Tacitiedon, literally tacit knowledge in Finnish, refers to knowledge that is difficult to articulate, codify, or transfer through written or spoken language. It is knowledge that resides in personal experience, context, and know-how, often embedded in routines, skills, and intuition rather than in formal specifications.

The concept originated with the epistemological ideas of Michael Polanyi, who argued that “we know more than we can tell.” In this view, knowledge is partly personal and tacit, making it hard to transfer by simply writing it down. Tacitiedon is typically contrasted with explicit knowledge, which can be documented, stored, and communicated more easily.

Tacitiedon is often categorized as knowing how (procedural skills) and knowing why or patterns (cognitive insights that guide judgment). Examples include the intuitive ability of a skilled craftsman, a doctor’s diagnostic sense developed through experience, or a musician’s feel for timing. These forms of knowledge are frequently learned through apprenticeship, practice, and social interaction rather than formal instruction.

Transfer and conversion of tacitiedon into explicit knowledge face practical challenges. Socialization, mentoring, storytelling, and communities of practice are common methods for sharing tacit insights. Externalization efforts aim to codify tacit knowledge into manuals, checklists, and best practices, but such codification can be partial or imperfect.

In organizations, tacitiedon is recognized as a critical asset for performance and innovation, yet its fragility—especially when experienced workers leave—poses management challenges. Knowledge-management approaches seek to sustain tacitiedon through culture, collaboration, and processes that encourage reflection and practice. Some scholars note that the boundary between tacit and explicit knowledge is porous, with some tacit insights being articulable in certain contexts.
