Abstract
In this essay, I home in on the difficulties with group-to-individual (G2i) inferences in neuroscience and how they impact the legal system. I briefly outline how cognitive shortcutting can distort legal decisions, and then turn my attention to G2i inferences, with a special focus on issues of intellectual disability and brain damage. I argue that judges and juries are not situated to appreciate the nuances in brain data and that they are required to make clinical decisions without clinical training. As a result, they effectively ignore those responsibilities and simply decide cases in virtue of what they already believe to be true. How judges actually make decisions in highstakes criminal cases is troubling, but they are also hamstrung in a variety of ways.
