I agree with you. But, I wonder if we (as a group) are using the same definition of "stuttering" -- as in are we discussing the behavior (actual disfluencies) or the condition (being one prone to disfluencies). You (I think) and I are using the definition that refers to the condition of stuttering. thus, as a group, people who stutter do not have lower self-esteem (however that is defined) relative to people who do not stutter. However, I bet others are using the behavior definition. The frequency and severity of stuttering moments can be increased by various components that can be interpreted (albeit sometimes falsely) as low self-esteem (e.g., lack of confidence in the material, high stress situations).
