As cliometrics became more important in the 1950s and 1960s, the question of identity became more important too. One argument was that cliometricians should meet certain professional norms in history as well as in economics.

Others argued that economic historians should be gadflies, documenting crucial factors in growth and development that economic theory failed to appreciate. This argument is usually associated with Douglass North but it, too, had many adherents. Taken together, the two impulses created an intellectual space apart from the rest of the economics profession in which the early cliometricians, and their students, could function....

If this were to happen, the demand for specialists in economic history might dry up, to the point where obscure but critical knowledge becomes difficult to access or is even lost.
