“…It should be noted that there has been no systematic investigation of the Brunswik symmetry principle with regard to personality-intelligence relations. In combination with a lack of theoretical expectations about most of the combinations under investigation (for some exceptions, see e.g., References [42,52,53,54]), we thus consider the present study as exploratory. In fact, it is not even clear whether the hierarchical structure of intelligence and personality are congruent (i.e., whether the highest level of intelligence corresponds to the highest level of personality, see Figure 2).…”

The Relation of Personality and Intelligence—What Can the Brunswik Symmetry Principle Tell Us?

Personality and intelligence are defined as hierarchical constructs, ranging from broad g-factors to (domain-)specific constructs. The present study investigated whether different combinations of hierarchical levels lead to different personality-intelligence correlations. Based on the integrative data analysis approach, we combined a total of five data sets. The focus of the first study (N = 682) was an elaborated measurement of personality (NEO-PI-R), which was applied with a relatively short intelligence test (Intelligence Structure Test 2000 R). In the second study (N = 413), a comprehensive measurement of intelligence (Berlin Intelligence Structure test) was used with a shorter personality questionnaire (NEO-FFI). In line with the Brunswik symmetry principle, the findings emphasize that personality-intelligence correlations varied greatly across the hierarchical levels of constructs considered in the analysis. On average, Openness showed the largest relation with intelligence. We recommend for future studies to investigate personality-intelligence relations at more fine-grained levels based on elaborated measurements of both personality and intelligence.

“…There is also evidence from genetically informative samples indicating that g and GFP are unrelated at the genetic level. Loehlin, Bartels, Boomsma, Bratko, Martin, Nichols and Wright [61] studied a sample of monozygotic ( n = 1748) and dizygotic (1329) twin pairs from different countries. The genetic correlation between GFP and g was zero.…”

The Dissociation between Adult Intelligence and Personality with Respect to Maltreatment Episodes and Externalizing Behaviors Occurring in Childhood

Abstract:Here we analyze the simultaneous relationships among five variables. Two refer to childhood (episodes of various forms of maltreatment and externalizing behaviors), whereas three refer to early adulthood (intelligence, personality, and socialization difficulties). The 120 individuals considered for the present report were invited from the 650 schoolchildren participating in the Longitudinal Study of Intelligence and Personality (Minas Gerais, Brazil). The complete sample was recruited in 2002 (T1; mean age = 10.0; standard deviation (SD) = 2.2) and 120 were tested again in 2014-17 (T2; mean age = 23.5; SD = 2.2). Externalizing behaviors were registered at T1, whereas the remaining variables were obtained at T2. These were the main results: (1) externalizing behaviors predict future social effectiveness (as estimated by the general factor of personality derived from the NEO Personality Inventory-Revised (NEO-PI-R) and socialization difficulties computed from the socialization scale (SOC)) and future intelligence performance (as assessed by a set of fluid and crystallized tests); (2) episodes of self-reported childhood maltreatment predict social effectiveness, but not intelligence; (3) maltreatment and externalizing behaviors are unrelated; and (4) social effectiveness (personality) and intelligence are unrelated. Therefore, the findings support the dissociation between adult intelligence and personality with respect to maltreatment episodes and externalizing behaviors occurring in childhood. Implications of these findings for social policies aimed at preventing adult socially ineffective personalities are underscored.

“…Using the California Personality Inventory (CPI) and Minnesota Multiphasic Personality Inventory (MMPI) to assess the GFP and the California Achievement Test Battery (CATB), General Test Battery (GTB) to assess g. significant correlations were found between the g and the GFP tests with the largest correlation being with the CATB and CPI (.35). Loehlin et al (2015) examined for the presence of a genetic correlation between g and the GFP using data from US, UK, Croatian, Dutch and Australian twin samples. Various tests of personality and intelligence were used across the samples.…”

From general factors to response generalisation: the importance of the cerebellum for mental health and social effectiveness

Various psychometric general factor models exist to describe a diverse range of human psychological traits e.g. general factors of intelligence, personality and psychopathology. Historically, these latent traits have been viewed and studied as distinct constructs. However, accumulating evidence demonstrates empirical overlap, and conceptual proposals have been made arguing that collectively these traits form a marker of general social effectiveness. Here I argue that the cerebellum has an important, and previously neglected role in supporting diverse general factor psychological traits that enable such social effectiveness. In this conceptual article, I review evidence derived largely from neuroimaging studies, that these general traits (intelligence, personality, psychopathology and others) share overlapping neural correlates, and potentially shared underlying computations in the cerebellum. This is important as the cerebellum has an integrative role in skilled behaviour and psychological flexibility by enabling cognitive, affective and behavioural generalisation and adaptation across diverse environmental contexts. This article also discusses the importance of the cerebellum for understanding general factor development, given the early maturational timing of the cerebellum, and high sensitivity to early environmental influence. Finally, I propose a cerebellar role within the Hierarchical Taxonomy of Psychopathology (HiToP); an important framework for understanding of the latent transdiagnostic structure of psychopathology. If correct, consideration of the cerebellum can facilitate integration of psychometric and translational neuroscience perspectives to provide a broader and unified biopsychosocial understanding of psychological, and specifically mental health phenomena.
