The perceived overconfidence of great investors may not be a cause of their success, but an effect. It is likely a product of survivorship bias—as we don't see the overconfident who failed—and the practical need to project extreme confidence to attract and retain limited partners' capital in a competitive industry.

There's a surprising disconnect between the perceived brilliance of individual investors at large, well-known private equity firms and their actual net-to-LP returns, which are often no better than the market median. This violates the assumption that top talent automatically generates outlier results.

The concept of a 'risk-loving' investor is a myth. These individuals are simply exceptionally skilled at psychologically minimizing perceived risks to justify their decisions. They convince themselves the risk is far less than it truly is in order to pursue the reward.

Highly intelligent individuals often overestimate their investing prowess due to the "curse of knowledge." Expertise in one domain doesn't translate to financial markets, and their intelligence enables motivated reasoning, allowing them to rationalize failures rather than learn from them.

Success in investing isn't about constant wins. Sir Paul Marshall notes that a top-tier manager may only have a 54% success rate. This means being wrong almost every other day, which serves as a powerful, daily antidote to the hubris that can destroy investment careers.

True success requires humility to accept mistakes and change your mind, whereas arrogance leads to ruin. The most successful investors are notably humble people.

Advice from successful people is inherently flawed because it ignores the role of luck and timing. A more accurate approach is to study failures—the metaphorical planes that didn't return.

Shelby Davis Jr.'s fund was a top performer in its first year, leading to overconfidence. This early success, often a product of market whims rather than superior process, caused him to misattribute luck to skill, resulting in poor performance in subsequent years.

According to Ken Griffin, legendary investors aren't just right more often. Their key trait is having deep clarity on their specific competitive advantage and the conviction to bet heavily on it. Equally important is the discipline to unemotionally cut losses when wrong and simply move on.

Charlie Munger's comment on Elon Musk—"Never underestimate the man who overestimates himself"—highlights a paradox. Extreme self-belief, often a flaw, can be a founder's greatest asset, fueling the audacity required to pursue goals that rational minds dismiss as impossible.
