Merz et al. (2022) reported a normal distribution of International Cognitive Ability Resource scale scores and positive correlations with level of education, income, and a self-estimate of intelligence. There were no gender differences on the total score.
Lace and Evans
(2021) found an inverse correlation between spirituality and intelligence using
the ASPIRES-SF and the ICARS-16 (r = -0.22 for ASPIRES-SF-R and -0.11 for ASPIRES-SF-S).
Lace and Evans
(2021) also reported mean IQ scores using ICAR-16 for religious and nonreligious
adults. Those who identified as only religious obtained the lowest intelligence scores. The total ICAR-16 intelligence scores are reported by category identity below. See
Table 2 in their article for score details.
Religious =
92.99
Spiritual =
99.37
Religious
& Spiritual = 98.86
Not
religious or spiritual = 103.73
The effect
size comparing Religious and Not religious = .73
