There is a new manuscript online which I will undoubtedly find interesting, I bet, once I find time to read its 52 pages (OK, double-spaced TXT with a long list of references and an Appendix of stats):
The Secret Lives of Liberals and Conservatives: Personality Profiles, Interaction Styles, and the Things They Leave Behind (pdf) by Dana R. Carney, John T. Jost, Samuel D. Gosling, Kate Niederhoffer and Jeff Potter.
ABSTRACT: Seventy-five years of theory and research on personality differences between political liberals and conservatives has produced a long list of dispositions, traits, and behaviors. Applying a “Five Factor Model” framework to this yield, we find that two traits, Openness to Experience and Conscientiousness, parsimoniously capture many of the ways in which individual differences underlying political orientation have been conceptualized. In four studies we investigate the relationship between personality and political orientation using multiple domains and measurement techniques, including: self-reported personality assessment; explicit beliefs, values, and preferences; nonverbal behavior in the context of social interaction; and personal possessions and the characteristics of living and working spaces. We obtained consistent and converging evidence that personality differences between liberals and conservatives are robust, replicable, and behaviorally significant. In general, liberals are more openminded in their pursuit of creativity, novelty, and diversity, whereas conservatives seek lives that are more orderly, conventional, and better organized.
So, you read it before me and tell me what you think…
