Before you trust an insight your circle praises, name one effect a stranger could see and one person who gains nothing from your believing it.

Steps

1. Write the insight in one plain sentence, and write who is currently confirming it: teacher, group, feeling, or all three.
2. Name one observable change a stranger could notice over the next few weeks: less reactivity, a kept promise, a repaired relationship, a harm stopped.
3. Name one witness who gains nothing if you are right: a plain friend, someone you have wronged, a clinician, a record of your own behavior, or a person from a different path.
4. If you cannot name both the observable change and the non-gaining witness, hold the claim as something interesting, not as something true. Do not build identity or a major decision on it yet.
5. Do one small ordinary act that the insight should make easier today, and let the witness, not the group, tell you in a week whether it held.

Source Basis

• Run mode: Critique. Active frontier: The collective brain of awakening. Lineage exchange among cultural evolution, modern human-condition pressure, Neoplatonic ascent, and Advaita witness inquiry. The run weakens the frontier's premise that contemplative insight has no cheap external test.
• Primary-text comparison: Kalama Sutta, Anguttara Nikaya 3.65 (SuttaCentral), where the Buddha tells the Kalamas not to accept a teaching by tradition, lineage, scripture, logic, inference, or because a teacher is respected, but to test whether the qualities, when taken up, lead to harm or to welfare. Read against Henrich's success-biased and prestige-biased transmission in The Secret of Our Success, where copying the respected and the successful is exactly what makes the collective brain work. The comparison reveals that early Buddhism already distrusted the collective brain's normal selection rule for this domain and tried to install a conduct-and-harm filter instead.
• Cultural-evolution cards: cultural-evolution-innovation-in-the-collective-brain (recombination plus selection); cultural-evolution-the-secret-of-our-success (payoff and prestige bias); cultural-evolution-demography-and-cultural-evolution; cultural-evolution-population-size-does-not-explain-past-changes-in-cultural-complexity (Tasmania treated as contested). Confucianism: Innovation in the Collective Brain Confucianism: Population Size Does Not Explain Past Changes in Cultural Complexity Confucianism: The Secret of Our Success Manichaeism: Demography and Cultural Evolution
• Thinking-method source: the Kalama Sutta's rule of testing by lived consequence rather than by prestige was used as a reasoning lens. Critique of the method: a conduct test is itself confounded by expectancy, demand effects, and community reward, so it was paired with cultural evolution's requirement that the selection filter be independent of the variant's source.
• Modern human-condition: modern-human-condition-surgeon-general-social-connection-advisory (belonging and isolation), modern-human-condition-youth-mental-health-social-media-advisory (prestige, visibility, comparison), modern-human-condition-pew-where-americans-find-meaning-in-life. Modern Human Condition: Our Epidemic of Loneliness and Isolation Modern Human Condition: Social Media and Youth Mental Health Modern Human Condition: Where Americans Find Meaning in Life
• Prior near-neighbor pressure: Codex, The Collective Brain Of Awakening; Codex, Solitude Is Not Isolation; the More Minds Multiply Guesses, Not Tests audit. These lower novelty and force a distinct axis.
