Explanation:

Deterrence theory states that preventing crime is possible only by effects of the threat of punishment, relying on the assumption that humans are motivated to avoid pain and obtain pleasure. Thus, deterrence can dissuade a criminal from taking action, based solely on a credible and certain threat of punishment. This psychological assumption is linked to rational choice theories.

The deterrence theory also states that severity of punishment will do little to deter crime and that certainty of punishment has a greater impact on crime deterrence than severity.
