Separate the consensus view from the correct one

To outperform, you must be both non-consensus and right — and second-order thinking is how.

Why it works

Marks’ insight is that an edge requires thinking differently and correctly. First-level conclusions are already priced in by everyone who reached them the easy way, so they offer no advantage. Going to a deeper level — what others are missing and why — is the only path to a view that is both different and better. The mechanism is deliberately searching past the obvious shared answer.

How to do it

1. Write the first-level, consensus answer everyone reaches.
2. Ask what that view assumes and where it could be wrong.
3. Form a second-level view only if you can say why the crowd is missing it.

Evidence

A practitioner principle from investing. It is mechanistic reasoning about edge and consensus, not a studied psychological intervention; the value is in the discipline of distinguishing "different" from "correct". (mechanistic)

This is investing wisdom, not a tested technique; its merit is conceptual clarity, not measured outcomes.

Common mistake

Being contrarian for its own sake — different but not better. Non-consensus and wrong is worse than consensus.
