The evolutionary theory of Darwin or the Principles of Psychology of W. James are good examples of slow science. We can apply this dichotomy to any domain: think fast or slow (Khaneman book about systems 1 and 2 in any daily life domain, bussiness, homework, family...), fast food versus slow food, fast sex versus slow sex, fast education versus slow education, fast vs slow reading, task network versus neurological default network, automatic versus controlled ... In all domains it is important to find a good balance (different balance in different domains) between s1 and s2 . The importance of the question is its function to distinguish good versus bad science or sex or education...I think that the question is not so easy that the solution is only to choose one of the two systems, even it maybe a dimensional line and not just a dichotomy. But what about today's science? Is it dominated by s1?
