A fundamental assumption about human behavior may need revision. The widely-held belief that testosterone drives risk-taking—from financial decisions to dangerous behaviors—appears to lack scientific foundation when examined across the full spectrum of research. This finding has implications for everything from understanding gender differences in investment strategies to designing behavioral interventions.
Analyzing 52 studies encompassing 17,340 participants, researchers found essentially zero correlation between testosterone levels and risk preferences across diverse experimental paradigms. The aggregated effect size was statistically indistinguishable from zero, with publication bias analyses confirming this wasn't due to selective reporting of negative results. Interestingly, only lottery-based economic tasks showed even a modest positive association, while other established risk measures—including the Balloon Analogue Risk Task, Iowa Gambling Task, and self-reported risk preferences—demonstrated no relationship whatsoever.
This challenges decades of research linking androgens to behavioral risk patterns and suggests the testosterone-risk narrative may be more cultural assumption than biological reality. The meta-analysis also found no sex differences in testosterone-risk correlations, contradicting theories that hormonal influences on risk-taking are stronger in males. These results point toward a more nuanced biopsychosocial model where risk preferences emerge from complex interactions between cognitive processes, situational contexts, and task-specific demands rather than simple hormonal drivers. For health-conscious adults, this suggests that understanding personal risk tolerance—whether in health decisions or lifestyle choices—requires looking beyond biological markers to encompass psychological and environmental factors.
