What have we learned from an empirical approach to moral psychology - especially in relation to the role of rationality in most every day morality?
What are some lessons that the EA movement can take from moral psychology?
Various moral theorists over the years have had different emphasis on the roles that the head and heart play in moral judgement. Early conceptions of the role of the head in morality were that it drives moral judgement. A Kantian might say that the head/reasoning drives moral judgement – when presented with a dillema of some kind, the human engages with ‘system 2’ like processes in a controlled rational nature. An advocate of a Humean model may favor the idea that emotion or the heart (‘system 1’ thinking) plays the dominant role in moral judgement. Modern psychologists often take a hybrid model where both system 1 and system 2 styles of thinking are at play in contributing to the way we judge right from wrong.
