Explain testosteron to me

Testosterone is a hormone that can turn up existing tendencies and influence how people pursue or defend status; it doesn’t simply create aggression. 1

• 1. Prominent traits: Testosterone can amplify behaviors already present, including libido and aggression. 1
• 2. Challenge hypothesis: Testosterone may rise when status is challenged, making behaviors that help maintain status more likely. 2
• 3. Context matters: The behavior that earns status varies by setting. Testosterone may amplify aggression where aggression is rewarded, or generosity and trustworthiness where those bring status. 3
• 4. Confidence and judgment: Testosterone can increase confidence, but sometimes that confidence becomes overconfidence: people may cooperate less, make impulsive decisions, and misjudge risks. 4
