Secular changes in personality: An age-period-cohort analysis [link]Paper  doi  abstract   bibtex   
There has been a surge in media interest regarding the generational effects on the distribution and structure of personality traits. This article examines time and generational effects on the Five Factor personality traits. Hierarchical Age-Period- Cohort Modeling (HAPC) was deployed on a sample of 30,722 participants assembled from pooled repeated cross-sectional data collected between 2006 and 2018. After controlling for both age and period effects no generation-related effects in personality traits (both aggregate and facet levels) were detected. Our findings imply that broad societal changes delineating various “generations” exert a minor influence over the distribution of personality traits in the general population.
