Protestant ethic endorsement, personality, and general intelligence

To learn if Protestant ethic endorsement predicted intelligence controlling for the big five personality factors, 364 college students from England and the United States completed a 65-item multifaceted work ethic endorsement measure, the 50-item Wonderlic Personnel Test, and a 60-item measure of the big five personality factors. A hierarchical multiple regression revealed that, after controlling for respondent's sex and the big five, work ethic facets accounted for 5.6% of the variability in Wonderlic scores. However, the direction of the relationship between PWE facets and Wonderlic scores depended on the PWE facet in question. Furthermore, the facets accounted for more variability than did a composite work ethic score. The discussion focuses on the multidimensional nature of PWE endorsement and future research with this construct.
