Abstract

To become an expert in a technical domain means acquiring the tacit knowledge pertaining to the relevant domain of expertise, at least, according to the programme known as “Studies of Expertise and Experience” (SEE). We know only one way to acquire tacit knowledge and that is through some form of sustained social contact with the group that has it. Those who do not have such contact cannot acquire the expertise needed to make technical judgments. They can, however, use social expertise to judge between experts or expert claims. Where social expertise is used to make technical judgments we refer to it as “transmuted expertise”. The various kinds of transmuted expertise are described and analysed
