风险、不确定性与认知偏差

区分风险（结果概率已知的决策）与不确定性（结果未知的决策）；识别扭曲风险评估的认知偏差：可得性启发（根据例子容易想到的程度来判断可能性）、现时偏差（把眼前利益看得过重而忽视长远后果）、乐观偏差（低估自己面临的风险）和群体思维；理解青少年大脑在生物学上为何倾向于更高的风险承受水平；运用结构化的决策框架处理真实选择；理解在仅凭事实无法确定答案的决策中，个人价值观所起的作用。

Distinguish between risk (decisions with known probabilities) and uncertainty (decisions with unknown outcomes); identify cognitive biases that distort risk assessment: availability heuristic (judging likelihood by how easily examples come to mind), present bias (overvaluing the immediate over the future), optimism bias (underestimating personal risk), and groupthink; understand why adolescent brains are biologically calibrated toward higher risk tolerance; apply a structured decision-making framework to real choices; understand the role of personal values in decisions where facts alone cannot determine the answer

{{name}}能否解释为什么冒险并不总是非理性的，并描述一种导致人们在日常决策中误判风险的认知偏差，例如为什么青少年往往容易低估某些危险？

Can {{name}} explain why taking a risk isn't always irrational — and describe one cognitive bias that causes people to misjudge risk in their everyday decisions, such as why teenagers tend to underestimate certain dangers?
