Analysis of some studies that link political tendancies and factors like education level, how afraid we feel, and personality traits. "[A study] found that conservatives have a greater desire to reach a decision quickly and stick to it, and are higher on conscientiousness, which includes neatness, orderliness, duty, and rule-following. Liberals are higher on openness, which includes intellectual curiosity, excitement-seeking, novelty, creativity for its own sake, and a craving for stimulation like travel, color, art, music, and literature." And an interesting conclusion about the effects of rational thought on all this.
