I. COGNITIVE ABILITIES (h² ≈ 0.70–0.80)
───────────────────────────────────────────────────────────────
• General intelligence (g) ............... h² = 0.75–0.80
↳ Plomin et al., 2016; Bouchard & McGue, 2003; Deary et al., 2010
• Processing speed ....................... h² = 0.70–0.80
↳ Finkel et al., 2005 (Swedish Twin Registry); Luciano et al., 2004
• Working memory capacity ................ h² = 0.70–0.75
↳ Friedman et al., 2008; Ando et al., 2001
• Verbal ability .......................... h² ≈ 0.70
↳ Harlaar et al., 2005; Plomin & Kovas, 2005
• Spatial ability ......................... h² = 0.70–0.75
↳ Tosto et al., 2014; Vandenberg, 1969
• Mathematical ability .................... h² = 0.70
↳ Kovas et al., 2007; Haworth et al., 2009
───────────────────────────────────────────────────────────────
II. PERSONALITY, BEHAVIORAL, AND SOCIAL TRAITS (h² ≈ 0.40–0.70)
───────────────────────────────────────────────────────────────
• Risk-taking propensity .................. h² = 0.55–0.72
↳ Zuckerman, 1994; Linnér et al., 2019 (GWAS)
• Time preference / impulsivity ........... h² = 0.50–0.70
↳ Anokhin et al., 2011; Eisenberg et al., 2007
• Aggression (reactive) ................... h² = 0.50–0.70
↳ Miles & Carey, 1997 (meta-analysis)
• Religiosity (intrinsic) ................. h² = 0.40–0.70
↳ Koenig et al., 2005
(Note: higher heritability in secular societies)
• Political orientation (Left–Right) ...... h² = 0.40–0.65
↳ Alford et al., 2005; Hatemi et al., 2014
• Sexual orientation (male) ............... h² = 0.30–0.60
↳ Bailey et al., 2000; Sanders et al., 2017
• Addiction vulnerability ................. h² = 0.50–0.70
↳ Kendler et al., 2003; Vink et al., 2012
───────────────────────────────────────────────────────────────
III. PSYCHIATRIC & NEURODEVELOPMENTAL DISORDERS (h² ≈ 0.70–0.90)

↳ Sullivan et al., 2003
• Bipolar disorder liability .............. h² ≈ 0.80
↳ Smoller & Finn, 2003
• Autism spectrum disorder liability ...... h² = 0.70–0.90
↳ Tick et al., 2016; Colvert et al., 2015
• ADHD liability .......................... h² = 0.70–0.80
↳ Faraone et al., 2005
───────────────────────────────────────────────────────────────
IV. CATEGORY OVERVIEW (Summary)
───────────────────────────────────────────────────────────────
Cognitive Abilities ............. 0.70–0.80 → Strongly genetic
Behavioral / Social Traits ...... 0.40–0.70 → Moderately genetic
Psychiatric Disorders ........... 0.70–0.90 → Highly genetic
