Harari developed Sapiens from a university course that attempted to summarize all of history for first-year students. Rather than completing research and writing in isolated phases, he tested ideas repeatedly on the class. Boredom indicated that something needed to change; frequent questions suggested a topic deserved expansion; confusion prompted a better example or explanation. The method treats novice response as a diagnostic instrument rather than a popularity contest. Its strongest assumption is that, in accessible fields such as history, a capable beginner should understand a well-formed explanation. If beginners consistently cannot follow it, the author may not understand the idea sufficiently or may be presenting it in the wrong way.
Origin
Harari developed Sapiens through several years of teaching a broad history course at the Hebrew University and revising ideas in response to first-year students.
Core principles
- 01Novice confusion reveals weaknesses experts may overlook.
- 02Boredom signals that an idea or presentation needs revision.
- 03Repeated questions reveal subjects that deserve more attention.
- 04Difficulty explaining an idea may indicate incomplete understanding.
- 05Writing and research can improve through continuous interaction.
How to run it
- 1
Choose a novice audience
Select intelligent participants who lack specialist familiarity with the subject but possess enough background to engage with it.
Pro tip Use several people so one individual's preferences do not dominate.
Watch out Do not mistake missing prerequisites for a failure of explanation.
- 2
Present an early version
Teach, speak, or share a draft before it feels finished so feedback can still influence its structure.
Pro tip Test one coherent section at a time.
Watch out Waiting for polish makes major revision psychologically harder.
- 3
Observe diagnostic reactions
Record where attention fades, questions cluster, or participants cannot explain the point back accurately.
Pro tip Prioritize repeated patterns over isolated comments.
Watch out Verbal praise alone provides little diagnostic information.
- 4
Diagnose the cause
Decide whether each problem reflects a weak idea, insufficient understanding, poor sequencing, or a missing example.
Pro tip Try explaining the disputed point aloud without jargon.
Watch out Do not automatically blame the audience.
- 5
Revise and retest
Change the explanation, examples, emphasis, or underlying argument and expose the new version to another feedback cycle.
Pro tip Keep a record of which revisions improve comprehension.
Watch out Do not optimize solely for entertainment at the expense of accuracy.
In the wild
Harari taught a course summarizing human history for several years. He used boredom, questions, and confusion from first-year students to decide what to change, expand, or explain with a new example before turning the material into Sapiens.
→ A broad historical argument became clearer, more engaging, and suitable for an international readership.
A strategist gives an early memo to colleagues outside the project and asks them to restate its recommendation. When they understand the evidence but misidentify the decision, she rewrites the opening, adds a concrete example, and tests it with another group.
→ Decision-makers understand both the argument and the action it requires.
Common mistakes
Treating every reaction as a command
Feedback supplies evidence about a problem, but the author must still diagnose and choose the solution.
Testing only with experts
Experts can silently fill gaps from their own knowledge and conceal weaknesses that ordinary readers will encounter.
Defending confusion
Assuming the audience is at fault prevents the test from improving either the idea or its explanation.
Is it for you?
Best for
It is best for writers, teachers, researchers, and presenters explaining complex but accessible subjects.
Not ideal for
It is not ideal for material that genuinely requires extensive technical prerequisites before it can be understood.
From the transcript
“I had the opportunity to test all kinds of ideas on the students and see the reaction.”
“If something is unclear, I should find an example or some other way of explaining this difficult point.”
“It was very interactive and then fluid and changing all the time.”
