I appreciate what you are saying, but cannot agree that there would be no profit motive to mimic an "exact science" because of the Prisons for Profit problem in this country.I understand that you feel it is important, I really do. And I understand that you learned the concept of "proclivity offenders registry/list" in an undergrad Jurisprudence class. Undergrad classes always make for developing good critical thinking and yet at the same time, tend to make one think that whatever topic/subject at hand is of urgent importance.
Here's what I'm saying:
If you had taken an Actuarial class, what would be focused would be statistics say of those who will inherit heart disease (if we want to stay on genetics & inheritability). See, there's money in that arena and therefore a slight chance that it stands to be enacted possibly further down the road.
Money changes things and moves research forward but there really is very little money for any agency or private sector to push for "proclivity registries" for mental health. We all know that psycho/social dynamics impact development and the outcomes of personality disorders and emotionality. There is no guarantee, "recipe" or perfect science to pre-determine who will become a murderer. Heck, we can't even get basic mental health care in this country, let alone a leap out to the abyss of a "proclivity registry".
So that's why I have said I wouldn't worry about it so much, SMK. Science will progress regardless of our concerns and worries about eugenics will always be there. I understand completely.
It would be very, very profitable for some institutions to contain people, to lock them up, for the reason that they may have a proclivity to offend. In fact, this has already been done with many juveniles and with youth with certain mental disabilities (with many backlash groups forming and complaining, thanks be to God).
So I think statistically it remains a formidable worry. (Just as when they speak of certain new early and precise in vitro testing methods to screen out many genetic disorders : One immediately thinks of the possibility of a world where bipolars, Downs syndrome, etc. have been banned. ) Yes, eugenics abuse has and will remain a concern, as you say - and with good cause.
