The concept of tacit knowing comes from scientist and philosopher Michael Polanyi. It is important to understand that he wrote about a process (hence tacit knowing) and not a form of knowledge. However, his phrase has been taken up to name a form of knowledge that is apparently wholly or partly inexplicable. Tacit knowledge cannot be captured, translated, or converted but only displayed and manifested, in what we do. New knowledge comes about not when the tacit becomes explicit, but when our skilled performance is punctuated in new ways through social interaction. Tacit knowledge - Knowledge that enters into the production of behaviors and/or the constitution of mental states but is not ordinarily accessible to consciousness.
