a sign of a mental illness (a surprising number of people I encountered believe this). For me disclosing and explaining briefly about the secondary movements gives me a bit of control over how people view my speaking ability, and it’s better than not having that control at all. My work requires me to talk with people a lot (sometimes taking back-to-back video calls for hours) so I always disclose during the interviewing and training stage, letting them know that my ability to speak coherently and at an appropriate speed for extended periods is not affected by my stutter, and that my head and face movements are a physical symptom of my stutter.
