Earned Dogmatism in Finance: When Expertise Breeds Rigidity
Bill Miller's success at Legg Mason, followed by his 2008 downfall, exemplifies earned dogmatism—the tendency for expertise to breed rigidity, hindering adaptation to new information, as studied by Ottati (2015) and Chaney (2025).
- What are some specific examples of earned dogmatism in financial life planning?
- Overconfidence in one investment area (e.g., real estate) can lead to neglecting other aspects of financial planning. Mental accounting, where funds are rigidly allocated, ignores the fungibility of money, potentially hindering optimal resource allocation during emergencies.
- What is the antidote to earned dogmatism, and why is it crucial for financial advisors?
- The antidote is continuous learning and intellectual curiosity. For financial advisors, this is crucial because the field constantly evolves. Advisors who embrace curiosity are better positioned to adapt to changes and serve their clients effectively.
- How does earned dogmatism manifest in financial decision-making, and what are its consequences?
- Earned dogmatism leads to biased information processing and resistance to alternative viewpoints. In finance, this can result in overconfidence (like Miller's 2008 bets) or underconfidence, hindering adaptation to market shifts and potentially causing significant financial losses.
