Definition

Cognitive biases are systematic patterns of deviation from norm or rationality in judgment, where individuals rely on subjective judgment rather than objective data.

Review Questions

  • How do cognitive biases challenge the notion of market efficiency?
    • Cognitive biases challenge the notion of market efficiency by demonstrating that investor behavior is often irrational and influenced by psychological factors rather than solely by available information. For example, overconfidence bias can lead investors to underestimate risks, causing them to trade excessively and deviate from rational pricing. This behavior suggests that markets are not always efficient, as prices may not fully reflect all relevant information due to the influence of these biases.
  • In what ways do cognitive biases affect saving and spending decisions among individuals?
    • Cognitive biases significantly affect saving and spending decisions by influencing how individuals perceive risks and rewards. For instance, loss aversion can lead people to avoid investing even when potential gains outweigh potential losses. Additionally, the anchoring effect may cause individuals to base their financial decisions on irrelevant reference points, such as past prices or savings goals, ultimately impacting their financial well-being. Understanding these biases can help individuals make more informed choices about saving and spending.
  • Evaluate the impact of cognitive biases on investor relations and market reactions during periods of financial crisis.
    • During financial crises, cognitive biases can greatly impact investor relations and market reactions by amplifying fear and uncertainty. For example, loss aversion may cause investors to panic sell their assets at a loss, exacerbating market declines. Additionally, confirmation bias might lead investors to ignore contrary evidence about a declining stock or market conditions, resulting in poor decision-making. This interplay between cognitive biases and emotional responses can create a feedback loop that deepens market volatility and complicates recovery efforts.
