The Rational Offender The “Classical School” Deterrence Theory Rational Choice Theory Routine Activities Theory

Social Context of the “Classical” School Prior to the 1700s “The devil made me do it” Punishments/justice system?

Social Context II Classical School Criminology (1700s-1800s) Bentham, Beccaria, others rail against an “inhumane” justice system Along the way, they articule a “general theory” of human behavior Borrow heavily from Thomas Hobbes

Becarria An Essay on Crimes and Punishment (1764) On the origin of punishment (Hobbes) What is the nature of human beings? “War of all against all” What should be done to the system of laws? Interpretation of Laws Obscurity of Laws

Beccaria II What is the purpose of punishment? “Prevent the criminal from doing further injury to society, and to prevent others from committing the like offense.” Necessary conditions for this? Proportion between crimes and punishment Advantage of immediate punishment Certainty more important than severity

The Classical School Fades By the early 1900s, most dismissed this as a valid theory of criminal behavior What emerged is called the “Positive school” Changes in legal system didn’t lower crime rates “Armchair theorizing” questioned Humans as “determined” rather than “rational” From early 1900s until the 1970s, the positive school was unchallenged Sociology was dominant force (search for root cause)

Rebirth of Deterrence Social Context of U.S. in the 1970s James Q Wilson, Thinking About Crime There are no “root causes of crime” Martinson “Nothing Works” in rehabilitation Murray “Punishment Programs” rather than rehab programs Economists enter Criminology Becker’s “Rational Choice” article

Current Neo-classical Theories Deterrence theory Swift, certain, severe punishment reduces crime Focus on formal punishment Rational Choice theory Focus on how rational offender is The “flip-side” of deterrence Routine activity theory

Deterrence Theory Assumptions 1. Humans are Rational (cost/benefit) 2. Humans are self-interested and hedonistic 3. Human behavior can be controlled through certain, swift, severe punishment

Deterrence Theory Criminal behavior (or crime rates) vary directly with _______ of FORMAL punishment. Certainty Severity Swiftness MICRO or MACRO? Specific or General

Marginal versus Absolute Absolute deterrence: the existence of formal punishment reduces crime Marginal: increases in existing formal punishment reduces crime further

General Deterrence (Macro) What should reduce crime rates? Evidence: Severity of Punishment Death Penalty Research Certainty of Punishment Experiments in Certainty (KC patrol) Swiftness of Punishment?

General Deterrence Micro Level An individuals perceptions of _______ influence their decision to commit crimes. “Perceptual Deterrence” Criticism of “objective” = do people really know the clearance rate? Better: what do you think the clearance rate is?

Perceptual Deterrence Research Initial cross sectional studies: Perceived risk, severity SR crime But, what is the causal order?? “Experiential” effect SR crime perceptions or certainty/risk Manipulation of Perceived Risk Scared Straight

Specific Deterrence A person who commits a crime and is punished is less likely to commit additional crimes. Swift, Certain, Severe (Marginal) How test these propositions?

Testing Specific Deterrence Prison vs. Probation? Perhaps, “time in prison” or “type of prison” More realistically Probation vs. Intensive Probation Probation vs. Boot Camp

Deterrence Review: Deals only with formal legal sanctions. Is this fair? Classical school roots, policy implications Empirical Support? General Deterrence Macro Micro (Perceptual) Specific Deterrence

Why little support for deterrence? We can’t get certain, severe, swift enough The theory is based on bad assumptions How rational are we? Equality of opportunity, pleasure, pain? “Marginal” deterrence

POLICY IMPLICATIONS General Deterrence: certain, swift, and severe punishment reduces crime rates, or the probability that an individual will offend Specific Deterrence: CS&S punishment reduces recidivism Can’t/Won’t make sentences swift, certain, and severe enough? Incapacitate
