Big Five Personality Test

This free online 35-question personality test will allow you to obtain your scores on the Big Five traits, as well as to have your results cross-referenced with findings from social science research. The Big Five test is the most widely used personality test in social science and has sometimes been called "the only truly scientific personality test." Psychologists and researchers who favor it argue that the Big Five traits serve as dispositional signatures that shape the individual's responses to stimuli over time, thus leaving their mark on the person's behavior and attitudes, academic performance, political ideology, lifetime earnings, and even their health and longevity as well.

The CT-NEO-IP-III© is not the equivalent of the NEO PI-R, the IPIP-NEO, the CT-NEO-IP-II©, or the CT-NEO-IP©.

The IPIP-NEO is compiled by Lewis R. Goldberg, Ph.D. and professor of psychology, but in the public domain. The CT-NEO-IP© and the CT-NEO-IP-II© are the property of IDR Labs International.

The NEO PI-R is the property of Psychological Assessment Resources.

The CT-NEO-IP-III was compiled on the basis of peer-reviewed journal articles, not previously utilized for Big Five research on IDRLabs.com. These papers include: Gerber, A.S., Huber, G.A., Doherty, D., Dowling, C.M.: Personality Traits and the Consumption of Political Information American Politics Research 39(1), 2010; Gerber, A.S., Huber, G.A., Doherty, D., Dowling, C.M., Raso, C., Ha, S.E.: Personality Traits and Participation in Political Processes Journal of Politics, Volume 73, Issue 03, July 2011; Gerber, A.S., Huber, G.A., Doherty, D., Dowling, C.M.: Personality and the Strength and Direction of Partisan Identification Political Behavior 34, 2012; Iyer R., Koleva S., Graham J., Ditto P., Haidt J.: Understanding Libertarian Morality PLoS ONE 7(8), 2012; Mondak, J.J.: Personality and the Foundations of Political Behavior Cambridge University Press, 2010; and Vecchione, M., Alessandri, G., Barbaranelli, C., Caprara, G.: Gender Differences in the Big Five Personality Development Personality and Individual Differences, Volume 53, Issue 6, October 2012.

Although all are designed to measure the Big Five traits, the CT-NEO-IP-III© should not be confused with the IPIP-NEO or the NEO PI-R, as authored by Paul T. Costa, Jr. and Robert R. McCrae, however, both are personality tests (or inventories) for measuring traits within the Big Five or Five Factor Model (FFM) system of personality. The NEO PI-R is the property of Psychological Assessment Resources. The CT-NEO-IP-III© is the property of IDR Labs International.
