There is a lot to unpack that is difficult in a reddit reply thread with multiple conversations happening at once, so I am more than happy to continue discussing it with you if you'd like. Here are some broad thoughts that I have and will leave with all of this. Yes, we don't have the answers to everything and realistically we won't for a while. That is why research exists and there are people with all kinds of beliefs and backgrounds trying to answer questions. You are free to believe whatever you may like and that is fine. I would heavily caution against promoting any theory as fact or public information when there is little to no evidence supporting it regardless of what the topic or theory is. I very well may be wrong, and science may come to show that later on, but for now we don't know enough to push that it is true. Since you have brought up psychogenic stuttering a couple times, I will offer this thought. Psychogenic stuttering is usually caused by trauma and may be a more appropriate disorder for this theory rather than developmental stuttering. However, they are not comparable to each other similarly to how neurogenic stuttering is different being caused by a brain injury. They display similar symptoms but are not the same. Just like people with different subtypes of dementia (Alzheimer's, vascular, frontotemporal, etc.) all have some similar characteristics, including memory loss, but are not the same disorder even if having similar therapy methods. Finally, in no way did I claim that they were fools or unintelligent. Having a theory disproved or unsupported doesn't imply someone isn't talented or smart, it just means that the theory was disproven and not in line with data. You can be a great researcher and still be wrong sometimes. That is true for everyone, which is why we continue studying and learning and investigating. People at one time thought the earth was flat, and the sun rotated around the earth. Those people aren't automatically stupid, they just didn't have the information and technology we do now. In 50 years, we could have information that completely supports this theory, and we may have information that completely expels it. For right now, we are limited in what we know which is why we need to be careful in what we spread to the world because we truly don't know. Publicly sharing unsupported information can cause more harm than good, even if it's just a theory. In many circumstances, there is an ethical responsibility to share information based on facts and data, not just on feelings and thoughts. I wish you the best with your study!
