Scott H Young — “12 Things I Changed My Mind About” (TL;DR)

After reading 100+ books for his Foundations project, Scott argues that real learning often means unlearning. Here’s the distilled version:

1. Intelligence isn’t fixed.
   Effort, strategy, and environment matter more than raw talent.

2. Productivity isn’t about hacks.
   Systems and consistency beat clever tricks.

3. Passion isn’t found — it’s built.
   Interest deepens through skill and exposure.

4. Multitasking doesn’t work.
   Focused attention wins.

5. Discipline isn’t everything.
   Environment design often matters more than willpower.

6. You don’t need extreme habits.
   Small, repeatable changes compound.

7. Debate doesn’t equal truth-seeking.
   Many arguments are about status, not accuracy.

8. Certainty is overrated.
   Holding beliefs loosely improves learning.

9. Reading widely changes you.
   Diverse perspectives reduce blind spots.

10. Experts disagree more than we think.
    Complexity resists simple answers.

11. Action beats overthinking.
    Experimentation clarifies faster than analysis.

12. Changing your mind is strength, not weakness.
    Updating beliefs = intellectual maturity.
