Another critical target is behavioural psychology (popular ca. 1940-60s), as propounded by the psychologists John B. Watson and B. F. Skinner. Novelist Burgess disapproved of behaviourism, calling Skinner's most popular book, Beyond Freedom and Dignity (1971), "one of the most dangerous books ever written".[7] The film's Ludovico technique is widely perceived as a parody of behaviorist-based aversion therapy.[8] Although Watson conceded behaviourism's limitations, Skinner argued that behaviour modification (systematic reward-and-punishment learned behaviour techniques, which differs from Watsonian conditioning) is the key to an ideal society (see the 1948 utopian novel Walden Two). Dr. Ludovico's behaviourist technique of conditioning Alex to associate violence with severe physical sickness, to curb his violent nature is akin to the CIA's Project MKULTRA of the 1950s. Dr. Ludovico's behaviourist technique is based on classical conditioning, which is not quite the same as with B. F. Skinner's operant conditioning.

Think of the code from your iris as a built-in social security number, but better.  Every time your iris is scanned, the scanner should spit out the same number.  So the cops will have no question that your iris is the same one that they scanned 6 months before or 10 years before when they pulled you over.  They (and anyone else) can tie whatever information they like to your iris scan id.  There is no need to match your drivers license number to the one you had ten years ago or to your credit history in another state.  No confusion on no-fly lists with multiple people having the same name (and probably no easier time getting off the no-fly list once you get on).  And no getting a new id number when you are a victim of identity theft.
