Harden's 4-million-person study found that a single suite of genetic variants predisposes people across a range of what look like unrelated rule-violating behaviors: ADHD symptoms, early sexual activity, more partners, cannabis use, problematic alcohol, smoking, and self-described risk-taking. She reframes these not as separate moral failures but as expressions of one underlying dimension — disinhibition — doing things that invite social judgment or consequences anyway.
