This has nothing to do with stuttering. Plenty of people have extreme social anxiety and they don't stutter. People that stutter have different brain activity than non stutterers, this has been proven multiple times by science. The reason why most don't stutter alone is because the brain uses different parts of it when you speak to another person. The process of speech gets more complex and stuttering is trigged. Yes social anxiety makes it even worse but it is not a trigger. Please stop sharing misinformation, u are hurting the community
