The fact of the matter is, the article here is a brief overview describing none of the actual scientific literature at a level that should be convincing to a medical practitioner. But you read it and are apparently convinced of the author's point. So, a layperson (I assume, in your case) is presented with some well-written evidence from an authoritative perspective, alongside broad contours of the actual medical evidence but no details, and is convinced that it's true. Is it so hard to believe that a child welfare worker would be equally convinced under the same circumstances when talking to a doctor, neurologist, trauma surgeon, etc. who believes the opposite as this author?
