Unlike surgery or engineering, success in finance depends more on behavior than intelligence. A disciplined amateur who controls greed and fear can outperform a PhD from MIT who makes poor behavioral decisions. This highlights that temperament is the most critical variable for long-term financial success.

The funding gap isn't just about discrimination. Women, on average, are more risk-averse and often build passion-led businesses that don't fit the hyper-growth VC model. They favor bootstrapping and debt, leading to higher survival rates but fewer billion-dollar 'unicorns,' reframing the definition of entrepreneurial success.

A Wall Street Journal experiment pitted a monkey throwing darts at a stock list against professional traders. Over a ten-year span, the monkey's long-term, passive 'buy-and-hold' strategy won. This demonstrates the power of long-term investing over short-term, active trading.

Contrary to the stereotype of a hyperactive day trader, the average Robinhood user trades 40 times per year—the same as a Schwab self-directed customer. With 95% retention and 5x account balance growth over three years, their behavior indicates a more traditional, long-term approach to investing, not reckless gambling.

A study highlighted by Michael Lewis found men systematically overestimate their knowledge, while women underestimate theirs. This cognitive bias is a major risk in investing and leadership. The anecdote of a man confidently miscorrecting "Marie Curie" to "Mariah Carey" perfectly illustrates this dangerous self-assurance.

"Bold" investors chase high returns but risk ruin, yielding great arithmetic but poor geometric returns. "Shy" investors are conservative, surviving longer and compounding steadily, mirroring chipmunks who squawk often but live more seasons. This highlights an evolutionary trade-off between risk and survival.

Vanguard and Berkshire Hathaway data shows men underperform women in long-term returns despite taking more risks. Men trade more frequently, incurring fees and making emotional timing mistakes ("tinkering"). Women's cautious, less active approach allows compounding to work more effectively.

Data reveals a market inefficiency in Japan's venture landscape: female-founded companies raise less capital at lower valuations but achieve IPO valuations 1.5 times greater than their male-led peers. This creates a clear arbitrage opportunity for investors to buy in at a discount and exit at a premium.

Finance is one of the only fields where behavior is more important than knowledge. An amateur with no formal training but immense patience can financially outperform a highly educated expert who succumbs to fear and greed. It's not about what you know; it's about how you act.
