American on-line atheists and psychological type

A sample of 10,627 American atheists (7763 males and 2864 females) completed the Francis Psychological-Type Scales as part of the Personality and Belief in God Survey on-line. Compared with USA population norms, both male and female atheists displayed significantly higher levels of preference for introversion, thinking, and judging. The two predominant types among female atheists were ISTJ (40.8%) and INTJ (11.7%), compared with 6.9% and 0.8% respectively in the wider population. The two predominant types among male atheists were also ISTJ (41.4%) and INTJ (14.4%), compared with 16.4% and 3.3% respectively in the wider population. These large over-representations suggest that certain psychological types are much more likely to embrace atheism than others. Additional research is needed in order to test this hypothesis further.
