Several studies support rational choice theory, the main supporting theory for right realism, Rettig gave students a scenario of an opportunity to commit a crime. He found the degree of punishment determined whether they said they would go ahead
Feldman found people made rational decisions. If a crime was considered low risk, high yield they said it would be worth committing
Bennett and Wright interviewed convicted burglars. The burglars considered the potential reward, difficulty of breaking in and risk of being caught. Risk was the most important factor influencing their decision to commit crime
Right realism explains opportunistic petty crimes such as theft
Rettig and Feldman's research was based on experiments which lack environmental validity. The result may not apply to real offenders
Bennett and Wright studied unsuccessful burglars. We don't know if successful burglars think the same way
Not all crime is the result of rational decisions. Violent crimes are impulsive
Offenders acting under the influence of drugs or alcohol may not be capable of making rational decisions
