The Center for Law, Brain & Behavior puts the most accurate and actionable neuroscience in the hands of judges, lawyers, policymakers and journalists—people who shape the standards and practices of our legal system and affect its impact on people’s lives. We work to make the legal system more effective and more just for all those affected by the law.

WATCH – “Does Brain Difference Affect Legal & Moral Responsibility?”

Brains create behavior. Yet we hold people, not brains, morally and legally responsible for their actions. Under what conditions could – or should – brain disorder affect the way which we assign moral and legal responsibility to a person? 

In this conversation among a neuroscientist who studies moral judgment, a forensic psychiatrist, and a law professor, we explored three cases that highlight the relationship between brain disorder, law-breaking, and norms relating to responsibility.

Each case raised challenging questions: Can we establish whether the brain disorder caused the law-breaking behavior? Even if we can, is the presence of brain disorder morally or legally excusing? All behavior is caused: why should some causes be excusing, but not others? If brain disorder can cause unlawful behavior, can we infer the reverse – that people who behave unlawfully have disordered brains? A provocative discussion on the state of the art of the intersection of neuroethics, brain science, philosophy, and the law was had by all.

This seminar took place from 4:30-6:00pm on Monday, March 30 at Harvard Medical School.
