Hypotheses are all people seem to be interested in anymore. Maybe the public should me more aware of exactly what a hypothesis is. A hypothesis is a statement that describes the aim of an experiment. It is basically an assumption which must be proved or disproved by an experiment. In this case the only type of experiment which could achieve this is to take a sample of genetically identical children (for example several sets of twins), administer the drugs to one half and not the other and monitor them for a few years.
I don't need to remind anyone that such an experiment would be ethically unacceptable - but it does highlight one obstable that the researchers face.
The problem is that as soon as one of these hypotheses is announced, the media pounce on it and the gullable public just lap it up.
Look on the bright side. If you're ever short of money, all you need to do is grab a lawyer, tell them about how autism has ruined your life and sue some random drugs company :twisted:
