- Kent Kiehl's brain research on psychopathy was used in the trial of serial killer Brian Dugan, marking early use of neuroscience in US courts.
- Despite brain scan evidence suggesting Dugan's psychopathy, he was sentenced to death, later commuted to life after Illinois' death penalty moratorium.
- From 2005 to 2015, brain evidence appeared in over 2,800 judicial opinions, influencing about 10-12% of murder trials and 25% of death-penalty cases.
- Kiehl founded Mindset, a private company that conducted brain scans for over 200 capital cases, including that of Amos Joseph Wells III.
- In Wells' trial, defense used brain scans and genetic testing to argue biological predisposition to violence, but the jury sentenced him to death.
- Critics argue criminal brain science revives discredited ideas like phrenology, ignores social factors like racism, and risks ethical issues in biased prison populations.
- Kiehl received over $41 million in NIH funding and lectured to federal judges, promoting neuroscience in courtrooms, despite concerns over overstatement of evidence.
- The case of Wells highlights risks of using biological determinism in court, as it may reinforce racist stereotypes and lead to harsher sentences.
- Research linking genes like MAOA to violence has been discredited, yet was presented in Wells' trial, raising questions about scientific validity and ethical standards.
- Kiehl's work continues, with recent studies on incarcerated populations, amid ongoing debate about the role of neuroscience in criminal justice.
