What is strong opinions loosely held?

Strong opinions loosely held is a concept in personal epistemology: Self-authority does not mean arrogance or certainty. The most powerful form of self-authority is the humble recognition that you are responsible for evaluating evidence and updating your beliefs — even when that means admitting you were wrong.

Example: Your team adopts a technical architecture you championed. Six months in, the evidence is clear: it's not scaling. The arrogant response is to defend the decision because reversing it threatens your credibility. The cowardly response is to say nothing and hope someone else raises the problem. The epistemically humble response — the one that actually requires self-authority — is to say: 'I advocated for this. The data shows it isn't working. Here's what I think we should do instead.' That statement requires more authority over your own mind than the original decision did, because it means overriding your ego's desire to be right.

This concept is part of Phase 31 (Self-Authority) in the How to Think curriculum, which builds the epistemic infrastructure for self-authority.
