Memoirs & biographies

Textbooks present decisions already tidied up, with the outcome known. Biographies show the real process: incomplete information, cash-flow pressure, partner conflicts, and choices made without knowing whether they will work. The value lies in observing the reasoning that preceded the result, not in copying conclusions that depend on an unrepeatable context.

Read them assuming survivorship and self-justification bias: the author controls the narrative and tends to downplay luck and mistakes. Phil Knight's «Shoe Dog» is unusually candid about its liquidity crises, but even there the counterfactual is missing. Cross-reading them against journalist-written biographies — Isaacson, Stone, Osorno — corrects much of that distortion.

Isaacson works with access to his subject: extensive interviews, cooperation and, in exchange, a gaze that tends toward understanding the person. Investigative journalism, like John Carreyrou's «Bad Blood», begins from conflict with the company and from cross-checking mutually hostile sources. Both are useful, but they produce portraits shaped by different incentives.

Not directly. Understanding a company's culture and capital allocation helps interpret its accounts, but a biography is no substitute for financial analysis and does not predict future business performance. These are readings for context and judgement, not for security selection.
