Editing Tacit knowledge (section)

==== 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.<ref>{{Cite book |last=Collins |first=Harry M. |url=http://worldcat.org/oclc/871293266 |title=Tacit and explicit knowledge |date=2013 |publisher=The University of Chicago Press |isbn=978-0-226-00421-1 |oclc=871293266}}</ref>
