An examination of genetic and environmental factors related to negative personality traits, educational attainment, and economic success.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Personality variables are associated with educational attainment and socioeconomic outcomes. In this study we incorporated a polygenic score derived from the largest genome-wide association study (GWAS) of educational attainment to date (Lee et al., 2018) into the Interactionist Model of R. D. Conger, Martin, and Masarik (2021) that describes the influence of socioeconomic factors on individual development. The inclusion of a polygenic score predictive of educational attainment (PS-Edu) into this model, and the use of the multigeneration, longitudinal Family Transitions Project (FTP) provide a unique opportunity to investigate genetic and environmental influences on the development of negative personality traits and educational and economic outcomes. The FTP is a three-generation sample. This study utilized data from the first generation (G1; mean age 40 at initiation of the FTP) and second generation (G2; assessed at mean ages 18 and 30). Participants are approximately 50% female, 99% of European ancestry, primarily from lower to middle class SES. PS-Edu was significantly correlated with educational attainment in both generations of the FTP, accounting for 4.1 to 6.7% of the variance. Findings confirm that PS-Edu is a complex genetic index that is correlated with all of the socioeconomic constructs in the model. Results suggest potential gene-environment correlation or common genetic influences underlie associations among parenting investments, negative personality traits, and educational attainment. Genetic variance captured by PS-Edu was mediated substantially through G1 parental investments. Although study limitations warrant cautious interpretation, we demonstrate the promise of including polygenic scores in developmental models to better understand genetic and environmental influences on human development.
