Abstract: Over the years an impression has arisen that personality profiles, such as those produced by the graphical representation of an individual's scores on the Personality Research Form (PRF) and the Minnesota Multiphasic Personality Inventory (MMPI), commonly occur among normal individuals with as many as five or six significant scale elevations and/or depressions.The more elevations and/or depressions a profile exhibits, the more "articulated" it is.This study attempted to establish base rates for the occurrence of articulated profiles on the PRF and the MMPI and to determine what, if any, profiles are commonly exhibited.Profile scale elevations and/or depressions were examined using three criterion levels:two-standard deviations from the mean, one-and-one-half-standard deviations from the mean, and one-standard deviation from the mean.Gender differences and age influences were examined in relationship to commonly exhibited profiles, both articulated and non-articulated.Also of interest, was whether there was any relationship between patterns of elevations and/or depressions on the PRF and the MMPI.Results indicated that at the two-standard deviation criterion, very few subjects exhibited articulated profiles on either the PRF or the MMPI and common profiles with more than one elevation and or depression did not exist.The majority of subjects exhibited profiles with zero elevations and/or depressions.When the criterion was lowered to oneand-one-half-and then one-standard deviations, more articulated profiles were exhibited.However, a set of commonly exhibited profiles did not emerge.In addition, articulated profiles on one instrument were not predictive of articulated profiles on the other.These results have major implications for Western ideas of individuality and the question of whether people are unique or whether there are common personality types.
