Are highly heritable attitudes more or less complex than less heritable attitudes? Over 2,000 participant responses on topics varying in heritability were coded for overall integrative complexity and its 2 subcomponents (dialectical complexity and elaborative complexity). Across different heritability sets drawn from 2 separate prior twin research programs, the present results yielded a consistent pattern: Heritability was always significantly positively correlated with integrative complexity…

In Search of the Cognitively Complex Person: Is There a Meaningful Trait Component of Cognitive Complexity?

The literature suggests that persons’ cognitive complexity at any point in time results partially from a stable and generalizable trait component that accounts for a small-to-moderate amount of variance.

Are Conservatives Really More Simple-Minded than Liberals? The Domain Specificity of Complex Thinking

Prior research suggests that liberals are more complex than conservatives. However, it may be that liberals are not more complex in general, but rather only more complex on certain topic domains

Ideologically Motivated Perceptions of Complexity

While prior research has found linguistic complexity to be predictive across multiple domains, little research has examined how people perceive—or misperceive—linguistic complexity when they

Cueing Complex Thought

Content Does exposure to a complex description subsequently cue a person to be more complex? To test this question, participants read a paragraph about a specific topic. Paragraphs varied in their

An Integrative Complexity Analysis of Religious and Irreligious Thinking

Stereotypical views cast religious believers as closed-minded, unthinking individuals, and irreligious persons as comparatively more intellectual and complex. But are these perceptions accurate? To

Automated Integrative Complexity

A novel automatedIntegrative complexity system designed specifically from the integrative complexity theoretical framework is developed, which consistently showed modest relationships with human-scored Integrative complexity, and provides the best automatedintegrative complexity measurement to date.

Two ways to be complex and why they matter: implications for attitude strength and lying.

The authors argue that this dual demonstration across 2 different theoretical domains helps establish the utility of the new model and measurements as well as offer the potential to reconcile apparent conflicts in the area of cognitive complexity.

The heritability of attitudes: a study of twins.

The genetic basis of individual differences in attitudes was examined in a survey of 195 pairs of monozygotic twins and 141 pairs of same-sex dizygotic twins, and several possible mediators of attitude heritability correlated at a genetic level with the heritable attitude factors.

Heritability of Attitudes Constrains Dynamic Social Impact

Three studies tested the hypothesis that there are genetic constraints on group-level self-organization. In Study 1, an analysis of archival data reported in Eaves, Eysenck, and Martin showed that

Cultural Evolution: Interpersonal Influence, Issue Importance, and the Development of Shared Attitudes in College Residence Halls

The results suggest that intrapsychic processes as well as interpersonal processes contribute to cultural evolution, and support the predictions of dynamic social impact theory.

Attitude heritability and attitude reinforcement: A replication.


It is concluded that it is typically misleading to suggest monolithic cross-cultural differences for complexity of thought, and an interactionist approach appears more appropriate.

Genes, culture, and personality : an empirical approach

The "model" represents the bridge between theory and data, by translating the "semantic" components of a theory into "syntactic" definitions so that the rules of logical and mathematical inference can be used to deduce new predictions about the results of empirical studies.

Job Satisfaction: Environmental and Genetic Components

Monozygotic twins reared apart from an early age were used to test the hypothesis that there is a significant genetic component to job satisfaction. Thirty-four monozygotic twin pairs who had been
