Readers SFG and HBD Chick suggested that I compare the personality traits of agnostics with non-agnostics (MIDUS data, sample size = 3,960).
Cohen's d .49
Cohen's d .44
Cohen's d .29
Openness to experience
Cohen's d .50
*Agnostics and others are significantly different
Compared to the general population, agnostics are more introverted, less agreeable, less conscientious, and more open. They are like atheists, only shy and neurotic.
