The Constructed Type
The constructed type is an outgrowth of the ideal type, as discussed primarily by Becker (1940) and McKinney (1954, 1966). It differs from the ideal type in that the constructed type is generally not an extreme or accentuated form of the type, but is rather a more common or central empirical form. As defined by McKinney, a constructed type is a:
purposive planned selection, abstraction, combination and (sometimes) accentuation of a set of criteria with empirical referents that serve as a basis for comparison of empirical cases. (McKinney, 1966, p. 3. Italics in the original)
McKinney states further that:
The comparison and measurement of empirical approximations reveal nothing but deviations from the construct. Nothing but "exceptions" to the constructed types exist. This is not only to be expected but is to be sought after for it is the basis of the typological method. (McKinney, 1954, p. 145)
