The Dark Factor of Personality (2024)

Moshagen, M., Hilbig, B. E., & Zettler, I. (2018). The dark core of personality. Psychological Review, 125, 656-688.(doi)(download copy (PDF))

Original publication spelling out the theoretical idea and definition of D and demonstrating that (i) many dark traits are (largely) subsumed by D, (ii) D accounts for diverse aversive (behavioral) outcomes, whereas the specific dark traits provide little to no additional explanation of these outcomes (beyond D), (iii) D can be fully represented by subsets of indicators in line with its fluid nature (i.e. D can be measured by any combination of dark trait indicators), and (iv) within models of basic personality structure, D is located across multiple dimensions (especially Honesty-Humility, Agreeableness, and Conscientiousness).

Theoretically specifies and empirically tests the role of beliefs and justifications as per the definition of D, showing (i) that D involves higher subjective justifiability of those aversive behaviors that individuals high in D are more likely to engage in, (ii) that D uniquely relates to diverse descriptive and injunctive beliefs – related to distrust (e.g. cynicism), hierarchy (e.g. authoritarianism), and relativism (e.g. normlessness) – that serve to justify aversive behavior, and (iii) a theoretically derived pattern of moderations and mediations supporting the view that D accounts for aversive behavior because it fosters subjective justifiability thereof – at least in part due to certain beliefs and the justifications they afford.

Based on rational item selection techniques and data from seven large and highly heterogeneous samples (total N > 165,000), item sets (comprising 70, 35, and 16 items, respectively) suited for an economic and psychometrically superior direct assessment of D are identified. For more on measuring D and all item translations, see Measuring D below.

Further investigates the internal structure of the D70 item set to measure D based on three large and heterogeneous samples. Shows that a bifactor structure modeling D along with five specific factors — or themes — labeled Callousness, Deceitfulness, Narcissistic Entitlement, Sadism, and Vindictiveness, yields a superior measurement model for D.

Tests the theoretical notion that D is the underlying tendency from which specific dark traits arise as flavored manifestations. Shows in 4-year longitudinal data that D is stable and indeed more so than specific dark traits and that D longitudinally accounts for (change in) dark traits, sometimes more so than the dark traits themselves. For example, D (modeled without any spitefulness items!) is a descriptively better predictor of spitefulness four years later than spitefulness itself.

Investigates the structure of the D Factor of Personality across age and gender using Local Structural Equation Modeling. Shows that the structure of D is highly stable across both age and gender, thereby supporting the conceptualization of the D factor. Further, men exhibited higher levels on D than females, and the level on D decreases as age increases.

Specifies the theoretical and conceptual differences between the common core of dark traits, the D factor, and HEXACO Honesty-Humility. Demonstrates across four studies and several criteria (pretentiousness, distrust-related beliefs, and empathy) that D and low Honesty-Humility are best understood as functionally different and nomologically distinct constructs.

Tests and rejects the notion that the common core of dark traits, the D factor, is essentially equivalent to the low pole of (Big Five) Agreeableness. Shows that D and Agreeableness are functionally distinct, that is, account for different variance components in theoretically relevant criteria, especially dishonest behavior, justifying beliefs, and (lack of) empathy and guilt.

Demonstrates the conceptual and empirical overlap between D and socially aversive tendencies as studied in abnormal psychology: narcissistic, antisocial, paranoid and borderline psychopathology. Shows that – despite the limited theoretical and operational correspondence between specific dark traits and instances of psychopathology – D is well suited as a common cause explanation and outpredicts not only the full range of basic personality dimensions (including those most strongly related to D: Honesty-Humility, Agreeableness, and Conscientiousness) in accounting for aversive psychopathology, but actually the same instances of psychopathology themselves.

Compares the broad dispositions D, HEXACO Honesty-Humility, and Big Five Agreeableness in term of how (well) they accound for antagonistic psychopathology. Shows that only D sufficiently and similarly covers all aspects of antagonistic traits (affect, behavior, and cognition) and thus affords a more balanced representation of antagonistic psychopathology.
