William B. Irvine is an author and emeritus professor of philosophy at Wright State University, recognized for his role in the modern resurgence of Stoicism.

## Thinking, Ignorance, and Better Decisions

1. **On Accept That Ignorance Is Inevitable:** Limited mental capacity means everyone is ignorant about vast parts of the world; the important question is whether we recognize the boundary. — [*Reference: William B. Irvine — Stupidity, Reconsidered*](https://morebetterthinking.substack.com/p/stupidity-reconsidered)
2. **On Investigate What Can Affect Your Well-Being:** Remaining ignorant is most costly when the missing knowledge can materially affect your well-being and is available with reasonable effort. — [*Reference: William B. Irvine — Stupidity, Reconsidered*](https://morebetterthinking.substack.com/p/stupidity-reconsidered)
3. **On Use Due Diligence Before Commitment:** A careful thinker investigates before entering an agreement or committing to a consequential course of action. — [*Reference: William B. Irvine — Stupidity, Reconsidered*](https://morebetterthinking.substack.com/p/stupidity-reconsidered)
4. **On Watch for Meta-Ignorance:** Not knowing is less dangerous than not knowing that you do not know, because hidden ignorance can masquerade as confidence. — [*Reference: William B. Irvine — Stupidity, Reconsidered*](https://morebetterthinking.substack.com/p/stupidity-reconsidered)
5. **On Treat Unknown Unknowns as a Risk:** The blind spots outside our awareness can pose a larger threat than the questions we already know we cannot answer. — [*Reference: William B. Irvine — Stupidity, Reconsidered*](https://morebetterthinking.substack.com/p/stupidity-reconsidered)

7. **On Practice Epistemic Humility:** Admitting ignorance demonstrates awareness of the limits of knowledge and can improve later decisions. — [*Reference: William B. Irvine — Stupidity, Reconsidered*](https://morebetterthinking.substack.com/p/stupidity-reconsidered)
8. **On Define Stupidity by Resistance to Correction:** The deepest intellectual failure is not holding a mistaken belief but entering a state in which you are unlikely ever to identify and remove it. — [*Reference: William B. Irvine — Stupidity, Reconsidered*](https://morebetterthinking.substack.com/p/stupidity-reconsidered)
9. **On Choose What and How to Think:** Better thinkers are distinguished less by the volume of mental activity than by their chosen subjects and their method of inquiry. — [*Reference: William B. Irvine — Are You Guilty of Overthinking?*](https://morebetterthinking.substack.com/p/are-you-guilty-of-overthinking)
10. **On Learn Before Drawing Conclusions:** A thinking practice should combine learning about the world with drawing conclusions from what has actually been learned. — [*Reference: William B. Irvine — Are You Guilty of Overthinking?*](https://morebetterthinking.substack.com/p/are-you-guilty-of-overthinking)

12. **On Seek the Optimal, Not the Perfect:** A sound decision may select a bad option when every alternative is worse; perfection is not the relevant standard. — [*Reference: William B. Irvine — Are You Guilty of Overthinking?*](https://morebetterthinking.substack.com/p/are-you-guilty-of-overthinking)
13. **On Exercise Focused Thinking:** Deliberate mental exercise makes concentrated reasoning easier and can turn decision-making into a source of satisfaction. — [*Reference: William B. Irvine — Are You Guilty of Overthinking?*](https://morebetterthinking.substack.com/p/are-you-guilty-of-overthinking)

## Mindcare and Belief Maintenance

Irvine — How to Stress Test Beliefs With AI*](https://morebetterthinking.substack.com/p/i-double-dog-dare-you-to-stress-test)
3. **On Build a Three-Part Mind Program:** Intellectual maintenance combines mindcare to reduce incoming misinformation, mindcleaning to remove false beliefs, and mind expansion to find useful truths. — [*Reference: William B.

5. **On Remove Misinformation That Slips Through:** No information filter is perfect, so a mindcleaning regimen must search for misinformation that passed earlier defenses. — [*Reference: William B. Irvine — How to Stress Test Beliefs With AI*](https://morebetterthinking.substack.com/p/i-double-dog-dare-you-to-stress-test)
6. **On Expand Toward True and Useful Beliefs:** Intellectual growth requires exploring the world for additional beliefs that improve both accuracy and usefulness. — [*Reference: William B.

Irvine — How to Stress Test Beliefs With AI*](https://morebetterthinking.substack.com/p/i-double-dog-dare-you-to-stress-test)

Irvine — How to Stress Test Beliefs With AI*](https://morebetterthinking.substack.com/p/i-double-dog-dare-you-to-stress-test)
12. **On Clean a Small Portion at a Time:** Because the total belief set is enormous, focus each mindcleaning effort on a narrow domain rather than attempting a complete overhaul. — [*Reference: William B. Irvine — Time for Some Mindcleaning?*](https://morebetterthinking.substack.com/p/time-for-some-mindcleaning)
13. **On Seek Sources That Challenge You:** A belief audit should deliberately counter the tendency to consume confirming sources while avoiding disconfirming ones. — [*Reference: William B. Irvine — Time for Some Mindcleaning?*](https://morebetterthinking.substack.com/p/time-for-some-mindcleaning)

Irvine — Time for Some Mindcleaning?*](https://morebetterthinking.substack.com/p/time-for-some-mindcleaning)
