How Experts Think

Kevin Ashton recently wrote on Medium about How Experts Think. The main idea is that experts think faster and more efficiently than non-experts because they have acquired great doses of selective attention through years of practice. However the article doesn’t mention the mental models that experts develop through those years of practice. Those mental models are what allow them to filter out irrelevant stimuli and bad options. And they are important for another reason: once you can identify those mental models it’s easier for you to transfer your expertise to other people and to evaluate and reason about expertise itself.
