Regret Theory


Regret Theory is a theory in behavioral economics that postulates people anticipate regret if they make a wrong choice, and they take this anticipation into consideration when making decisions. It suggests that the pain of regret can often outweigh the pleasure of reward. Thus, individuals may base their financial decisions on minimizing potential regret rather than purely on rational choice theory.


The phonetics of the keyword “Regret Theory” would be: /rɪˈɡrɛt ˈθɪəri/

Key Takeaways

  1. Regret Theory is a psychological theory of decision-making under uncertainty, which posits that people make choices based on the anticipation of regret they might experience in the future.
  2. The theory challenges conventional wisdom by describing how individuals might forego rationality in their decisions, instead choosing options that minimize potential regret, even if other options could potentially offer greater rewards.
  3. Regret Theory has been employed in various fields such as economics, finance, and behavioral sciences to model consumer behavior, investment decisions, and other similar phenomena.


Regret Theory is crucial in business and finance as it provides insight into how decisions are shaped by the anticipation of regret. This theory posits that when making decisions, individuals anticipate the regret they might feel if their choice turns out to be sub-optimal, and this anticipation influences their choices. For example, investors might avoid certain investments due to the fear of potential losses and regret, even if the potential for high returns exists. Understanding regret theory helps businesses and financial planners to make more informed decisions by considering emotional factors alongside economic factors in the decision-making process. It also allows for better predictions of consumer behavior and investment decisions, leading to more effective strategies and potentially greater financial success.


Regret theory, a model of decision making developed in finance, is a powerful tool used to understand how individuals make choices under uncertainty. Its main purpose is to offer an alternative perspective to traditional financial theories which assume that individuals act rationally, maximizing their expected utility. Regret theory asserts that people anticipate the emotional impact of regret or disappointment that potentially imminent decisions can generate, and they make their choices to minimize such emotions. This involves not only the absolute outcomes of their decisions but also relative outcomes when compared to alternative outcomes that could have been achieved. Its practical application extends to fields like finance, economics, and behavioral psychology. In finance, it plays a critical role in comprehending investor behavior. Investors can act based upon the regret they may feel if a decision brings a less favorable outcome than a forgone alternative, leading them to often display a preference for safer investments, reflecting their risk-averse nature. Moreover, this theory aids in interpreting market anomalies, contributing to the development of behavioural finance. Regret theory also underscores why consumer and investor biases exist, enabling the development of strategies to counter these biases, thereby enhancing decision-making efficiency and financial outcomes.


Regret Theory in finance and economics refers to the idea that people anticipate regret if they make a wrong choice, and they consider this anticipation when making decisions. Here are some real world examples: 1. Stock Market Investment: Let’s say an investor owned a stock that he decided to sell, and after selling, the price of the stock surged unexpectedly. The investor might feel regret for having sold the stock and missing out on potential profits. This anticipation of such regret might affect his future decision-making, potentially making him hesitant to sell stocks even when it might be strategically wise. 2. Real Estate Purchase: A person may buy an apartment in a certain neighborhood ahead of buying in another upcoming area upon a real estate agent’s advice. If it later turns out that the property value in the unchosen area rises significantly more than the area they bought in, the person might experience regret at not buying in the other area. This regret may impact future purchasing decisions, making them more cautious or indecisive. 3. Retirement Planning: An individual could choose a conservative investment plan for their retirement fund over a more aggressive one. If they later learn that the aggressive plan yielded higher returns, then they might regret their conservative investment decision. This could influence their future retirement planning strategy, perhaps leading them to take more risks to avoid potential regret.In all these examples, the anticipated regret has tangible impacts on investment and purchase decisions, highlighting the influence of Regret Theory in real-world financial and business scenarios.

Frequently Asked Questions(FAQ)
