What is Overconfidence Bias – Types & Examples
Published by at July 11th, 2023 , Revised On October 5, 2023
When making decisions, our minds can sometimes play tricks on us. One common trick is called overconfidence bias.
It means having too much confidence in our abilities and thinking we know more than we actually do. This bias can affect many areas of our lives, like money, work, relationships, and health. Let’s understand overconfidence bias in detail.
What is Overconfidence Bias?
We all have an overconfidence bias that causes us to think highly of our skills, knowledge, and judgment. Here is how we can define overconfidence bias.
‘’Overconfidence bias is a cognitive bias that frequently manifests when our self-confidence is overinflated, leading us to assume we are more capable or educated than we actually are.’’
This bias can benefit and harm our lives, including problem-solving and decision-making. To understand it better, let’s compare the following terms:
Hindsight Bias vs. overconfidence Bias
Hindsight bias refers to the tendency of individuals to perceive past events as having been more predictable than they actually were. It involves the belief that one could have predicted or foreseen the outcome of an event after it has occurred.
On the other hand, overconfidence bias is the tendency to have unwarranted confidence in one’s judgments, abilities, or beliefs. It involves an exaggerated sense of certainty about one’s knowledge or skills.
While hindsight bias distorts our memory of past events, overconfidence bias leads us to overestimate our abilities and underestimate risks or uncertainties. Both biases can influence decision-making and have potentially negative consequences.
| Bias | Definition | Key Characteristics |
| Hindsight Bias | Perception of past events as more predictable than they were | Belief in the ability to predict outcomes in hindsight |
| Overconfidence Bias | Unwarranted confidence in one’s judgements, abilities or beliefs | Exaggerated certainty, underestimation of uncertainties. |
Confirmation Bias vs. overconfidence
Confirmation bias is the tendency to seek and interpret information that confirms preexisting beliefs, while overconfidence bias is the inflated belief in one’s abilities. While confirmation bias affects information processing, overconfidence bias impacts self-assessment of skills and judgment in decision-making.
| Confirmation Bias | Overconfidence Bias | |
| Definition | The tendency to seek, interpret, and favor information
that confirms one’s pre-existing beliefs or hypotheses. |
The tendency to overestimate one’s abilities, knowledge,
or predictions, leading to excessive confidence. |
| Bias Type | Cognitive Bias | Cognitive Bias |
| Characteristics | – Selectively seeking and interpreting information that
supports existing beliefs. |
– Overestimating one’s own knowledge or capabilities. |
| – Having unwarranted confidence in predictions or outcomes. | ||
| – Ignoring or discounting information that contradicts existing beliefs. | – Failing to accurately assess one’s limitations or risks. | |
| – Underestimating the possibility of failure. | ||
| Examples | – A person only seeking out news articles that align with their political views. | – A person believing they are an expert in a subject despite limited knowledge or experience. |
| Impact | – Reinforces existing beliefs, potentially hindering
objectivity and openness to new ideas. |
– Can lead to poor decision-making due to overestimating one’s capabilities or underestimating risks. |
| – May prevent critical evaluation and discovery of new
information or perspectives. |
– May result in taking unnecessary risks or failing to adequately prepare. |
Overconfidence Bias Vs Dunning Kruger Effect
Overconfidence bias refers to the tendency to inflate belief in one’s abilities, knowledge, or judgment. It leads individuals to overestimate their competence and accuracy in decision-making, often underestimating risks or uncertainties.
On the other hand, the Dunning-Kruger effect is a cognitive bias where individuals with low ability or knowledge in a particular domain mistakenly assess their abilities as being much higher than they actually are. It is characterised by a lack of self-awareness and an inability to evaluate one’s competence accurately.
Does Overconfidence Bias Matter?
Undoubtedly, overconfidence bias is a significant issue that can affect our lives significantly. It is important because it influences our decisions, causing us to make bad decisions and possibly hazardous errors.
Overconfident people may underestimate hazards, exaggerate their skills, and ignore opposing points of view or new facts. Financial losses, failed relationships, missed chances, and other undesirable results may result.
Overconfidence bias can also prevent one from developing personally and from learning. We become less receptive to fresh perspectives, feedback, and helpful criticism when we think we already know everything or are incapable of making mistakes.
What are the Different Types of Overconfidence Bias?
Here are three common types of overconfidence bias:
Overestimation of Abilities
This overconfidence bias occurs when individuals overestimate their skills, knowledge, or performance in a particular area. For example, someone may believe they are an above-average driver, even if the evidence suggests otherwise. This overestimation can lead to risky behaviours and poor decision-making.
The Illusion of Control
The illusion of control refers to the tendency to believe we have more control over outcomes than we actually do. People experiencing this bias may think they can influence or manipulate events largely determined by chance or external factors. This can lead to excessive risk-taking in gambling, investing, or even personal relationships.
Overoptimism About Future Outcomes
This type of overconfidence bias involves having an excessively positive outlook. Individuals may underestimate the likelihood of negative events or overestimate the probability of positive outcomes.
Examples of Over Confidence Bias in Daily Life
Example of Overconfidence Bias in Decision Making
What is overconfidence bias in decision-making? Let’s understand it with an example. Consider a stock trader who has made profitable trades and grown confident in their abilities. Through overconfidence, they can begin making riskier financial choices without carefully weighing the possible drawbacks.
They might think they can continuously outperform the market and correctly forecast market moves, which motivates them to allocate a sizable amount of their portfolio to high-risk investments without taking appropriate precautions.
Example of Overconfidence Bias in the Workplace
An example of overconfidence bias in the workplace is when a salesperson consistently overestimates their ability to close deals.
Despite encountering challenges or receiving feedback indicating otherwise, they firmly believe they can secure every sale. This bias can lead to unrealistic sales projections, overpromising to clients, and a failure to adapt strategies when faced with setbacks.
Example of Overconfidence Bias in Finance
Investor affected by overconfidence bias in finance believes they possess superior abilities and knowledge compared to others. This overconfidence bias example reflects that they may excessively trade or make bold investment decisions based on their unwarranted self-assurance.
However, this overestimation of their skills and underestimation of market uncertainty can lead to poor decision-making. They might need to assess risks adequately, ignore warning signs, or neglect proper diversification.
As a result, they may experience significant financial losses when their predictions prove inaccurate, and their overconfidence is revealed to be unfounded.
Overconfidence bias behavioural finance refers to the tendency of individuals to have an inflated belief in their abilities, knowledge, and judgment when making financial decisions. This bias leads them to overestimate the accuracy of their predictions and the likelihood of positive outcomes.
Overconfidence Bias in Investing
Overconfidence bias in investing is when an investor’s excessive belief in their abilities inflates confidence in their investment decisions. They may overestimate their knowledge and skills, assuming they can consistently outperform the market.
This overconfidence cognitive bias can manifest in various ways, such as excessive trading, taking on higher risks, or neglecting thorough research and analysis.
As a result, overconfident investors may ignore warning signs, fail to adequately assess risks, or become overly optimistic about the potential returns.

How to Avoid Overconfidence Bias?
Dealing with overconfidence bias requires self-awareness and a willingness to challenge our own assumptions and beliefs. The following are some strategies on how to overcome overconfidence bias:
-
Seek Input and Different Viewpoints
Proactively solicit the opinions of others and implore them, to be frank in their evaluations of your concepts, actions, or performance. Accept different points of view and be receptive to criticism. Your understanding of your talents and shortcomings can improve as a result.
-
Consider Alternate Viewpoints
Actively seek out alternative perspectives and consider many viewpoints rather than depending exclusively on your own judgments and ideas. Discuss debates, investigate the subject, and consider opposing viewpoints. This can assist you in developing a more thorough grasp of a scenario.
-
Collect and Analyse the Data
Don’t only go with your gut or intuition; base your conclusions and judgements on facts. Before making judgements, gather information, study, and examine pertinent material. You can make more intelligent selections due to this.
-
Adopt a Growth Mindset
Think with an emphasis on ongoing learning, development, and adaptation. Realise your limitations and the fact that there is always potential for improvement. Accept challenges and view defeats as educational opportunities rather than personal failures.
-
Keep a Record of your Past Achievements
This can assist you in creating a more accurate and realistic view of your skills. Thinking back on prior experiences is beneficial since it can teach you important lessons.
-
Self-Reflection and Mindfulness Exercises
Make it a habit to reflect on your actions and to be mindful. Examine your biases, feelings, and thoughts on a regular basis. This can assist you in becoming more conscious of any tendencies towards overconfidence and allow you to change course as needed.
