Why deterrence doesnt work

Their desperation is the most important thing. Burglars, for instance, generally avoided houses where they thought people might be home, Wright, now professor and chair of criminal justice and criminology at Georgia State University, also told me. They were afraid of what might happen if they went in. That matches up with what Daniel Nagin, a criminologist and statistician at Carnegie Mellon, has learned about deterrence strategies.

We really have no idea whether the presence of the death penalty increases homicides, decreases homicides, or has no effect at all, he told me. This is, essentially, the same place the research sat back in when the National Research Council issued a report heavily critiquing the methods used in a study that claimed each execution deterred seven or eight homicides. There were many problems with that study, and many with the studies that have come since. There are just too many moving parts involved in that risk analysis, from the local political climate, to the number of previous executions in a given state and, thus, the data available to analyze.

Risk of conviction is also a separate matter from the risk of being sentenced to execution — both of which are distinct from the perceived risk of actually being executed. Expecting anyone to have an accurate grasp of this complex matrix of risks and consequences is preposterous, Nagin said. Research does show, however, that you can deter crime by nudging would-be criminals to weigh the odds of getting caught in the first place. Like the St. Louis burglars, most people are going to avoid committing crimes in situations where somebody is likely to catch them.

In one randomized experiment from , researchers randomly assigned increased police presence to some Minneapolis hot spots. The areas that received the intervention saw a 6-to percent reduction in crime calls. This article sets out the current relevance of general deterrence to the sentencing calculus. It then examines the empirical data regarding the efficacy of punishment to deter offenders, and makes suggestions for reform in light of these empirical findings.

Swinburne Research Bank. Marginal general deterrence doesn't work - and what it means for sentencing. Abstract General deterrence is broadly understood as the theory that correlates increased sanctions with decreased crime rates. Publication year This is especially relevant given that death penalty use has been declining dramatically. Most states are not carrying out any executions in a given year. DPIC has collected many of the deterrent studies that have been conducted in the modern era and has summarized their results.

It also provides some of the raw data on which such studies rely, such as the murder rate for each state in each year in the modern era, along with the number of executions and death sentences for each state in the same periods.
