Psychological Drivers Behind Bubbles

The Psychology of Financial Bubbles: Lessons from History

Herd Behavior and Social Contagion

Herd behavior—where investors follow the actions of others rather than undertaking independent analysis—is a key factor in bubble formation. This social contagion effect can rapidly inflate asset prices as collective optimism becomes self-reinforcing. Studies in behavioral finance illustrate how such group dynamics distort market perceptions BehavioralEconomics.com.

Cognitive Biases

Several well-documented cognitive biases contribute to speculative excess:

Overconfidence Bias: Excessive trust in one’s own judgment can lead to an underestimation of risks.
Confirmation Bias: Investors may favor information that confirms their optimistic views while ignoring contradictory data.
Anchoring: Reliance on historical price levels can skew perceptions of current market value even as conditions evolve.

Nobel laureate Daniel Kahneman’s research provides extensive insights into these biases Nobel Prize – Daniel Kahneman.

Criticism and Alternative Perspectives

Although the psychological framework for understanding financial bubbles is well supported, some scholars argue that market fundamentals and structural factors also play significant roles.
