Religious, Cognitive, & Personality Predictors of Intelligence Charla Leonard, Caleb W. Lack, Kathryn Schrantz, & Alisa M. Huskey University of Central Oklahoma Abstract This study used a culturally and educationally homogenous group to examine prediction of IQ scores. Participants were given an intelligence test and completed measures of religiosity, cognitive style, and personality. Results indicate that religious fundamentalism, certainty in the absence of a deity, need for cognition, openness, and are key predictors of IQ in an educationally homogenous group. Method Participants 84 Undergraduates at a metropolitan university GENDER. 69% were female AGE. Range 18 to 36; (M = 20.58; SD = 3.98) ETHNICITY. 65.5% were White; 13.1% were Black or African American; 8.3% were Asian RELIGIOUS AFFILIATION. 61.9% were Protestant; 8.3% were Catholic; 16.7% selected “None”; 13% were “Other” Procedure Undergraduates, recruited via Sona-Systems, participated in this research project for course credit. Research assistants administered the Wechsler Abbreviated Scale of Intelligence, second edition (WASI-II) to each participant. Subsequently, participants responded to questionnaires addressing demographics, general religiosity, religious fundamentalism, and a variety of demographic, cognitive, and personality variables Measures Wechsler Abbreviated Scale of Intelligence (FSIQ) Verbal Performance Religious Fundamentalism Scale Defensive Theology Scale Santa Clara Strength of Religious Faith Scale Dawkins Belief Scale Big Five Inventory (BFI) -Openness -Conscientiousness -Extraversion -Agreeableness -Neuroticism Need for Cognition Table 1 Correlations between Religious, Cognitive, and Personality Variables   1 2 3 4 5 6 7 8 9 10 1.

While many have reported on a negative relationship between being religious and intelligence, the methodology in studies of this potential relationship is incredibly variable. For instance, there has been very little consistency in the measures used to assess religious variables across studies, while measures of “intelligence” vary from tests designed specifically to measure intelligence, to measures designed to measure only a single aspect of intelligence (e.g., verbal skills), to measures that are more achievement-based (e.g., university entrance exams or GPA). Studies are needed that examine the diverse aspects of religiosity, use modern and well-constructed intelligence measures, and also examine a variety of demographic, cognitive, and personality variables find out which (alone or in combination) are related to any observed differences in intelligence between the religious and non-religious. Discussion Correlational analyses indicate that intelligence scores are inversely related to feelings of divine importance, religious fundamentalism, strength of religious faith and positively related to need for cognition, certainty in the absence of a deity, and openness to experience. Regression analyses* revealed the relative predictive power of these measures with IQ score, indicating that religious fundamentalism, need for cognition, certainty in theism, and the Big Five personality characteristics predicted 25% of the variance in IQ scores. These findings are consistent with previous literature and also provide further insight into some personality and cognitive characteristics underlying the religion and intelligence relationship. Results Hierarchical Multiple Regression Criterion: Full Scale IQ Score On step one, Religious Fundamentalism was entered, accounting for 10% of variance in intelligence, R2 = .10, F(1, 81) = 8.77, p = .004. On step two, Need for Cognition was entered, accounting for an additional 4% of the variance, R2 change = .041, F(2, 80) = 6.45, p = .003. On step three, Dawkin’s Belief Scale was entered, accounting for an additional 1% of the variance R2 change = .012, F(3, 79) = 4.69, p = .005. On step four, all Big Five personality characteristics were entered, accounting for an additional 10% of the variance, making the entire model account for 25% of variance in intelligence, R2 = .249, F(8, 74) = 3.07, p = .005. *To avoid multicollinearity between Dawkins Belief Scale, Defensive Theology, Religious Fundamentalism, and Strength of Religious Faith (r ranging from .71 to .85) only Dawkins was used in the regression analysis.
