大学里我最喜欢的一位教授承认自己是个骗子
One of my favorite professors in college was a self-confessed liar
2009 — 2022，它一次次回到首页
黑点是上首页（≥ 50 分）的那次投稿，空心点是没冲上去的投稿，点越大分数越高。
导读
作者回忆大学里一位自称“骗子”的教授：他在讲课中故意埋入谎言，让学生保持怀疑、主动验证，而不是被动接受知识。这种教学方式让作者印象深刻，也引发了对批判性思维培养的讨论。
为什么经久不衰：它用一个生动的故事说明被动听讲与主动怀疑的差别，跨越十几年仍能引发教育者与职场人的共鸣。

质疑这种手法规模化后是否仍有效
太精彩了。这种方法能否在更大范围应用？还是说一旦失去新鲜感，对学生就不再有效了？

Excellent, excellent. Could this be applied on a wider scale, or would the loss of novelty dull the effect on students?
重点在于启发思考的教学设计，而非谎言本身
这个故事的核心其实不是撒谎，而是教授跳出固定课程、思考如何让学生真正学会思考。我自己的例子：一门文学课在14周阅读讨论之后，期末考试竟是一场品酒考试——把学到的分析技能迁移到全新领域。

The defining characteristic of this story is not the lying part, but professors who deviate from strict curriculum and think about how best to make their students think. My particular canonical example - Literature and Criticism Seminar (An English course) - after 14 weeks of reading passages of poetry and prose and discussing them in class, our final exam was a wine-tasting exam. An opportunity to take the skills we had learned and apply them to a different domain, and have some fun. The class was very small (8 people) so it was easy for the professor to do this and not have to worry about evaluation issues.
分享类似经历，并调侃这招可能被用来掩饰真实失误
听起来是位好老师。我遇到过一位更“恶劣”的教授：他不定期地在讲课中掺入错误，被质疑就承认，没人发现就让大家继续无知下去。那是流体力学课，错误常能通过仔细检查推导的代数过程找出来。我怀疑这招只是为了掩盖他偶尔真的会犯错。

Sounds like a great teacher. I had a prof who was a bit more sadistic/incompetent about this. He would incorporate a falsehood into his lectures, not always and not always just one. When challenged he would admit it but if no one caught the mistake he would let us live on in ignorance. This was a fluid dynamics course so you could frequently find the "lie" by carefully going over the algebra in his derivations. I'm pretty sure this was just a clever ploy to conceal the fact that once in a while he did, in fact, make mistakes.
把“埋错误测审查”迁移到代码评审场景
我有太多同事对我的 pull request 只是走过场盖章通过。我很想在每次提交里故意放一个明显的错误，看看谁在认真看。可惜我自己也误放过太多次而无人察觉。也许可以把它游戏化、记个分。

I have too many colleagues who rubber-stamp my pull requests. I'm tempted to include a significant mistake in each one to see who's paying attention. Unfortunately I have done so too many times by mistake with nobody noticing. Maybe if we gamify it a bit and start keeping score. I don't have authority to make a bonus contingent on the result, but it could be money well spent.
补充类似案例：用故障计算器检验学生的常识判断
我听过类似的故事：有些数学考试中老师故意发“有故障”的计算器，结果不是 1+1=3 那种明显错误，而是 22/7=3 这种，看哪些学生盲信屏幕结果，哪些能用逻辑和常识判断结果不对。

Nice one! I heard/read a similar story where in some math exams the teachers provided “faulty” calculators to all students in order to see which students relied to the result of the calculator screen and which of them used their logic and common knowledge to understand when a result is wrong. The calculators didn’t produce errors obvious like 1+1=3 but more like 22/7=3. Nice tactic and highly educational lesson :-)
提醒该手法可能适得其反，但不确定
这个点子整体很有趣，但我要对那节“其实没撒谎”的课保持谨慎。作者本人接受良好，但对其他学生来说，这可能显得像廉价把戏，反而削弱他们今后找谎言的动力。这种课来一次可以，来多了恐怕不行。不过话说回来，我记得有说法认为不稳定的奖励比稳定的奖励激励效果更强，也许未必？

The overall idea seems quite fun, but I'd be cautious about the lecture where he doesn't actually lie. Although the author seems to have taken it quite well, it could easily have come off as a cheap trick to other students and reduced motivation to find future lies. One of those kinds of lectures might work, but much more might not. Although on the other hand I do remember hearing something along the lines of inconsistent rewards having a stronger incentive effect than consistent rewards, so maybe not?
