Knowing what is true is valuable, but practical knowledge - knowledge of how to do things - is equally critical. Having such ‘know-how’ enables us to succeed in action and achieve our goals. Currently, little consensus exists about the nature of know-how and what is involved in exercising it. These barriers hinder our ability to recognise and utilise know-how effectively.KNOW-HOW is a major research project funded by the European Research Council (AdG 101199255) which aims to make a major advance here by developing a comprehensive framework for understanding know-how and its place in a wider web of concepts we rely on to understand and describe intelligent behaviour. The project will put our understanding of know-how on a new footing, impacting academic research across disciplines.
