While genetics plays a significant role in the lifestyles that twins choose based on them having, in this case, a completely identical genetic makeup, it is not the only thing to take into consideration. Backlash on the idea of criminality concordance rates being high in twins came from criticism stating “identical twin children are typically dressed the same by their parents, as well as treated the same by the public. In other words, they are not only treated the same by society but also generally expected to behave the same.” (Schram & Tibbetts, 2020, p.132).

While serving in prison, Stephen made the comment of “I thought I was the only murderer in the family” (Schram & Tibbetts, 2020, p. 129) which serves to tell us they did not collaborate about the crimes they committed.
