hmm I could try that Auntie, well there are general scales they measure these sorts of things on I think or how could they know if someone was callous or just not showing what they felt? Unless physcologists haven't figured out yet that not showing feeling's isn't the same as not having them... -> Interesting side note they have disproved physcopaths having no empathy, thier empathy switch is just off in thier "default" state but it can be switched on.
