What is Narrative bias?
Believing the better story over the better data.
Narrative bias is the pull to believe a compelling story over the duller data. The human mind is built for stories, so a vivid tale about a company's transformative future can override the unglamorous numbers — the revenues, margins, and cash flows — that actually determine returns.
Markets love narratives, and they routinely overprice exciting stories and underprice boring-but-solid businesses. A gripping vision of disruption attracts buyers and a rich valuation regardless of whether the numbers support it, while a dull, profitable company with no story languishes. That gap is exactly where disciplined, numbers-first investors find their edge: by insisting the data justify the story, they avoid overpaying for narratives and can pick up sound businesses the crowd finds boring.
Narrative bias tips the scales toward a compelling story over the duller numbers, so markets overprice exciting tales and underprice solid but boring businesses — exactly where disciplined investors find edge.
For example
A company with a thrilling story trades at a sky-high valuation its actual revenue can't justify, while a dull, cash-generating rival is ignored — the market pricing the story over the numbers.

Narrative bias matters because the most exciting stories are often the worst investments, and the dullest businesses can be the best bargains. Stories drive prices away from what the fundamentals warrant, creating overpriced hype and underpriced boredom. Insisting that the numbers back up the narrative — and being willing to own an unexciting company the story-chasers ignore — is a durable source of edge precisely because it runs against how the mind naturally works.
⚠ Paying up for a story the numbers don't support
A thrilling narrative can justify almost any price in your imagination, but the returns ultimately come from revenues, margins, and cash flows. Buying a company because its story is exciting, without checking whether the fundamentals could ever support the valuation, is how investors overpay for hype. Let the data, not the tale, set what you'll pay.
