Jonathan works in moral psychology, which means that he is concerned with understanding the psychological concepts employed in ethical discourse, with the extent to which these concepts are genuinely applicable to people, and with ways in which our moral thinking can go wrong when we make mistakes about human psychology.

His most recent publications have been concerned with the ideas of character and virtue, particularly with whether empirical psychology has shown these to embody a mistaken view of human behaviour, and with clarifying and assessing the theory of the origins and nature of character at the heart of twentieth-century French existentialist thought.

He is currently working on ways in which moral psychology can be applied directly to current debates in applied ethics.
