Surely you've already made up your minds about IQ and here's a video anyway. IQ is the best measurement in social sciences. IQ is the greatest predictor of success. The military says that people with an IQ under 83 are ineligible (i.e. useless). 10% of people are under 83. Unruly behavior at age four correlates highly with criminal behavior at 15-20. Interviewer gives a speech as a question. This all got me thinking about both the morality and public necessity of taking care of people who sincerely can't contribute in a capitalist society. It also got me thinking that effective state intervention is going to require getting involved far earlier than the age when antisocial behavior turns to criminal activity. This topic can go any number of ways, including the morality of a punitive legal system, so feel free to spitball thoughts. *no fact-checking took place prior to the posting of this thread.
