For the average person, the criminal justice system can be a bureaucratic and confusing process. It is for exactly these reasons, many defendants will choose to spend exorbitant amounts of money to prove their innocence or hide their guilt. Therefore, when thinking from an economic perspective, one begins to wonder whether or not the vast amounts of money allocated to building a legal defense, actually have statistical impact on the outcome of the sentence. Or, if perhaps it is the characteristics of the defendant, the case, or the judge that truly account for the determination of the final verdict.

ABSTRACT Research on self-control theory (Gottfredson & Hirschi, 1990) consistently supports its' central proposition that low self-control significantly affects crime. The theory includes other predictions, which have received far less empirical scrutiny. Among these is the argument that self-control is developed early in childhood and that individual differences then persist over time. Gottfredson and Hirschi contend that once established by age ten, self-control remains relatively stable over one's life-course (stability postulate). To determine the empirical status of Gottfredson and Hirschi's "stability postulate," a meta-analysis on existing empirical studies was conducted. Results for this study support the contentions made by Gottfredson and Hirschi, however the inclusion of various moderating variables significantly influenced this relationship. Keywords: self-control, self-control stability, absolute stability, relative stability
