Title PhD research:

Criminal law, Morality and Cognitive (Neuro)science: a longtermist perspective on the criminalization of behaviour


My research focuses on a fundamental question: what type of behaviour should be brought under the scope of the criminal law? From a philosophical perspective: what type of conduct should be considered good, or evil? I try to look at these questions from a new, cognitive (neuro)scientific perspective: how do our minds create notions of good and evil? And what happens in our brains when we think about right and wrong?

In my dissertation, I try to incorporate findings from moral psychology, cognitive (neuro)science and evolutionairy theory in traditional legal theory. The ultimate goal is to understand how our minds think about morality and the criminal law, and also: to understand how we can become better at thinking about it. Do insights from cognitive neuroscience help us in tackling pressing, longtermist, modern moral problems such as climate change, the dangers of A.I. and other (bio)technological developments?
