Index fund investing applies the loser's game strategy to markets

The "know-nothing investor" strategy: buy a broad index fund every month for 30-40 years. No stock picking, no market timing. Average performance, but sustained for an above-average duration.

The result is likely top-1% outcomes — not because of special skill, but because most amateur investors beat themselves trying to pick winners. They underperform the index, trade at the wrong time, chase recent returns. The index buyer avoids all of that by design.

The amateur who picks individual stocks is playing a winner's game they're not equipped to win. The amateur who buys the index and holds is playing a loser's game correctly: minimize errors, stay in play, let time do the work.

[!TIP] The edge here isn't knowledge — it's discipline. Anyone can buy an index fund. Most people won't hold through a 40% drawdown without abandoning the strategy.

Source claim: Passive index-buying over decades likely outperforms active stock picking for amateur investors because it avoids the errors that active amateur investors reliably make.
