Polanyi's paradox, named in honour of the British-Hungarian philosopher Michael Polanyi, is the theory that human knowledge of how the world functions and of our own capability are, to a large extent, beyond our explicit understanding. The theory was articulated by Michael Polanyi in his book The Tacit Dimension in 1966, and economist David Autor gave it a name in his 2014 research paper "Polanyi's Paradox and the Shape of Employment Growth".[1]

Summarised in the slogan "We can know more than we can tell", Polanyi's paradox is mainly to explain the cognitive phenomenon that there exist many tasks which we, human beings, understand intuitively how to perform but cannot verbalize their rules or procedures.[2]
This "self-ignorance" is common to many human activities, from driving a car in traffic to face recognition.[3] As Polanyi argues, humans are relying on their tacit knowledge, which is difficult to adequately express by verbal means, when engaging these tasks.[2] Polanyi's paradox has been widely considered to identify a major obstacle in the fields of AI and automation, since programming an automated task or system is difficult unless a complete and fully specific description of the procedure is available.[4]
