“…Within certain bounds, they adaptively respond to cues from the present living environments and regulate behavior accordingly. Grouped together as environmental adversities, harshness and unpredictability are indicated by such proxies as change of employment or residence (e.g., Simpson, Griskevicius, Kuo, Sung, & Collins, 2012 ; Zuo, Huang, Cai, & Wang, 2018 ), dangerous neighborhoods (e.g., Hampson, Andrews, Barckley, Gerrard, & Gibbons, 2016 ), chaos in the home (e.g., Del Giudice, Hinnant, Ellis, & El‐Sheikh, 2012 ), negative life events (e.g., Simpson et al., 2012 ), and low family income or socioeconomic status, income change, and income to needs ratio (e.g., Belsky, Schlomer, & Ellis, 2012 ; Doom, Vanzomeren‐Dohm, & Simpson, 2016 ; Szepsenwol, Shai, Zamir, & Simpson, 2021 ). Consistent with LH predictions, these proxies of environmental adversities are correlated with fast LH strategies (e.g., Brumbach, Figueredo, & Ellis, 2009 ; Chen, Shi, & Sun, 2017 ; Stamos, McLaughlin, Bruyneel, & Dewitte, 2021 ) and fast LH traits such as aggression (e.g., Doom et al., 2016 ; Ellis, Shakiba, Adkins, & Lester, 2021 ; Simpson et al., 2012 ).…”
