The future that psychologist Dr Adrian Raine predicts—from a civil liberties perspective, at least—falls somewhere between Philip K. Dick's most outlandish speculations and a genuinely serious cause for alarm. Here are the basics: come 2034, with the economic cost of crime spiraling and the public sick of murder headlines, the US government introduces a program of mandatory brain scanning for 18-year-old men and women.
The scan cross-references every young person against a database of criminal genetics. It looks out for matches in three areas: violent assault, sexual assault, and murder. A score above 79 percent in the first category, 82 percent in the second, and 51 percent in the third will, in Raine’s dystopia, see the so-far-innocent 18-year-olds locked up in luxurious preventative "prisons." Indefinitely. Until some kind of therapy reduces their score or they’ve been subjected to a Ludovico technique so many times that they flick their own kill switch.
