Jim O'Shaughnessy: The Psychology of Investing

— Jim O'Shaughnessy explains how human psychology and evolutionary biology drive poor investment decisions, particularly during volatility and market manias.

— Historical bubbles (South Sea, dot-com, NASDAQ) follow identical patterns to current crypto cycles, with irrational fear and greed as constant drivers.

— Quantitative, rules-based investing outperforms discretionary management because algorithms remove emotional override; O'Shaughnessy has never emotionally overridden a model in 30+ years.

— Bitcoin's deflationary model presents theoretical store-of-value appeal but faces practical barriers: extreme price volatility (20–30% swings) undermines confidence and currency adoption.

— Institutional adoption and regulatory clarity are critical milestones for crypto legitimacy; without them, crypto remains speculative rather than functional currency.

— Momentum strategies are the most applicable quantitative tool for crypto markets, since fundamental analysis is absent.

— Build an investment strategy aligned with your own psychology: test whether you can truly withstand a 50%+ drawdown before committing capital; use journaling to document real-time decisions and avoid hindsight bias.

— Accept that price is often the only meaningful diligence metric; most assets become worth buying at the right price, so focus your effort on entry discipline rather than perfect asset selection.

— If trading crypto, adopt momentum-based models with volatility weighting rather than attempting fundamental valuation; recognize that until Bitcoin stabilizes to single-digit price swings, it cannot function as a true store of value or currency.
