Abstract: INTRODUCTION: No amount of practically successful "mental measurement" in laboratories, school-systems, factories or the army can relieve us, if we do not wish to waste time, of the necessity of stopping, every so often, to take account of first principles. Psychophysics, with more than half a century of history to its credit, has repeatedly found the need to eliminate its logically unfit and reorganize its forces: it is a long cry from the principle of the just noticeable difference to the principle of the psychometric function. The mental test as a new- comer had first to prove its right to consideration. Now that it has been accepted it must pass under the critical eye and learn to conform. And what needs to be said, in way of ad- monition, applies especially to the mental test, although for no other reason than that the mental test is the lustiest form of mental measurement that one meets today. It, especially, merits a discriminating encouragement.
