Overview


Origin

The term tacit knowing is attributed to

He states not only that there is knowledge that cannot be adequately articulated by verbal means, but also that all knowledge is rooted in tacit knowledge. While this concept made most of its impact on

Definition

''Tacit knowledge'' can be defined as skills, ideas and experiences that are possessed by people but are not codified and may not necessarily be easily expressed. With tacit knowledge, people are not often aware of the knowledge they possess or how it can be valuable to others. Effective transfer of tacit knowledge generally requires extensive personal contact, regular interaction, and trust. This kind of knowledge can only be revealed through practice in a particular context and transmitted through

Terrain

Tacit knowledge can be divided according to the terrain. Terrains affect the process of changing tacit knowledge into explicit knowledge. Terrains are of three kinds: * ''Relational tacit knowledge:'' Relational tacit knowledge could be made explicit, but not made explicit for reasons that touch on deep principles that have to do with either the nature or location of knowledge of the way humans are made. This knowledge refers to things we could describe in principle if someone put effort into describing them. * ''Somatic tacit knowledge:'' Somatic tacit knowledge has to do with properties of individuals bodies and brains as physical things. It includes things our bodies can do but we cannot describe how, like riding a bike. In principle it is possible for it to be explicated as the outcome of research done by human scientists. * ''Collective tacit knowledge:'' Collective tacit knowledge is a kind of knowledge that we do not know how to make explicit and that we cannot envisage how to explicate. It is the domain of knowledge that is located in society, such as the rules for language - it has to do with the way society is constituted.


Embodied knowledge

Tacit knowledge has been described as “

s). This distinction between “know-how” and “know-what” is considered to date back to a 1945 paper by
Gilbert Ryle Gilbert Ryle (19 August 1900 – 6 October 1976) was a British philosopher, principally known for his critique of Cartesian dualism, for which he coined the phrase " ghost in the machine". Some of Ryle's ideas in philosophy of mind have been ca ...

s (“know-what”), and therefore the view that some knowledge can only be defined as “know-how”. Ryle's argument has, in some contexts, come to be called " anti-intellectualist". There are further distinctions such as "know-why" (science) or "know-who" (networking). Tacit knowledge involves learning and skill but not in a way that can be written down. On this account, knowing-how or “embodied knowledge” is characteristic of the expert, who acts, makes judgments, and so forth without explicitly reflecting on the principles or rules involved. The expert works without having a theory of his or her work; he or she just performs skillfully without deliberation or focused attention.

Differences from explicit knowledge

Although it is possible to distinguish conceptually between
explicit Explicit refers to something that is specific, clear, or detailed. It can also mean: * Explicit knowledge, knowledge that can be readily articulated, codified and transmitted to others * Explicit (text), the final words of a text; contrast with inc ...
and tacit knowledge, they are not separate and discrete in practice. The interaction between these two modes of knowing is vital for the creation of new knowledge. Tacit knowledge can be distinguished from explicit knowledge in three major areas: Polanyi, Michael. 1958. ''Personal Knowledge: Towards a Post-Critical Philosophy''. Chicago: University of Chicago Press. . * ''Codifiability and mechanism of transferring knowledge'': Explicit knowledge can be codified (for example, 'can you write it down' or 'put it into words' or 'draw a picture'), and easily transferred without the knowing subject. In contrast, tacit knowledge is

and unarticulated knowledge that cannot be communicated, understood or used without the 'knowing subject'. Unlike the transfer of explicit knowledge, the transfer of tacit knowledge requires close interaction and the buildup of shared understanding and trust among them. * ''Main methods for the acquisition and accumulation'': Explicit knowledge can be generated through
logical deduction Deductive reasoning is the process of drawing valid inferences. An inference is valid if its conclusion follows logically from its premises, meaning that it is impossible for the premises to be true and the conclusion to be false. For example, the ...
and acquired through practical experience in the relevant context. In contrast, tacit knowledge can only be acquired through practical experience in the relevant context. * ''Potential of aggregation and modes of appropriation'': Explicit knowledge can be aggregated at a single location, stored in objective forms, and appropriated without the participation of the knowing subject. Tacit knowledge, in contrast, is personal and contextual; it is distributed across knowing subjects, and cannot easily be aggregated. The realization of its full potential requires the close involvement and cooperation of the knowing subject. The process of transforming tacit knowledge into explicit or specifiable knowledge is known as codification, articulation, or specification. The tacit aspects of knowledge are those that cannot be codified, but can only be transmitted via training or gained through personal experience. There is a view against the distinction, where it is believed that all

and is thus known as the Nonaka–Takeuchi model. In this model, tacit knowledge is presented variously as uncodifiable ("tacit aspects of knowledge are those that cannot be codified") and codifiable ("transforming tacit knowledge into explicit knowledge is known as codification"). This ambiguity is common in the

Examples

* One of the most convincing examples of tacit knowledge is
facial recognition Facial recognition or face recognition may refer to: *Face detection, often a step done before facial recognition *Face perception, the process by which the human brain understands and interprets the face *Pareidolia, which involves, in part, seein ...
: one knows a person's face, and can recognize it among a thousand, indeed a million. Yet, people usually cannot tell how they recognize that face, so most of this cannot be put into words. When one sees a face, they are not conscious about their knowledge of the individual features (eye, nose, mouth), but rather see and recognize the face as a whole. * Another example of tacit knowledge is the notion of

). Western scientists became suspicious of the Russian results and it was only when Russian and Western scientists conducted the measurements collaboratively that the trust was reestablished. Collins argues that laboratory visits enhance the possibility for the transfer of tacit knowledge. * The Bessemer steel process is another example:

In the end, Bessemer set up his own steel company because he knew how to do it, even though he could not convey it to his patent users. * When Matsushita (now Panasonic) started developing its automatic home bread-making machine in 1985, an early problem was how to mechanize the dough-

process, a process that takes a master baker years of practice to perfect. To learn this tacit knowledge, a member of the software development team, Ikuko Tanaka, decided to volunteer herself as an apprentice to the head baker of the Osaka International Hotel, who was reputed to produce the area's best bread. After a period of imitation and practice, one day she observed that the baker was not only stretching, but also twisting the dough in a particular fashion ("twisting stretch"), which turned out to be important in the success of his method. The Matsushita home bakery team drew together eleven members from completely different specializations and cultures: product planning, mechanical engineering, control systems, and software development. The "twisting stretch" motion was finally achieved by a prototype machine after a year of iterative experimentation by the engineers and team members working closely together, combining their explicit knowledge. For example, the engineers added ribs to the inside of the dough case in order to hold the dough better as it is being churned. Another team member suggested a method (later patented) to add yeast at a later stage in the process, thereby preventing the yeast from over-fermenting in high temperatures.
