This article will explore several areas in which judges, hampered by their mathematical ignorance, have permitted numerical analysis to subvert the goals of our legal system. In Part II, I will examine the perversion of the presumption of innocence in paternity cases, where courts make the counter-factual assumption that regardless of the evidence, prior to DNA testing, a suspect has a 50/50 chance of being the father. In Part III, I will explore the unnecessary injection of race into trials involving the statistics of DNA matching, even when race is entirely irrelevant to the particular case. Next, in Part IV, I will discuss how courts use race- and gender-based statistics to reduce damages in tort cases for women and racial minorities, and silently assert that past racism and sexism will continue. In the final section, I will examine how judges have improperly allocated the risk of error in cases such as securities fraud, so as to reward those who have attempted to manipulate stock prices illegally.
