Using composite images of those scoring high and low on a particular trait, the current study shows that judges perform better than chance in guessing others' personality, particularly for the traits conscientiousness and extraversion.

like to blame politicians but the truth is, the way we go about picking our leaders is just as screwed up and disappointing.

Does darkness increase dishonesty?:
s, it does: via boston.com In several experiments, researchers found that light levels influence selfish behavior. People who were placed in a dimly lit room were significantly more likely to cheat than people placed in a well-lit room.

This pattern appears to be the result of an increased sense of anonymity in lower light levels, even…
