Understanding Human biases (Confirmation bias) : A Step-by-Step Guide
In today's fast-paced world, it is crucial to understand the various factors that shape our thoughts, decisions, and actions. One such factor that often goes unnoticed is human biases. These biases, which are inherent in all of us, can significantly impact our perceptions, judgments, and interactions with others. In this blog post, we will delve into the world of human biases, exploring their origins, types, and effects. By shedding light on these hidden influences, we can strive to become more aware of our own biases and work towards making more objective and fair-minded choices.
Human biases refer to systematic patterns of thinking, judgment, and decision-making that deviate from objective and rational assessment of information or situations. These biases are often influenced by a person's background, experiences, emotions, and cognitive shortcuts, leading to skewed perceptions and judgments. Human biases can affect various aspects of life, including social interactions, problem-solving, and decision-making processes.
- Here are some common types of human biases
1. Confirmation Bias
Confirmation bias is our brain's tendency to favor information that supports what we already believe or think, while ignoring or downplaying information that goes against our beliefs. In other words, we often see what we want to see and hear what we want to hear. It can make us more certain in our existing ideas, even if they're not necessarily accurate, and it can lead us to ignore important facts that might challenge our views. To avoid this bias, it's important to stay open to different perspectives and be willing to consider information that might not align with what we currently believe.
- Confirmation bias Traits
1. Selective Information Gathering: People with confirmation bias tend to actively seek out information that confirms their existing beliefs while avoiding or ignoring information that contradicts them.
2. Biased Interpretation: When presented with ambiguous or mixed evidence, individuals with confirmation bias tend to interpret it in a way that aligns with their preconceived notions.
3. Avoidance of Cognitive Dissonance: Confirmation bias helps individuals avoid the discomfort of cognitive dissonance, which is the mental tension that arises when holding conflicting beliefs or attitudes. They prefer information that maintains consistency in their beliefs.
4. Selective Memory: People may remember and recall information that supports their views more readily than information that challenges them, leading to a reinforcement of their biases.
5. Motivated Reasoning: Confirmation bias often involves motivated reasoning, where individuals actively search for reasons to support their existing beliefs and discount evidence to the contrary.
6. Overconfidence: Those affected by confirmation bias tend to be more confident in their beliefs and judgments, even when those beliefs are based on limited or biased information.
7. Resistance to Change: Confirmation bias can make individuals resistant to changing their minds or revising their beliefs when presented with contradictory evidence. They may become more entrenched in their views instead.
9. Influence on Perception: Confirmation bias can shape how people perceive and interpret the world, often reinforcing stereotypes and prejudices.
10. Echo Chambers: In social settings, confirmation bias can lead to the formation of echo chambers or filter bubbles, where people predominantly interact with those who share their views, further reinforcing their biases.
11. Polarization: On a larger scale, confirmation bias contributes to polarization in societies, as individuals and groups become more divided along ideological or belief lines.
12. Belief Perseverance: Even in the face of overwhelming evidence to the contrary, those affected by confirmation bias may persist in their original beliefs.
- example of confirmation bias
Imagine a person who believes that a specific brand of smartphones is the best on the market. Whenever they hear about or read reviews related to smartphones, they tend to focus on and remember positive information about that brand, such as its impressive camera or long-lasting battery life. They might also dismiss or ignore negative reviews or information about other smartphone brands.
In this case, the person is demonstrating confirmation bias by selectively seeking out and emphasizing information that supports their belief in the superiority of their chosen smartphone brand, while disregarding or downplaying information that contradicts it. This bias can make them less open to considering alternative options or acknowledging the strengths of other brands.
- Psychologist on Confirmation bias
Psychologists have extensively studied confirmation bias as a cognitive bias that affects human thinking and decision-making. Confirmation bias has been a subject of interest in various branches of psychology, including cognitive psychology, social psychology, and behavioral economics. Here are some insights from psychologists on confirmation bias:
1.Leon Festinger: Festinger is known for his work on cognitive dissonance theory, which is closely related to confirmation bias. He proposed that individuals tend to seek out information that confirms their existing beliefs to reduce the discomfort of cognitive dissonance (the psychological discomfort arising from holding conflicting beliefs).
2.Daniel Kahneman: A Nobel laureate in economics, Kahneman's research on cognitive biases, including confirmation bias, has been influential. He co-authored the book "Thinking, Fast and Slow," which discusses how people often rely on intuitive thinking (fast) and are prone to cognitive biases, including confirmation bias.
3.Amos Tversky: Tversky collaborated with Kahneman and made significant contributions to the understanding of cognitive biases. Together, they developed the concept of "anchoring and adjustment," which is related to confirmation bias as people tend to anchor their beliefs and then adjust them based on new information.
4.Carol Tavris and Elliot Aronson: These psychologists have explored confirmation bias in the context of cognitive dissonance and motivated reasoning. Their work highlights how people often engage in motivated reasoning to protect their self-concept and beliefs, leading to confirmation bias.
5.Lee Ross: Ross coined the term "naive realism," which relates to confirmation bias. Naive realism suggests that people tend to believe that their perspective is objective and rational, leading them to perceive others as biased when they hold different views.
6.Deborah Mayo: A philosopher of science, Mayo has discussed the role of confirmation bias in scientific reasoning and hypothesis testing. Her work highlights the importance of critical thinking and the need to consider alternative hypotheses to avoid confirmation bias in scientific research.

- how to overcome Confirmation biases?
Overcoming confirmation bias can be challenging because it's a natural cognitive bias that affects everyone to some degree. However, there are strategies you can employ to mitigate its effects and make more objective and well-informed decisions:
1.Be Aware of Your Bias: The first step in overcoming confirmation bias is to acknowledge that it exists and that you may be prone to it. Self-awareness is crucial in recognizing when you are favoring information that confirms your beliefs.
2.Seek Diverse Information: Actively seek out information from diverse sources and with different viewpoints. This can help you gain a more comprehensive understanding of a topic and reduce the impact of confirmation bias.
3.Challenge Your Beliefs: Regularly question your own beliefs and opinions. Ask yourself why you hold a particular belief and whether there is solid evidence to support it. Be open to changing your mind if new evidence emerges.
4.Practice Critical Thinking: Develop critical thinking skills to evaluate information objectively. This includes assessing the credibility of sources, looking for biases in the information presented, and considering alternative explanations.
5.Engage in Devil's Advocacy: Try to argue against your own beliefs or viewpoints. This exercise can help you see the weaknesses in your arguments and consider alternative perspectives.
6.Embrace Uncertainty: Accept that not all questions have definitive answers. It's okay to be uncertain about certain issues and to resist the temptation to jump to conclusions based on limited information.
7.Use Bayesian Thinking: Apply Bayesian reasoning, which involves updating your beliefs based on new evidence. Instead of holding steadfast to your initial belief, be willing to adjust it as you encounter more information.
8.Diversify Your Social Circle: Interact with people who have different backgrounds, beliefs, and experiences. Engaging in discussions with diverse individuals can expose you to new ideas and challenge your existing biases.
9.Take Breaks from Social Media: Social media platforms often reinforce confirmation bias by showing you content that aligns with your existing views. Consider taking breaks from social media or diversifying your online connections to reduce this bias.
10.Educate Yourself on Cognitive Biases: Learn about cognitive biases, including confirmation bias, and how they can impact decision-making. Understanding these biases can help you recognize them in yourself and others.
11.Be Mindful of Emotional Responses: Recognize when your emotional reactions are influencing your judgment. Strong emotional responses can lead to confirmation bias, as people often seek information that validates their emotions.
12.Use Decision-Making Tools: When making important decisions, consider using decision-making frameworks like the SWOT analysis, cost-benefit analysis, or decision trees to structure your thinking and reduce bias.
Overcoming confirmation bias is an ongoing process that requires effort and self-reflection. It's important to remain open to the possibility that your beliefs may change as you encounter new information and perspectives. By actively working to reduce confirmation bias, you can make more rational and well-informed decisions.
- Peter Wason Confirmation bias task
Peter Cathcart Wason (1924-2003) was a British psychologist known for his pioneering work in the field of cognitive psychology, particularly for his research on reasoning and confirmation bias. He conducted a famous study known as the "Wason selection task," which shed light on how confirmation bias influences human decision-making and problem-solving.
The Wason selection task is a classic experiment that illustrates confirmation bias in a simple rule-learning context. In this experiment, participants are presented with a logical task that involves four cards, each with a letter on one side and a number on the other side. The task is to determine which cards need to be turned over to test whether a rule is true.
Here's a simplified version of the task
You are shown four cards: A, B, 1, and 2. Each card has a letter on one side and a number on the other. The rule to be tested is: "If there is a vowel on one side of the card, then there must be an even number on the other side."
Participants are asked to choose which card or cards they want to turn over to verify the rule.
Wason's findings demonstrated that participants often selected cards that confirmed their preconceived notions and neglected cards that could potentially disconfirm the rule. For example, many participants would choose to flip over the A card (to confirm the presence of a vowel) and the 2 card (to confirm the presence of an even number). However, they would often neglect to flip over the B card, which could potentially disconfirm the rule if it had an even number on the other side.
Wason's research highlighted how people tend to seek information that confirms their hypotheses or beliefs (in this case, the rule), even when it's more important to seek out disconfirming evidence. This tendency to favor confirmation over disconfirmation is a key aspect of confirmation bias.
Wason's work on the selection task and confirmation bias has had a lasting impact on the field of psychology and has contributed to our understanding of human reasoning and decision-making processes. It has also been influential in discussions about critical thinking, scientific inquiry, and the importance of considering alternative hypotheses when evaluating information.
