Kiehl and the staff at Mendota are now asking some 300 young men to slide into a mobile brain scanner. The scanner records the shape and size of key areas of the boys’ brains, as well as how their brains react to tests of decision-making ability, impulsivity, and other qualities that go to the core of psychopathy. Each boy’s brain will be scanned before, during, and at the end of their time in the program, offering researchers insights into whether his improved behavior reflects better functioning inside his brain.
Also, "while adult psychopaths constitute only a tiny fraction of the general population, studies suggest that they commit half of all violent crimes.". This is beyond scary. I wonder how we, as a civilization, can get psychopathy under control? We have 1 percent of the population that places enormous burden on the society, and we still act as if they are normal people. Why there's no requirement for psychopathy assessment for jobs like police officers or civil servants? Should we apply mandatory psychopathy testing to all convicted criminals and divert the positives into a specially-designed life track - and what would that life track even look like?
