Paul, I beg and plead. We need a discussion about how we determine things.
There are more scientific papers released each day than any one person can simply read, let alone understand, or follow the included citations. It would take you and I years of study just to become conversant with the background of research into autism. You want me to read that paper, out of the thousands of relevant papers, but on the other hand you have consistently neglected counter-evidence presented on this thread, and forged on ahead thereby omitting discussion of it.
This is advocacy, not investigation.
Please tell me, how did you come by that particular paper?
