Criminology: Rational Choice Theory and Deterrence

Offenders make decisions influenced by perceived opportunities, benefits, risks, and costs, although their information and reasoning may be limited.

Derek Cornish and Ronald Clarke.

Decision-making constrained by incomplete information, limited time, cognitive capacity, emotions, and situational pressures.

Crime-specific decisions concern whether and how to commit a particular offense; offender-specific decisions concern broader involvement in criminal activity.

The perceived overall value of an action based on anticipated benefits, costs, and their probabilities.

Discouraging members of the public from offending through awareness of legal consequences imposed on others.

Discouraging an individual from reoffending through consequences personally experienced.

Certainty, severity, and celerity or swiftness of punishment.

The promptness or swiftness with which punishment follows an offense.

The perceived certainty of detection and punishment, rather than extreme severity.

The influence of an individual's subjective beliefs about the likelihood and consequences of punishment.

The principle that differences in punishment severity may encourage offenders to choose less harmful conduct over more harmful alternatives.

Absolute deterrence concerns preventing offending altogether; marginal deterrence concerns discouraging more serious offenses or harmful conduct.

Offenders may favor targets they perceive as accessible, rewarding, and relatively low risk.

A theory explaining crime events through the convergence of a motivated offender, a suitable target, and the absence of capable guardianship.

Lawrence Cohen and Marcus Felson.

A motivated offender, a suitable target, and the absence of a capable guardian.

A person or measure whose presence or intervention can discourage or prevent an offense.

The extent to which an object or person appears attractive, accessible, or vulnerable to potential offenders.

Value, Inertia, Visibility, and Access, four characteristics used to assess target suitability.

The physical resistance of a target to being moved or stolen, such as its size or weight.

Routine activity theory emphasizes opportunities and the circumstances of crime events rather than primarily explaining an offender's underlying motivation.

The study of how crime patterns are influenced by the spatial, temporal, and environmental contexts of everyday activities.

Patricia Brantingham and Paul Brantingham.

A perspective explaining crime locations through offenders' routine movements, awareness spaces, and encounters with opportunities.

A place frequently visited during ordinary routines, such as a home, school, workplace, or shopping area.

A route connecting activity nodes along which people regularly travel.

A boundary between areas with different land uses, activities, or characteristics that may influence crime opportunities.

The geographic area an individual knows through routine travel and activities.

A location attracting many people for legitimate reasons, where crime opportunities arise from the concentration of potential offenders and targets.

A location known to potential offenders for providing particular criminal opportunities.

A generator produces opportunities through ordinary concentrations of people; an attractor draws offenders because criminal opportunities are known to exist there.

The distance and travel pattern between an offender's activity locations and the places where offenses occur.

The general tendency for crime opportunities or offending frequency to decrease as travel distance increases, subject to contextual exceptions.

The possibility that some offenders avoid committing crimes immediately around their residence or another important anchor point.

An approach that reduces opportunities for specific offenses by modifying immediate environments, risks, rewards, and other situational conditions.

Ronald V. Clarke.

Increase effort, increase risks, reduce rewards, reduce provocations, and remove excuses.

Making an offense more difficult to carry out through measures such as access control or target hardening.

Increasing the perceived likelihood that offending will be observed, interrupted, or detected.

Reducing the expected benefit of an offense, such as by marking property or limiting access to valuables.

Reducing circumstances that may trigger conflict, frustration, temptation, or aggressive responses.

Clarifying rules and expectations so offenders have fewer opportunities to justify prohibited conduct.

Making a potential target more resistant to attack or unauthorized access through physical or technical security measures.

Designing spaces to increase ordinary visibility and observation by legitimate users.

Crime Prevention Through Environmental Design.

Natural surveillance, natural access control, territorial reinforcement, and maintenance or management.

Using design and legitimate occupancy to communicate ownership, responsibility, and appropriate use of a space.

The possibility that crime prevention in one setting shifts offending to another location, time, target, method, or offense type.

A reduction in crime beyond the directly protected targets or locations because preventive effects spread more widely.
