I went over this once already.

The actual report can be found here.

An excerpt, slightly reformatted:

"…[W]e consider evidence for and against the hypotheses that political conservatism is significantly associated with

(1) mental rigidity and closed-mindedness, including

(a) increased dogmatism and intolerance of ambiguity,

(b) decreased cognitive complexity,

(c) decreased openness to experience,

(d) uncertainty avoidance, (e) personal needs for order and structure, and (f) need for cognitive closure;

(2) lowered self-esteem;

(3) fear, anger, and aggression;

(4) pessimism, disgust, and contempt;

(5) loss prevention;

(6) fear of death;

(7) threat arising from social and economic deprivation; and

(8) threat to the stability of the social system.

We have argued that these motives are in fact related to one another psychologically, and our motivated social—cognitive perspective helps to integrate them. We now offer an integrative, meta-analytic review of research on epistemic, existential, and ideological bases of conservatism."

I can turn this list around many different ways, and I am having a great deal of difficulty trying to make it sound complimentary. The fact that the authors feel that some of these traits may have survival value is not much help. Being told that I am a pinhead is not softened by being informed that I can save money on hats.

And, as you might suspect, all this is your tax dollars at work.
