How about the practical part of behaviorism, operant conditoning?
It looks much more like engineering than like science to me. I don't know it enough to have an opinion on how well it works.
Surely you realize that stability across individuals if not really to be expected overall in detail.
Of course and that's one of the reasons for me having doubts about the "sound science" label.
you just need to explain variation
Post factum..? :-)
In any case, if it all worked as well as you claim, surely psychotherapy for kids would be very effective. I suspect this is not the case in reality.
Actually if it works as well as I claim, psychotherapy for kids might be less effective. It involves changing the kid's environment. Psychotherapy can't do that. You have to get the parents to be willing to change and give them training.
On the contrary, the fact that psychotherapy works at all is evidence that the operant conditioning methods I am pushing are not the whole story, and of course operant conditioning is not the whole story.
By your definition, medicine is not a sound science because stability overall in detail is not to be expected due to genetic variability.
Sir, Could I See Your Breeding License?
Most important is that children don't have to grow up under horrible circumstances inflicted on them by the inability of their parents. You always have to weigh the freedom of some against any negative infliction it could have on others. In this case a bit less freedom would guarantee a lot less distress.
It is reasonable. I don't see how we can ask for species-appropriate animal husbandry regarding animals like chimps but not children. You have to have a drivers license for good reasons too. So why is everyone allowed to rule over helpless human beings for years without having to prove their ability to do so in a way that guarantees the well-being of their protégé?
Such discussions always remind me about something important. Children should not be assigned with any religion. There should be a certain age where they can decide what religion they want to follow, if any. This doesn't mean that religious people shouldn't be able to have children but that they shouldn't be able to force their children into a certain framework either. Parents should be forced to allow their children to take part in a educational framework based on contemporary ethics and knowledge. I don't even have a problem with lessons in religion in school as it is part of human nature. But it shall not be focused on any truth value or a certain religion but an overview and comparison with non-religious ethics and truth-seeking.
