Are you referring to the conversation when said "correlation doesn't equal causation"? And when you tried to falsely make up a definition of developmental stuttering by the DSM-IV and then when I called you out on it being false, you stated, "Huh? That wasn’t a definition, and I’m typing on my phone, so I used the old terminology accidentally." Or when you shared a paragraph on CBT as being helpful for stuttering but the paragraph itself stated, ""*CBT had no impact on stuttering frequency*". That conversation is unrelated to this conversation so let's focus here. Anyway, your argument here is that "anxiety goes in both directions, as both a cause and an effect". Yet you are unable to provide me any evidence to confirm this. Stuttering and anxiety have an association, this is true, but there is no evidence that anxiety causes stuttering. Stuttering can occur when you are feeling anxious, but it can also occur when you're not feeling anxious. It can also be a by-product of a stuttering moment. Anxiety is low hanging fruit. In fact, stating that anxiety causes stuttering puts the blame on the person who stutters, "if only I was not anxious, I wouldn't stutter" No. People who stutter are not to blame for their stutter because there are many neurological things occurring in the brain, other than anxiety.
