But people should be aware when doing studies, that if you assume a DSM diagnosis as the definition of Autism, and then go on to study and make conclusions about "autism" then you are indeed using a circular proof.

Edited to add - it is circular if people then take their own definition, do studies on what they have defined and then conclude things about the subjects/condition based on that study.The word "autism" means whatever the definitive source says it means - that isn't circular
mvic wrote:An example is early studies on Aspergers excluded women because they "muddied the data". These studies were used to refine what Aspergers meant and create new proofs and definitions - if they were really nonsensical it could have been taken as far as to prove "women don't get aspergers". Because it was defined by the male form of the condition. You see how this is meaningless.
