The reasoning for this is that humans are inherently afraid of death, thus discouraging people from committing capital crimes. This thought process does not take into account people with severe personality or mental disorders who do not have the emotional range to feel regret or empathy, or people who are committing crimes with connections to terrorist groups who believe they are working for a higher power. Still, people cling to the idea that the death penalty must be deterring crime. Ernest Van Den Haag, PhD, claims that with common sense it is easy to tell that the death penalty will deter crime rates. People in prison fear death much more than they fear life, since criminals prefer a life sentence to a death sentence. (qtd.in"Top 10 Pros and Cons") Is there any factual evidence to support this, though? With the data of around 3,000 counties, Emory Professors, Hashem Dezhbakhsh, Paul H. Rubin, and Joanna M. Shepherd concluded that for every execution, there were 18 less murders from 1977 to 1996. (Muhlhausen) How they came to this conclusion is unclear. In the write-up of their experiment, ‘Does Capital Punishment Have a Deterrence Effect? New Evidence from Post-moratorium Panel Data’, it is merely stated that they “[examined] the deterrent effect of capital punishment using a system of simultaneous equations and county-level panel data that cover the post-moratorium period” without a clear explanation of how that worked. It is unclear on whether capital punishment really serves as a deterrence to crime at
