The relationship between religious attitudes or orientations and prejudice was studied in a sample of 337 adults: college males, lay persons and ministers from local congregations, and seminary students in Louisiana and Texas. The study is based on Gordon Allport's theory concerning intrinsic and extrinsic religiousity. Ten religious groups were represented: Catholic; Episcopal, Methodist, Lutheran, Presbyterian, Christian/Church of Christ, Baptist, Pentacostal, Jewish, and Other. A 227-item test battery was constructed from the Committed-Nominal Religious Attitude Scale, Allport's Religious Orientation Scales, Religious Fundamentalism Scale, Altered Ethnocentrism Scale, Rokeach's Dogmatism Scale, and Crowne and Marlowe's Social Desirability Scale. Demographic variables included age, location, education, and social status. Correlational and multivariate analysis of variance showed that a general factor of religiousity, or of indiscriminantly pro-religious attitudes, was represented. This hypothetical pro-religious person is 35 or older, politically conservative, educated, and a church leader. Another profile, corresponding to Allport's extrinsic individual, was characterized as narrow-minded, less educated, lower middle class, and not a church leader. Results also suggested that the religious commitment and intrinsic nature of churchgoers increases with age. Further research using more valid tests was recommended. (Author/GDC)
