Started off as a dry but interesting exploration of subconscious activity. However, Eagleman sneakily shifted to use his research to defend a thesis on the treatment, not punishment, of criminals. While he makes some good points about our current criminal justice system, I don't necessarily agree with this premise, since it relies on the notion that murder is like Tourette's, an impulse that people lack any control over. I would have given it 3 stars but the way he writes comes across as manipulative, and I don't necessarily trust that he presented a balanced picture of the science.
