This cognitive bias can significantly influence decision-making, especially in high-stakes environments like stock market investing, where investors often overestimate their abilities and downplay the role of chance or market fluctuations in their outcomes.

Review Questions

• How does self-attribution bias affect the way investors assess their own performance in the stock market?

  • The long-term implications of self-attribution bias can be detrimental for individual investors. By consistently attributing success to personal skill and failure to external factors, these investors may develop an overconfidence that leads them to take undue risks.

Awareness and mitigation of this bias are crucial for cultivating more sustainable investing practices.
