The tonality varies from critical to curious, shaping the overall sentiment of mixed receptions.

ImpactModerate impact

While several users acknowledge the study's importance, others view its impact as limited, often framing it as just another piece of conflicting information.

Abstract in brief

  • Exogenous testosterone was found to increase sensitivity to moral norms when making moral dilemma judgments, leading to more inaction in situations where harmful actions could benefit the greater good.
  • Using a mathematical model, the study differentiated between sensitivity to consequences, moral norms, and preferences for action, concluding that testosterone heightened the sensitivity to moral norms.
  • In contrast, higher levels of endogenous testosterone were linked to lower sensitivity to moral norms, suggesting a complex relationship between testosterone and moral decision-making that challenges previous assumptions.

A perplexing set of findings: Exogenous testosterone increases sensitivity to moral norms in moral dilemma judgements, whereas endogenous testosterone (analyzed across individuals) is associated with a decrease in sensitivity. Via ⁦@NatureHumBehav⁩ https://t.co/xVYWrAwybD

@PunishedLink https://t.co/3P1IKEvVC2 This is just a youtube channel by not-a-doctor, but through his research it appears that testosterone doesn't make men more violent, it makes men maintain a status quo, and if violence is a part of that then perhaps yes.
