A test of the differentiation of personality by intelligence hypothesis using the Big Five personality factors

Using the 16PF to Test the Differentiation of Personality by Intelligence Hypothesis

“…Austin et al (2000) stated that the differentiation of personality by intelligence hypothesis reflects the finding that, "the more able are more variable on the trait dimension" (p. 407). Recently, Schermer et al (2020) demonstrated that individuals higher in intelligence responded to a Big Five personality scale more consistently (higher internal reliability values), had larger standard deviations, and greater scale variances, supporting the suggestion by Austin et al (2000;see also Navarro-González et al 2018). One method that could be utilized in future studies testing the differentiation hypothesis could be to ask individuals to think aloud while completing personality items.…”

The differentiation of personality by intelligence hypothesis in a sample of British managers

“…Similarly, Navarro-González et al (2018) demonstrated that "person reliability" is positively related to general mental ability. Recently Schermer et al (2020a) also provided some support for the suggestion that those higher in intelligence would also have higher scale reliability values.…”

“…The tests of variance found greater variability in scale scores for the higher ability group for many of the facet scores of the Big Five dimensions, with the exception of agreeableness, which demonstrated a reverse pattern. Why agreeableness was in the opposite direction is an area requiring further research as both Schermer et al (2020a) and Harris et al (2006) reported greater variability in agreeableness scores in higher ability groups. Possibly the difference could be due to the assessment centre condition of the managers assessed in the present study as De Fruyt et al (2006) demonstrated that agreeableness did not show a significant increase in variance for a higher intelligence scoring group and that the structure of the Big Five remained consistent across intelligence levels in a selection context.…”

“…Harris et al (2006) found that there was greater personality variability for a higher intelligence group but only for adults and not late adolescent students. Schermer et al (2020a) recently reported greater variability and scale ranges in a higher ability tertile compared to a lower ability tertile in a sample of students. De Fruyt et al (2006) reported that openness, neuroticism, and extraversion were more variable for those higher in intelligence, but that the latter two only showed greater variability at higher intelligence scores (greater than an IQ of 115).…”

Individual psychological distance: a leadership task to assess and cope with invisible change

“…Later, many researchers extended the historical notion including Goldberg (1981); McCrae and Costa (1987); Norman (1967); Smith (1967) known as the "big five" factors model. The quest is ongoing among researchers, yet a unique or exact label of these dimensions remains to be decided even concluding a variety of positive outcomes in different situations and individual differences (Paunonen, 2003;Schermer et al, 2020). The research about big-five has no time, gender, society or continental limitations in the literature.…”
