Story

It occurs to me this would be a pretty good plot/subject for a science fiction movie - some kind of obligatorily-worn mood changer. The risk of abuse is obvious too: imagine a totalitarian society that has dealt with the problem of pedophilia/etc by making anyone convicted of it wear the helmet that dulls that urge by electrically stimulating some nerve center in the brain. What would those helmet wearers do? What would that say about society? Repeat for other crimes - thought crime, etc.

That's a great story; I think I'll write it.
