"Psychopaths with modest IQ's (90-100) frequently show an excellent ability to manipulate their environment, . . . whereas neurotics, with considerably higher IQ's, often fail badly in managing their own lives . . . The difference . . . is largely the result of differences in amount of non-intellective intelligence possessed by each." These non-intellective factors "include all affective and conative abilities which in any way enter into global behavior." Total intelligence cannot be measured until the tests also include some measures of the non-intellective factors. (PsycINFO Database Record (c) 2006 APA, all rights reserved)
