「报错最多的实验室最安全,报零错的实验室最危险」:心理安全把错误率指标整个反转了

【锚点】这一篇只钉一个判断:【实验室里「错误率」不是安全指标,是「报告倾向」指标——一个季度报零错的组,多半不是没出错,是没人敢报;把错误率当 KPI 去压低,你压低的不是错误,是报告。】 【显式】三条可查的事实: 1. Amy Edmondson 在护理团队的研究(1996, JABS;并延伸到 1999, ASQ 的心理安全框架)里发现:绩效评级更高的护理单元,报告的用药错误反而更多。 2.…

「实验室的错误日志,测的是『敢不敢报』,不是『错没错』」

【锚点】这一篇只钉一个判断:【一个实验室上报的错误数,首先是一条关于『心理安全感』的测量,其次才是一条关于『错误率』的测量。把错误日志当质量指标,会奖励沉默,而不是奖励安全。】 【显式】先给反直觉的证据。Edmondson 1996…

「零错误报告」的实验室最危险——心理安全感不是让人舒服,是让人敢说

【锚点】这一篇只钉一个判断:【实验室里「报告的错误数」不是质量指标,是安全指标——它上升,往往说明团队在变好。】 【显式】先给数字。Edmondson 在 1996 年研究了 8 个医院护理单元,1999 年又追踪了 51 个制造团队。她原本预期:心理安全感高的团队,错误更少。结果相反——高绩效的护理单元报告的用药错误更多。…

实验室里最便宜的风控:10 分钟「事前验尸」

【锚点】实验室管理最常被低估的,不是【事故复盘】,而是【可学习失败】。 【显式】很多组会把 SOP 贴满墙,但学生真正卡住的,常常不是步骤,而是【为什么这一步在这里】。 【隐式】导师以为【给方向】就是培养判断力;其实学生更需要的是【可检查的失败假设】。 【细微】事前验尸(pre-mortem)不是悲观,而是把隐性判断提前变成显性检查点。Gary Klein 在 1998…

「高绩效实验室报告的差错更多」:错误报告率是学习指标,不是质量指标

【锚点】这一篇只钉一件事:把【差错报告率】当成质量指标,会系统性地惩罚最会学习的实验室。因为报告率 = 【真实错误率】×【报告倾向】,而这两个因子在好团队里往往反向变动——指标一聚合,排名就翻转。 【显式】Amy Edmondson 1999 年在 Administrative Science Quarterly 发表的心理安全感研究,第二部分是 8…

「报告更多用药错误的病区更安全」:一条能把 lab 排名整个翻转的观测方程

【锚点】这一篇只钉一个判断:【你在 lab 里数到的错误率,不是错误率,是「错误率 × 报告概率」;当报告概率随团队变化时,按观测错误率排名,会把最安全的组排到最后。】 【显式】Edmondson(1999,Administrative Science Quarterly 44:350–383,"Psychological Safety and Learning Behavior in Work…

「报告事故最少的实验室,往往是最危险的」:安全指标测的是报告意愿,不是安全

【锚点】这一篇只钉一个判断:实验室的「可记录事故率」不是【安全】的度量,是【报告意愿】的度量。两个实验室事故率相差十倍,更可能说明心理安全感相差十倍,而不是危险程度相差十倍。 【显式】Amy Edmondson 1999 年在《Administrative Science Quarterly》发表的对 51…

「零事故」的实验室最危险:报告率是安全传感器,事故计数不是

【锚点:事故报告数是「愿意开口的人数」的函数,不是「出错次数」的函数。拿报告数当安全指标,等于拿体温计的读数当体温。】 【显式】Edmondson 1996(Journal of Applied Behavioral Science 32(1):5–28)在两家医院的 8…
