If Nothing Could Disprove It, It's Not Really a Claim
It's tempting to treat an idea as solid because so much seems to support it. But a claim only earns real confidence if there's some possible evidence that would prove it wrong. If a theory can explain literally any outcome, it isn't being tested — it's just being confirmed.
Put Your Own Ideas at Risk
- Before defending a belief, ask: what evidence would make me abandon it?
- If the answer is 'nothing,' treat that as a warning sign, not a strength.
- Look for the test that could fail, not just the example that succeeds.
