To explain the title of the post: "*What causes mild error prone speech to get mislabelled as an actual stutter disorder*". This title implies that, in my opinion, we should accept incipient stuttering (mild error prone speech). Because if we do not accept our mild error prone speech (or we are simply not aware of it), then it could increase our perfectionistic expectations (aka cognitive distortions) regarding how perfect we should sound (which could raise the execution threshold too high to say our thoughts out loud, and then we learn to stutter through operant conditioning). The same principle applies if we label incipient stuttering as an actual stutter disorder (which creates cognitive distortions that could poorly fine-tune the release threshold, and then we learn to stutter)
