The problem with our laws today is that they do not tell us what crime is. Not everyone agrees which actions are good or bad. A criminal to me is a hero to another. What laws do is give us a baseline that creates equilibrium between apposing view so that we can dismiss our differences and work towards shared goals. But what if in the future we discover the neuroscience of why people disagree so much. How will the law be affected by this discovery? Extremists politicians could use neuroscience to impose laws that everyone share the beliefs they want them to. They could use Neuro Propaganda on the weak minded for devious purposes. On the other had the non-extremists could help the weak minded to have strong minds to resist the extremists. I see two scenarios that could happen. A global Orwellian dictatorship or a global Age of Enlightenment. Question: How do we define extremism, how "should" we eliminate it with neuroscience?
