THE PRESENT INVESTIGATION WAS PREDICATED UPON THE ASSUMPTION THAT DOUBLE AGREEMENT (THE TENDENCY TO AGREE TO BOTH ORIGINAL AND REVERSED AUTHORITARIANISM ITEMS) IS A FUNCTION OF BOTH S AND ITEM CHARACTERISTICS. DOUBLE AGREEMENT ON F, ANTI-SEMITISM, AND DOGMATISM SCALES CORRELATED .88, .65, AND .83, RESPECTIVELY, WITH THE RATED AMBIGUITY OF THE ITEMS. THIS FINDING SUPPORTS THE POSITION TAKEN BY PEABODY AS OPPOSED TO ALTERNATIVES SUGGESTED BY ROKEACH AND SAMELSON. FURTHER, SCORES OF SS ON THE MARLOWE-CROWNE SOCIAL DESIRABILITY SCALE CORRELATED .36, .25, AND .44 WITH THEIR FREQUENCIES OF DOUBLE AGREEMENT ON THE 3 MEASURES. BOTH HYPOTHESES WERE SUPPORTED FOR EACH OF THE 3 TESTS AT THE .001 LEVEL. FINDINGS ARE DISCUSSED IN TERMS OF THE ROLE OF AMBIGUOUS MEASURES AND SOCIAL PRESSURES INDIGENOUS TO THE TESTING SITUATION AS FACTORS IN THE ERRONEOUS IDENTIFICATION OF AUTHORITARIANISM.
