Jm. Hunt et al., DELIBERATIVE VS DISINGENUOUS SUBJECTS ON THE SOCIAL DESIRABILITY OF NEED FOR COGNITION, Perceptual and motor skills, 77(1), 1993, pp. 95-98
Petty and Cacioppo's need for cognition scale (NCS)-both long version
and short version-correlated significantly with the social desirabilit
y scale of Crowne and Marlowe. Inasmuch as need for cognition is an im
portant individual-difference variable in Petty and Cacioppo's elabora
tion likelihood model of attitude change, caution seems warranted when
ever this model is used in settings associated with cognitive achievem
ent, lest subjects disingenuously feign cognitive need in a socially d
esirable attempt to appear ''smart'' or deliberative.
