“…In related research, drawing on these data, we found satisfactory levels of measurement invariance, allowing us to make reliable cross‐cultural comparisons (Rogoza et al, 2020), and our isomorphism tests support this conclusion. The Dirty Dozen measure of narcissism, for example, may capture better vulnerable than grandiose narcissism, but the current results are consistent with work using other measures of narcissism (Jonason et al., 2019; Schmitt, Alcalay, et al., 2017). Above measurement concerns, there are doubts about whether Machiavellianism is redundant to psychopathy (Miller, Hyatt, Maples‐Keller, Carter, & Lynam, 2017; see also: Vize, Collison, Miller, & Lynam, 2018; Vize, Lynam, Collison, & Miller, 2018).…”
