> Withholding school from children (in a developing country) in a long term experiment is completely unethical.
Yes, I agree, and that is why the required science cannot be done -- the science you think exists in psychology.
> I think you should really research ADHD more thoroughly.
I have researched it, I know this topic much better than you do, and at present ADHD is firmly in the pseudoscience category. This is not to say it's not real, it is to say that no one has any idea what it is, and we cannot objectively diagnose it. This means it's open to various kinds of abuse, in particular if its diagnosis relies on self-reporting and questionnaires, the bane of modern psychology.
> It doesn't get any better.
Science is better. But to understand that, you would have to understand science.
> ADHD diagnosis in terms of questionnaires PREDICTS anatomical, physiological and psychological differences.
Questionnaires? Self-reporting? This is worse than I thought. You show me a microphotograph of a pathogen (or a distinctly abnormal group of brain cells, or a cluster of genetic defects, or anything objective at all) that causes ADHD, and I will grant that the required science has begun. Until then, an ADHD diagnosis depends on how a questionnaire is filled out, which means people can get the diagnosis if they want it and if they know what to say in the questionnaire (or the reverse, if that's their preference).
> Insisting on ADHD not being a diagnoseable, treatable syndrom is almost as dangerous as saying "vaccines cause autism".
You're obviously unaware that Thomas Insel, chairman of the NIMH, holds the same views on this topic that I do:

Quote: "While DSM has been described as a “Bible” for the field, it is, at best, a dictionary, creating a set of labels and defining each. The strength of each of the editions of DSM has been “reliability” – each edition has ensured that clinicians use the same terms in the same ways. The weakness is its lack of validity."
"Unlike our definitions of ischemic heart disease, lymphoma, or AIDS, the DSM diagnoses are based on a consensus about clusters of clinical symptoms, not any objective laboratory measure. In the rest of medicine, this would be equivalent to creating diagnostic systems based on the nature of chest pain or the quality of fever ... Patients with mental disorders deserve better."
Ten years ago I was having the same kinds of conversations about Asperger Syndrome. Now Asperger Syndrome is gone, discredited. Does this mean that ADHD is another phony condition? Not likely, but no one knows, because no one is doing the required science.
I'll say it again for the record -- ADHD will become a real condition when we know what causes it, and not before.
Science requires testable, falsifiable explanations. Psychology is stuck at the description stage, and has been for decades.
