Should brain scans decide criminal intent?

We can now image the brain and see tumors, lesions, or abnormal activity. If a defendant has a brain abnormality, should that be admissible to argue they lacked criminal intent?

Yes as mitigating or explanatory evidence, not as a definitive decoder of intent. Neuroscience can inform assessments of mental capacity, impulse control, or diminished responsibility. But brain scans cannot yet (and may never) reliably answer the legal question: Did this defendant, at that moment, form specific intent? The law's definitions of mens rea involve moral and contextual judgment, not just neural correlates. Admit the science. Let it inform. But let the law, with all its imperfect human tools, make the final call.
