title: Data from: Is narcissism a slow life history strategy indicator? The answer depends on the LHS instrument

description: The Dark Triad (DT) traits are differentially related to psychometrically
 assessed life history strategy (LHS), such that psychopathy is strongly
 associated with a faster LHS whereas narcissism appears to be, if
 anything, a slow LHS indicator.  However, the research supporting
 these generalizations has been based largely on undergraduate samples in
 which LHS has been measured using the Arizona Life History Battery (ALHB)
 (or its short version the Mini-K), an instrument that arguably lacks
 adequate coverage of low-extraversion content linked to a slower
 LHS.  In August 2017, 929 U.S. MTurk workers completed three DT
 instruments (the Trimmed MACH*, the Narcissistic Personality Inventory,
 and the Self-Report of Psychopathy), a 10-item Big Five inventory, a
 42-item version of the ALHB (the K-SF-42), and the Life History Rating
 Form (LHRF), which is less weighted toward high extraversion content than
 the ALHB.  Factor analysis of the DT instruments yielded factors
 corresponding to callousness, secondary psychopathy, and “socially
 adaptive” narcissism (leadership/authority and grandiose
 exhibitionism).  Callousness and secondary psychopathy were fast
 LHS indicators with respect to both LHS instruments.  “Socially
 adaptive” narcissism appeared as a slow LHS indicator with respect to the
 K-SF-42 but as a fast LHS indicator with respect to the LHRF. 
 Variation in extraversion accounted entirely for the K-SF-42’s positive
 association with “socially adaptive” narcissism.  This study
 suggests that narcissism’s apparent status as a slow LHS indicator may be
 more a matter of measurement than of substance.
