The cognitive biases that affect our financial decisions

cognitive biases

In the financial world, every decision we make can have a significant impact on our economic stability and future well-being. From investment and saving decisions to spending choices, our financial actions determine how we perform in the economic realm. Therefore, it is essential that our decisions are as rational and informed as possible.

Making rational financial decisions involves carefully evaluating all available options, considering the associated risks and rewards, and basing our choices on sound, objective information. Informed financial decision making allows us to maximize opportunities, minimize risks, and work toward our long-term financial goals.

Although we all strive to make rational financial decisions, our minds are often influenced by cognitive biases, which are automatic, subconscious thought patterns that can distort our perception and judgment. These cognitive biases can lead us to make irrational and unwise financial choices, negatively affecting our financial well-being.

Cognitive biases can arise due to our inherent human psychology and previous experiences. Some of the most common biases that influence our financial decisions include confirmation bias, loss aversion bias, and anchoring bias.

  1. Confirmation bias occurs when we search for information that supports our existing beliefs and discount or ignore data that contradicts those beliefs. This bias can lead us to make financial decisions based on a biased and partial view of reality.
  2. The loss aversion bias leads us to fear losses rather than value potential gains. As a result, we can avoid risks that could be beneficial in the long run, preventing us from taking advantage of valuable investment opportunities.
  3. Anchoring bias makes us cling too tightly to an initial benchmark or starting point, influencing the way we value assets or make price-related financial decisions.

Recognizing and understanding these cognitive biases is essential to avoid falling into irrational thought patterns and to make more informed and strategic financial decisions. In this blog, we'll explore each of these biases in detail, provide illustrative examples, and offer practical suggestions for overcoming them. By doing so, we hope to help you make more rational financial decisions and achieve your financial goals with greater confidence and success.

Confirmation bias

Confirmation bias is a cognitive thought pattern that leads us to selectively seek, interpret, and remember information that confirms our pre-existing beliefs or hypotheses, while ignoring or dismissing information that contradicts those beliefs. In other words, we tend to look for evidence to support what we already believe, thus reinforcing our convictions, even if they are not backed by solid data.

This bias can manifest itself in a variety of situations, from political discussions to financial decisions. In the context of finance, confirmation bias can negatively affect our ability to make rational and informed decisions, as it causes us to ignore important factors that could alter our perception of an investment or financial strategy.

Confirmation bias influences our financial decisions by limiting our exposure to unbiased and objective information. When faced with a financial decision, we tend to look to sources that reinforce our pre-existing beliefs, which can lead to a distorted and skewed view of the financial landscape. This bias can have several negative effects, such as:

  1. Ignoring Potential Risks : If we are convinced that an investment will be successful, we may ignore warning signs or associated risks, which can result in significant financial loss.
  2. Missing Valuable Opportunities – By focusing solely on information that supports our current beliefs, we could miss out on valuable investment opportunities that don't fit our limited perceptions.
  3. Staying Stuck in Bad Decisions : Confirmation bias can lead us to hold on to an investment or financial strategy even when the evidence suggests it's ill-advised, preventing us from changing course in time.

Illustrative example of confirmation bias in investment

Suppose an investor has a strong belief that a certain industry will experience rapid growth in the future because of some positive news he has heard. As he does more research on that industry, he actively seeks reports, analysis and opinions that support his belief. If he finds some optimistic reports, he feels more confident in his decision to invest in shares of companies in that industry and makes his decision without fully considering contrary information or possible associated risks.

Suggestions to avoid confirmation bias in our financial decisions:

  1. Keep an open mind : Recognize that we are all subject to confirmation bias, and strive to be willing to consider different perspectives and sources of information before making important financial decisions.
  2. Look for unbiased information : Look for news sources and financial analysis that are not biased towards a particular perspective. Consult various sources before making decisions.
  3. Examine your beliefs : Reflect on your financial beliefs and consider whether you are seeking information just to reinforce them. Challenge your assumptions and look for solid evidence to support your decisions.
  4. Seek objective financial advice : Consult professional financial advisors who can offer an unbiased and objective perspective on your financial decisions.

By taking steps to avoid confirmation bias, we can improve our financial decision making and ensure it is informed by sound data and more rational approaches.

Loss aversion bias is a cognitive bias that reflects our tendency to feel the pain of loss more intensely than the pleasure of equivalent gains. In other words, we are more inclined to avoid potential losses than to seek profit opportunities, even if the potential benefits far outweigh the risks involved.

This bias is closely related to our desire to protect what we already have and avoid the uncertainty that comes with risk. As a result, we may take more conservative financial decisions or even lock in the possibility of losses, which can limit our opportunities for growth and diversification.

Loss aversion can affect our financial decisions in several ways:

  1. Excessive caution in investments : Loss aversion can lead us to opt for low-risk investments, such as savings accounts or bonds, instead of exploring more lucrative investment opportunities, such as stocks or assets with higher yields.
  2. Missed Growth Opportunities : By avoiding situations that involve risk, we may miss out on valuable investment opportunities that could significantly increase our wealth over the long term.
  3. Premature Selling of Investments : Loss aversion can lead us to sell assets in the midst of a market decline, resulting in realized losses before prices can recover.

Illustrative example of loss aversion bias in portfolio management

Let's imagine an investor who has invested a considerable amount in shares of a particular company. Over time, the value of this company's shares begins to decline due to challenges in the market. Although the investor knows that historically the market has experienced ups and downs, loss aversion leads him to sell his shares quickly to avoid further losses. However, shortly after selling, the market recovers, and the company's shares rise again, resulting in a missed opportunity for the investor to recoup their initial investment and even make a profit.

Tips to avoid loss aversion bias and make more balanced decisions

  1. Set Clear Goals : Define your long-term financial goals and understand that certain investments carry a degree of risk necessary to achieve those goals.
  2. Diversify your portfolio : Spread your investments across different assets and asset classes to reduce the impact of individual losses and improve overall return potential.
  3. Take a long-term approach : Avoid making impulsive decisions based on short-term market movements. Keep a long-term perspective to take advantage of sustained growth opportunities.
  4. Consult Financial Advisors : Seek the advice of qualified and objective financial professionals to obtain a balanced perspective on your investment decisions.
  5. Learn from losses : Instead of fearing losses, use these experiences as opportunities to learn and improve your investment strategies.

By recognizing and addressing loss aversion, we can make more balanced and strategic financial decisions, taking advantage of growth opportunities while appropriately managing associated risks.

Anchorage bias

Anchoring bias is a pattern of cognitive thinking that manifests itself when we excessively rely on the first information or value we receive when making a decision, and then adjust our evaluations or judgments around that initial "anchor." This anchor can be any number, benchmark, or information we receive before making a decision, and it can significantly influence our subsequent perceptions and assessments, even if that initial information is irrelevant or unrealistic.

In the financial context, anchoring bias can affect our asset valuation, investment return expectations, and trading strategies.

Anchoring bias can have a profound impact on our financial decisions in a number of ways:

  1. Improper Asset Valuation : If we are given an asking price or suggested valuation for an asset, we tend to stick with that figure, even if there is evidence to support a different, more accurate valuation.
  2. Pricing in Negotiations : When we negotiate, the first price proposed or quoted can become the anchor point for subsequent negotiations, which can lead us to accept less favorable terms or not explore more beneficial alternatives.
  3. Investment Return Expectations – If an asset has experienced exceptional performance in the past, we may lock onto that rate of return when evaluating our future expectations, which could lead to unrealistic or unbalanced investment decisions.

Illustrative example of anchoring bias in asset valuation

Suppose an investor is interested in buying shares of a company and seeks opinions about its fair market price. If the first opinion he finds suggests that the fair price is $100 a share, that number is likely to become the anchor for his valuation. Even if subsequent analysis indicates that the fair price is actually $80 per share due to changes in the market and the company's fundamentals, the investor may find it difficult to accept that new valuation and remain locked in at the initial price of $100.

Suggestions to avoid anchoring bias and make more objective decisions

  1. Conduct Independent Research : Seek multiple sources and analysis before making major financial decisions, avoiding relying solely on a single reference or initial valuation.
  2. Set rational limits : Define reasonable ranges of prices or valuations instead of basing your decisions on a single number. These ranges can help you assess the financial context more objectively.
  3. Reflect on your decision-making process : Recognize anchoring bias as a possibility and reflect on how the initial anchoring may be influencing your judgment. Consider adjusting your assessments as you gain new information.
  4. Seek expert help : Consult financial advisors or other professionals to get an objective and professional perspective on your financial decisions.

By consciously addressing anchoring bias and taking a more objective approach when making financial decisions, we can improve our valuations and expectations, enabling us to make more informed and strategic decisions on our path to financial success.

How to make more rational financial decisions

The first step to making more rational financial decisions is to recognize and understand the cognitive biases that can influence our choices. Accepting that we are all subject to biases such as confirmation bias, loss aversion, and anchoring bias allows us to become more aware of how these biases can affect our financial perceptions and judgments. By recognizing our biases, we can take steps to prevent them from distorting our decisions and pursue a more objective and balanced approach.

Making rational financial decisions requires a solid foundation of information. It is essential to seek information from diverse and objective sources to have a more complete and accurate view of the financial landscape. Consulting different perspectives, expert analysis and unbiased sources allows us to gain a deeper understanding of the options available and the implications of our financial decisions. By accessing objective information, we can reduce the influence of our cognitive biases and make more informed decisions.

Consult financial experts for advice

While it is important to make financial decisions independently, consulting financial experts can provide valuable guidance and advice. Professional financial advisors have specialized knowledge and experience in various aspects of the financial world. By seeking their guidance, we can gain unbiased perspectives and personalized strategies that are tailored to our goals and specific financial situation. A good financial advisor can also help us avoid biases and irrational emotions that could affect our decisions.

Establish a long-term financial plan and stay focused on goals

An effective way to make sound financial decisions is to establish a solid long-term financial plan. Defining clear and realistic financial goals allows us to focus on the big picture and avoid making impulsive decisions based on short-term events or momentary emotions. A well-structured financial plan can also help us avoid the temptation to give in to loss aversion or anchoring bias, as our actions will be aligned with our long-term goals.

In addition, it is important to remain disciplined and persevering in the execution of our financial plan. Along the way, we may face challenges and volatility in the markets, but staying calm and sticking to our plan can help us avoid impulsive decisions and stay on the path to financial success.

In conclusion, making rational financial decisions involves recognizing our cognitive biases, seeking objective information, consulting experts, and establishing a long-term financial plan. By applying these approaches, we can make more informed and balanced decisions that move us closer to our financial goals more effectively and safely.


In this blog, we've explored three common cognitive biases that affect our financial decisions: confirmation bias, loss aversion bias, and anchoring bias. These irrational thought patterns can distort our perception of financial reality and lead us to make uninformed decisions. Confirmation bias makes us seek information that supports our pre-existing beliefs, while loss aversion bias makes us fear losses more than value potential gains. For its part, the anchoring bias leads us to rely too much on initial information and adjust our decisions around it, even if it is irrelevant.

The key to making more rational and successful financial decisions lies in the practical application of the suggestions presented in this blog. As we delve into the financial world, it is important to remember:

  1. Recognize and understand our biases: Let's become aware of our cognitive biases and be willing to challenge our pre-established beliefs to make more objective decisions.
  2. Seek objective information: Let's seek information from various unbiased sources and avoid relying exclusively on a single reference or initial assessment.
  3. Consult financial experts: We have the advice of financial professionals trained to obtain an objective and personalized perspective that helps us achieve our financial objectives.
  4. Establish and maintain a long-term financial plan: Let's set clear financial goals and follow a solid and realistic plan, adapting it as economic circumstances change.

By applying these suggestions, we can improve our financial choices and maximize the potential for economic growth and prosperity. Overcoming cognitive biases allows us to make informed and informed decisions, paving the way to a more secure and successful financial future.
