Summary of the Key Points
This article criticizes the current education system for its over-reliance on exams, grades, and standard answers, pointing out that this leads to a lack of "cognitive compounding" (the ability to apply knowledge flexibly), practical feedback skills, the development of multiple talents, and a sense of long-term collaboration among students. It argues that the core mission of education should be to help people build a "map for surviving in the real world"—one that enables them to correct their judgments, resist misinformation, and accumulate credibility over time. The article also emphasizes that AI should not be used merely as a tool for efficient question-solving but rather as a "talent radar" and a generator of real-world tasks to help individuals find dynamic paths for growth.
1. Why do some learn faster while others only memorize more?
Today's education gives us the illusion that learning is like putting coins into a piggy bank; memorizing words or practicing large numbers of problems will yield "returns" in the form of good grades, but this is a case of linear addition—the knowledge becomes obsolete once the exam is over. True learning involves compound growth: understanding fundamental concepts (such as the "marginal effect" in economics) can help you understand business and life issues more quickly, much like a tree trunk sprouting new branches rather than just isolated leaves (fragmented knowledge points).
For example, Charlie Munger's concept of a "thought lattice"—by connecting interdisciplinary principles such as mathematical probability, biological natural selection, and psychological reward mechanisms—you create a framework for understanding the world. However, many people only memorize the individual parts (formulas, templates), without a solid foundation; they struggle when the context changes or additional conditions are missing in real life.
The Feynman learning method—explaining complex concepts in simple language—is not just a technique for communication but also a tool to assess understanding. Unfortunately, our language education has turned this into rote memorization, failing to teach the thinking process that can be applied in engineering and business.
2. Does stopping learning after graduation mean being lazy?
Many people stop learning after leaving school, but it's not because they're lazy. During their student years, exams force them to learn; once they start working, they need to understand the rules of the job. However, once they settle into a stable situation, old methods are sufficient for their tasks, and the outside world no longer pushes them to update their knowledge. As a result, some people repeat the same experiences for years, using what was learned in the first year over and over again.
Some might ask, "Aren't academic experts and business elites constantly learning?" The problem is that modern society rewards narrow skills: someone who excels at writing papers in a lab may not understand business strategies, and someone who is good at making money may not grasp macroeconomic cycles. A healthy mindset should be T-shaped, with depth in a specific area and the ability to apply knowledge across different fields. Don't mistake proficiency in one area for a comprehensive understanding of the world; otherwise, you risk overstepping your bounds (for example, a doctor giving investment advice).
3. What do grades tell us?
Grades are useful, but they have a flaw: they only measure whether you meet the expectations of the examiners, not whether you truly understand the subject. For instance, you might get a high score by guessing the examiner's intentions, but in reality, problems are not always structured according to a fixed syllabus; there may be no standard answers, missing conditions, or the questions themselves can be ambiguous.
Worse still, grades have replaced the true goals of education:
- Fundamental concepts are replaced by fragmented knowledge points.
- The ability to apply knowledge is reduced to memorizing fixed question formats.
- Practical feedback is replaced by grade rankings.
Those who only focus on grades for a long time become accustomed to the idea that hard work equals guaranteed rewards, but in reality, things don't always follow a set pattern, and there are no "standard answers" to provide security.
Another hidden issue is that grades suppress our diverse talents. Humans have multiple talents (some are sensitive to colors, others are good at organizing), but grades force everyone into a uniform framework. Improving from 80 to 95% may indicate skill improvement, but going from 95 to 100% often involves eliminating minor mistakes, which requires significant effort with little cognitive gain and can even stifle curiosity and creativity.
4. The "map" education should provide: not standard answers, but these three abilities
Education should help people build a "map for surviving in the real world," which includes at least three key abilities:
1. Adjusting your actions based on consequences: Instead of being overwhelmed by society, learn from mistakes within safe boundaries—perhaps a project fails because users don't like it, or code doesn't work, or an event fails to attract participants. This kind of feedback is painful but teaches you to adjust your judgments independently of standard answers.
2. Resisting the flood of information: Critical thinking is like antivirus software for the brain. When encountering persuasive arguments or promises of easy profits, ask yourself: What are the evidence? Why is this being told to me? Are any facts omitted? Even the smartest people can be misled by pseudoscience and consumer traps.
3. Accumulating long-term credibility: In the short term, selfishness and dishonesty might seem advantageous, but in the long run, reliability and integrity become invisible assets that attract cooperation and opportunities. Those who overdraw on trust become isolated.
5. What should AI do for children? Not just grade-checking, but act as a "talent radar"
AI should not be used to monitor homework completion; instead, it can help education in the following four ways:
1. Talent radar: Identify children's strengths through real-world tasks (such as crafting or writing scripts)—do they have a good sense of space or are they organized?
2. Real-world task generator: Make learning about doing projects, creating works, and collaborating, rather than simply practicing problems. For example, learning physics should involve building a small rocket.
3. Feedback calibrator: Provide more than just "right/wrong" feedback; explain where your understanding is lacking—for instance, when grading a essay, say "your argument lacks evidence."
4. Life map: Connect your interests, abilities, and real-world opportunities, rather than labeling you with fixed roles (doctor, teacher, etc.).
The value of AI is not to speed up the old system (like grading homework faster) but to provide each person with a dynamic, multi-dimensional path for growth. Instead of asking "where do you rank?" ask "in which areas do you learn the fastest? Which talents are being overlooked?"
Conclusion: The essence of education is to "understand the real world"
Education should not reduce people to mere numbers but help them:
- Develop knowledge into a structured framework (cognitive compounding).
- Calibrate their judgments based on practical feedback.
- Discover their unique talents.
- Learn to collaborate effectively over the long term.
A child shouldn't be judged solely by grades; education should enable them to develop abilities that cannot be measured by exams and provide opportunities to apply those abilities in the real world. This is what education should aim to achieve.
