What is the main conflict in Incognito: The Secret Lives of the Brain by David Eagleman?

In Incognito, David Eagleman, a neuroscientist, presents his argument that the American criminal justice system should integrate current research in brain science into sentencing guidelines. Assigning blame for criminal acts is complicated by the fact that our actions are dictated to a great extent by our unconscious minds, Eagleman claims. He proposes that rather than sentencing criminals based on how culpable they appear to a judge or jury, sentencing should be based on a person's potential for reforming their behavior based on neurological factors.
