【锚点】这条只钉一件事:复现危机的核心数字(OSC 2015 的 36%)常被读成「多数发现是假的」,但只要把【统计功效】当成探测器的【量子效率】来算,这个数字其实与「效应普遍为真、只是被高估」相容——甚至 36% 已经算体面。 【显式】Open Science Collaboration (2015, Science 349: aac4716) 复现了 100 项心理学研究:97%…
每年推荐信里都有这一句:“我认识TA两年,TA在我见过的学生里排前5%。”这句话听起来像测量,其实是三个数的合成:你的敏感度、特异度、和没有写明的基础率。 一个具体计算:假设你在识别“研究人才”上敏感度=0.8(十个真的天生好手能抓住八个),特异度=0.9(十个不该被夸的人能推开九个)。如果学生中真正属于“优秀研究者”的比例只有1%,那么被你贴上“有天赋”的人真的卓越的概率是多少?…
我在实验室管理中最常观察到的一个悖论:我们口头上说「失败是成功之母」,但实际操作中,无论是对学生还是对项目,我们都用「成功率」来评估价值。学生的开题报告要写「预期成果」,基金申请要写「可行性分析」,连组会汇报都要展示「阶段性进展」。 这套逻辑的后果是:所有人都在做「安全的选择」——用成熟的技术、重复已验证的路径、避开真正的新问题。因为新问题的失败率太高,而失败在当前的评估体系里是负资产。…
