Information: - Expert is defined differently in varying academic fields. Psychology defines an expert using superior performance; sociology considers that expertise is a label given to an individual by a group and is interested in the power held by experts; philosophy stresses the kind of knowledge held by experts but not novices. Informally, an expert is someone widely recognized as a reliable source of technique or skill whose faculty for judging or deciding rightly, justly, or wisely is accorded authority and status by peers or the public in a specific well-distinguished domain. An expert, more generally, is a person with extensive knowledge or ability based on research, experience, or occupation and in a particular area of study. Experts are called in for advice on their respective subject, but they do not always agree on the particulars of a field of study. An expert can be believed, by virtue of credential, training, education, profession, publication or experience, to have special knowledge of a subject beyond that of the average person, sufficient that others may officially (and legally) rely upon the individual's opinion. Historically, an expert was referred to as a sage (Sophos). The individual was usually a profound thinker distinguished for wisdom and sound judgment. - Legal profession is a profession, and legal professionals study, develop and apply law.

The methodology of teaching is called pedagogy. - Of counsel is, in the legal profession of the United States, often the title of an attorney who has a relationship with a law firm or an organization, but is not an associate or a partner. Some firms use titles such as "counsel", "special counsel", and "senior counsel" for the same concept.
