Associations between genetic predisposition to mental health problems and academic achievement
BACKGROUND: Children's cognitive abilities play an important role throughout their academic career, but recent studies highlight the negative impacts of aggression, inattention, and impulsivity on academic success. These behaviors and traits are central to most externalizing (EXT) and neurodevelopmental (NDD) problems, which are substantially genetically influenced. We examined the mechanisms by which high levels of genetic predispositions to EXT…
Clarifying the structure and nature of left-wing authoritarianism
Authoritarianism has been the subject of scientific inquiry for nearly a century, yet the vast majority of authoritarianism research has focused on right-wing authoritarianism. In the present studies, we investigate the nature, structure, and nomological network of left-wing authoritarianism (LWA), a construct famously known as "the Loch Ness Monster" of political psychology. We iteratively construct a measure and data-driven conceptualization of…
Discovery of the first genome-wide significant risk loci for attention deficit/hyperactivity disorder
Attention deficit/hyperactivity disorder (ADHD) is a highly heritable childhood behavioral disorder affecting 5% of children and 2.5% of adults. Common genetic variants contribute substantially to ADHD susceptibility, but no variants have been robustly associated with ADHD. We report a genome-wide association meta-analysis of 20,183 individuals diagnosed with ADHD and 35,191 controls that identifies variants surpassing genome-wide significance in…

The Hierarchical Taxonomy of Psychopathology (HiTOP)
A hierarchical causal taxonomy of psychopathology across the life span
We propose a taxonomy of psychopathology based on patterns of shared causal influences identified in a review of multivariate behavior genetic studies that distinguish genetic and environmental influences that are either common to multiple dimensions of psychopathology or unique to each dimension. At the phenotypic level, first-order dimensions are defined by correlations among symptoms; correlations among first-order dimensions similarly define …
The Double-Edged Sword of Grandiose Narcissism
Recent research and theorizing suggest that narcissism may predict both positive and negative leadership behaviors. We tested this hypothesis with data on the 42 U.S. presidents up to and including George W. Bush, using (a) expert-derived narcissism estimates, (b) independent historical surveys of presidential performance, and (c) largely or entirely objective indicators of presidential performance. Grandiose, but not vulnerable, narcissism was a…

The role of language in concern and disregard for others in the first years of life
We examined the associations between language skills and concern and disregard for others in young children assessed longitudinally at ages 14, 20, 24, and 36 months, testing the hypothesis that language skills have a specific role (distinct from that of general cognitive ability) in the development of concern and disregard for others. We found that higher language skills predicted higher concern for others and lower disregard for others even aft…
Fearless dominance and the U.S. presidency
Although psychopathic personality (psychopathy) is marked largely by maladaptive traits (e.g., poor impulse control, lack of guilt), some authors have conjectured that some features of this condition (e.g., fearlessness, interpersonal dominance) are adaptive in certain occupations, including leadership positions. We tested this hypothesis in the 42 U.S. presidents up to and including George W. Bush using (a) psychopathy trait estimates derived fr…
The Cambridge Handbook of Violent Behavior and Aggression
From a team of leading experts comes a comprehensive, multidisciplinary examination of the most current research including the complex issue of violence and violent behavior. The handbook examines a range of theoretical, policy, and research issues and provides a comprehensive overview of aggressive and violent behavior. The breadth of coverage is impressive, ranging from research on biological factors related to violence and behavior-genetics to…

The Minnesota Transracial Adoption Study
There is a body of emerging research that investigates whether adopted adolescents are more likely to develop behavior problems than their biological counterparts. However, few investigations have considered whether there are differences among adoption groups as to the development of behavior problems. The purpose of this study was to explore differences in psychosocial adjustment among transracia adoptees, Caucasian adoptees, and their non-adopt…
Genetic and environmental influences on antisocial behavior
A meta-analysis of 51 twin and adoption studies was conducted to estimate the magnitude of genetic and environmental influences on antisocial behavior. The best fitting model included moderate proportions of variance due to additive genetic influences (.32), nonadditive genetic influences (.09), shared environmental influences (.16), and nonshared environmental influences (.43). The magnitude of familial influences (i.e., both genetic and shared …
