SINCE RESEARCH BY SOCIAL SCIENTISTS HAS TENDED TO DISCREDIT CONVENTIONAL METHODS OF IMPRISONMENT AND THERAPEUTIC REFORMATION, SOCIAL PHILOSPHERS SHOULD EXAMINE THE MEANS OF DEALING WITH CRIMINALS. THE FOLLOWING CRITERIA CAN BE USED TO COMPARE VARIOUS METHODS OF HANDLNG PRISONERS: (1) IS ONE METHOD MORE OR LESS EFFECTIVE THAN ANOTHER ALTERNATIVE (2) IS ONE METHOD MORE OR LESS LIMITED IN SCOPE THAN ANOTHER ALTERNATIVE AS FAR AS ITS INFLUENCE ON A CRIMINAL'S WHOLE SET OF SOCIAL VALUES; AND (3) IS ONE METHOD MORE FAIR THAN THE ALTERNATIVE; ACCORDING TO THESE CRITERIA, THE AUTHOR EXAMINES THREE ALTERNATIVE TREATMENT METHODS. IN AVERSION THERAPY, CRIMINALS ARE REPEATEDLY EXPOSED TO SOME COMPONENT OF THEIR CRIMINAL ACT (SUCH AS A GUN) AND AT THE SAME TIME SUBJECTED TO SOME AVERSIVE STIMULUS (SUCH AS INDUCED NAUSEA). AVERSION THERAPY HAS SPECIFIC, LIMITED EFFECTS ON A CRIMINAL'S PERSONALITY, BUT IT CAN BE EFFECTIVE AND IS CONSIDERED TO BE INHERENTLY LESS UNFAIR THAN IMPRISONMENT. MONITORED PROBATION, A METHOD OF DIRECTLY CONTROLLING OR SCRUTINIZING BEHAVIOR OF CRIMINALS, MAY DETER AT LEAST AS WELL AS PRISON SENTENCES ACCORDING TO RESEARCH. BY ATTACHING ANTHROPOTELEMETRIC DEVICES TO PROBATIONER'S BODIES, AUTHORITIES COULD MONITOR THEIR LOCATIONS, CONVERSATIONS, AND POSSIBLE USE OF WEAPONS AND TRY TO DISCOURAGE THEM FROM GETTING INTO CRIME-RISK SITUATIONS. MONITORING, DUE TO ITS LIMITED INFLUENCE ON VALUES AND ITS DISTASTEFUL INTERFERENCE WITH CRIMINALS' PERSONAL FREEDOM, WOULD BE PREFERABLE ONLY FOR SERIOUS CRIMINALS FACING VERY LONG OR INDEFINITE INCARCERATION. A SYSTEM OF PAYMENT OR REPARATION TO THE VICTIM AND TO SOCIETY MAY BE A BETTER DETERRENT THAN IMPRISONMENT OR THERAPY. THE STATE PROBABLY WILL HAVE TO PROVIDE CRIMINALS WITH EMPLOYMENT OPPORTUNITIES THAT WOULD ALLOW THEM SUFFICIENT FUNDS TO PAY THE FINES. REPARATION MAY BE MORE UNFAIR THAN THE OTHER TWO ALTERNATIVES, BUT CAN HAVE A GREATER EFFECT ON THE CRIMINAL'S BEHAVIOR. REFERENCES ARE PROVIDED. (DAG)
