Introduction to Behavioral Finance and Human Decision-Making
Traditionally, economic and financial theory assumes that investors act rationally, evaluating risks and expected returns without bias when making investment decisions. However, behavioral finance research has shown that human nature is often drawn to uncertainty, leading to cognitive biases affecting both our analytical abilities and the structure of decisions we make, rendering them suboptimal.
Recent Study on Investment Decisions During Economic Uncertainty
A recent study, “Exploring the Role of Behavioral Finance in Investment Decisions during Economic Uncertainty” by Mingyu Wei, examines how consistent psychological biases in most individuals distort the structure and nature of economic decisions, particularly in uncertain contexts.
Study Participants and Findings
The study involved 234 participants (50% individual investors and 50% financial professionals) to analyze how these behavioral patterns affected money management decisions. The research identified several significant effects, with the herd mentality being the most prominent bias.
Herd Mentality and Emotional States
Participants tended to imitate perceived collective actions of the group, even contradicting their own analysis. Emotional states like fear or euphoria significantly altered the perception of risk and interpretation of financial information presented to participants.
Personality Traits and Social Media Influence
The study found that personality traits, such as neuroticism or meticulousness, greatly influenced investment strategies. Exposure to news and social media amplified these biases.
Prevalent Cognitive Biases
Overconfidence was a dominant bias, characterized by underestimating risks and overestimating one’s knowledge, leading to a belief in controlling decision outcomes.
Anchoring bias was another prominent bias, favoring initial analysis data, like the initial purchase price of a stock, over other market changes.
Loss aversion was also present, often expressed as decision paralysis due to fear of making mistakes.
Impact on Daily Decision-Making
These biases affect investors of varying experience levels and influence everyday decisions, causing impulsive purchases or incorrect labor-related choices.
The herd mentality explains why we buy “viral” products or make investments (like cryptocurrencies) without understanding their operation and risks, simply because others do so, especially during uncertain periods like high inflation.
Emotions such as panic (fear of loss) or euphoria (irrational desire for quick gains) impact judgment and decision-making.
Overconfidence leads to overspending or taking on excessive debt, affecting men and younger individuals more.
