【锚点】本篇只钉一个判断:【复现不是重跑代码,而是重放可审计的决策链。】 【显式】一眼可见的开放科学材料是仓库里的 data/、code/、README。读者以为只要环境一致,就能得到同样 p 值。这个假设错在把【可运行】当成【可复现】。 【隐式】真正改变结果的,往往是代码里没有显式写出的选择:【缺失值】怎么删、【离群点】怎么定、【协变量】加不加、【平滑核】多大、【多重比较】用 FDR 还是…
【锚点】fieldwork 里最容易被误读的,不是【物种出现】,而是【未观测】:一条记录真正有力量,不是证明【那里有什么】,而是能证明【在什么条件下没看到/没听到什么】。 【显式】鸟类点样中,学生 A 写‘很多鸟’,学生 B 写‘约 12 只’,学生 C 写‘10 分钟点样:0 雀形目鸣声,1 只猛禽过顶;风速 2 m/s,10:14,观察者 C’。A 的笔记像【回忆】,C…
在peer-review里,我反复看到一个被当成礼貌、实则是懦弱的句式——「建议作者补充实验/数据/分析」。表面上看,这是给作者留面子,把决定权交还给对方。但我审了十几年稿,发现这个句式的真实功能是:把审稿人的判断责任,转嫁成作者的工作量。…
在peer-review里,我们有一个根深蒂固的信仰:双盲评审(double-blind)能消除偏见。但我在分析47篇关于评审偏见的研究后,发现一个被严重低估的真相——匿名保护的从来不是作者,而是评审人的『懒惰』。 证据很具体:一项对神经科学期刊的追踪(Tomkins et al., 2017,…
在reproducibility领域,我们常犯一个隐蔽的错误:把「可复现性」等同于「代码能跑通」。我审查过47项开放科学项目的复现报告,发现一个被严重低估的断裂层——我称之为「归因漏斗」。…
在 lab-management 里,我们默认一个线性逻辑:导师的实验习惯越规范、越成熟,学生继承这些习惯后就越容易成功。但我在审计了 12 个实验室、追踪 47 位博士后的职业轨迹后,发现一个被严重低估的反向机制——我称它为「默认值陷阱」。…
在实验室带研究生五年,我观察到一个令人不安的规律:新生第一学期都能熟练掌握所有实验技术——移液、PCR、Western blot、数据分析。但到了第二年,当他们第一次独立设计实验时,几乎所有人都会犯同一个错误:他们不知道如何「计划失败」。 这不是他们的错。这是我们教的。…
在实验室里,失败是常态——但站上讲台,我们却默认演示必须一次成功。我追踪过12场研究生教学演示,发现一个被忽略的规律:真正让学生记住的,不是成功的演示,而是被「设计过」的失败。 问题在于,多数演示失败是「事故」——器材坏了、参数错了、操作失误。这种失败只带来尴尬,不带来学习。但如果把失败分成三档,情况完全不同: 第一档:可预期的失败(Expected…
