9781332179695: Porteus Tests the Vineland Revision (Classic Reprint)

Excerpt from Porteus Tests the Vineland Revision

Reports of the recent army examinations show that a large proportion of men were rated by the tests as being of very low grade intelligence.

Taking the sum of percentages of the above ratings we find that the percentage left for "D minus" is between 7 and 13 per cent.; hence, it would be no exaggeration to say that probably 10 per cent, have mental ages below what have been the commonly accepted lower limits of normality. Yet the great majority of these men have been, presumably, functioning satisfactorily in society. In any case, there is a vast discrepancy between this estimate and the number of feeble-minded in the population as determined by surveys. The estimates by surveys range from .3 to 1% of the population feeble-minded. Even if the men below ten years mentally were only five percent, of the men examined there is an unaccountable difference between the two estimates.

Either the limits of moronity have been placed too high, or, as an alternative, we must admit that tested intelligence below ten years is not always indicative of social unfitness.
