A corollary of the false positive paradox is that sensitivity in measurement of stuttering can be relatively low (90% is suggested) before general population estimates of stuttering prevalence are appreciably affected. Despite this relaxation of measurement requirements regarding sensitivity, covert stuttering is likely to have been underestimated.

Our stuttering is as much a part of us as any other attribute. For others to know us deeply, they must also know our stuttering. Likewise, for us to know others, we must know how they react to us – all of us – including our stuttering. In this paper, I propose that by stuttering openly and sincerely we share more of ourselves with others and, therefore, enter a deeper communion than would be possible if we hid our disfluencies. Stuttering introduces vulnerability into our conversations that would be absent had we been fluent. This vulnerability, when reciprocated, allows for intimacy.
