“…Although recent work criticizes the validity of applying LHT to trait variation within humans (e.g., Nettle and Frankenhuis, 2019;Zietsch and Sidari, 2019), this predictive lens has been useful for studying psychosocial developmental plasticity within underprivileged environments (see Kuzawa and Bragg, 2012). Relative to a slow life history strategy, people with faster life history strategies prefer immediate over delayed rewards (Griskevicius et al, 2011), reproduce earlier (Boothroyd et al, 2013;Hehman and Salmon, 2019), have more casual sex (Dunkel et al, 2015;Salmon et al, 2016), experience earlier sexual debut and report greater sexual risk-taking (James et al, 2012), pursue social status via dominance rather than prestige (Lukaszewski, 2015), score higher on measures of psychopathy (e.g., boldness, aggression, and disinhibition; Mededović, 2018) and dark personality (i.e., impulsivity, antisociality, entitlement/exploitativeness, Machiavellianism, and aggression;McDonald et al, 2012), and are more likely to use psychoactive substances (Richardson et al, 2014). These traits are advantageous in harsh, unpredictable environments to the extent that they help an individual to competitively capitalize on limited resources.…”
