Definition
What is it?
Confirmation bias is when we look for, remember, and interpret information in a way that confirms what we already believe or want to believe. It means we prefer information that agrees with us and tend to ignore information that doesn't.
Simple Example
Quick Example
Imagine you think your favourite cricket team, the Chennai Super Kings, is the best. When you read news about cricket, you might only pay attention to articles that praise CSK and easily forget about articles that talk about their losses or other teams' victories. You are confirming your existing belief.
Worked Example
Step-by-Step
Let's say your friend tells you that eating pani puri every day makes you super smart.
---Step 1: You already like pani puri and want to believe this is true.
---Step 2: You decide to search online for 'pani puri benefits for brain'.
---Step 3: You find a blog post that talks about 'healthy street food options' and briefly mentions some ingredients in pani puri are good for health. You focus on this part.
---Step 4: You ignore other search results or articles that talk about the hygiene risks or high salt content in pani puri, because they don't support your belief.
---Step 5: You conclude, 'See, I knew it! Pani puri makes you smart!'
---Answer: This shows confirmation bias because you only looked for and accepted information that matched what you already wanted to believe.
Why It Matters
Understanding confirmation bias helps us make better decisions and think more clearly. Journalists need to avoid it to report fairly, and scientists must be careful not to let it affect their research results. It's crucial for anyone who wants to find the real truth, not just what they want to hear.
Common Mistakes
MISTAKE: Thinking that confirmation bias is always about being stubborn or refusing to change your mind. | CORRECTION: Confirmation bias is often an unconscious process, meaning we don't even realise we're doing it. It's about how our brains naturally filter information.
MISTAKE: Believing that only 'unsmart' people or people with strong opinions have confirmation bias. | CORRECTION: Everyone experiences confirmation bias to some extent, regardless of how intelligent they are or what their beliefs are. It's a fundamental part of human thinking.
MISTAKE: Confusing confirmation bias with simply having a preference for something. | CORRECTION: Confirmation bias isn't just about liking something; it's specifically about actively seeking out or interpreting information in a way that supports an existing belief, while ignoring contradictory evidence.
Practice Questions
Try It Yourself
QUESTION: Your neighbour says that only expensive branded shoes are good. When he buys new shoes, he only reads reviews from people who praise those specific expensive brands. Is this an example of confirmation bias? | ANSWER: Yes, it is an example of confirmation bias.
QUESTION: Your friend believes that eating a certain kind of 'magic fruit' will make them pass exams without studying. They search online and find a forum where one person claims they ate that fruit and got good marks. Your friend ignores all other articles about studying methods. What bias are they showing? | ANSWER: Confirmation bias.
QUESTION: Your school principal wants to know if students prefer online or offline classes. They decide to ask only students who scored very high marks, believing these students are more serious. If these high-scoring students mostly say they prefer offline classes, and the principal uses this to conclude 'all students prefer offline classes,' what thinking error might be happening? Explain why. | ANSWER: Confirmation bias. The principal is only asking a specific group (high-scorers) who might already have a bias towards traditional learning, and then using their answers to confirm a broader belief, ignoring the opinions of other students who might have different preferences.
MCQ
Quick Quiz
Which of these situations best shows confirmation bias?
A student researches all sides of an argument before forming an opinion.

Someone only reads news articles from sources that agree with their political views.
A teacher grades all students' papers fairly, regardless of their personal feelings about the students.

Real World Connection
In the Real World
You see confirmation bias often on social media platforms like WhatsApp or Instagram. People tend to share and believe news or memes that match what they already think, even if the information isn't fully true. This is why it's important to check facts from different sources, not just the ones your friends share.

What to Learn Next
Next, you can learn about 'Critical Thinking' and 'Evaluating Sources'. These concepts will teach you how to actively question information and check its reliability, which is a great way to overcome confirmation bias and think more independently.
