Definition
What is it?
Confirmation bias is our tendency to look for, interpret, and remember information in a way that confirms our existing beliefs or ideas. It means we often pay more attention to things that agree with what we already think, and ignore things that don't.
Simple Example
Quick Example
Imagine you believe that eating samosas every day makes you super smart. You might start noticing news articles about smart people who also love samosas, and forget about all the smart people who don't eat them. This is confirmation bias in action.
Worked Example
Step-by-Step
Let's say Riya believes that her favourite cricket team, the 'Mumbai Blasters', always performs better when she wears her lucky blue jersey.
---
Step 1: Riya watches a match where the Mumbai Blasters win, and she is wearing her blue jersey. She thinks, 'See, my blue jersey works!'
---
Step 2: The next week, the Mumbai Blasters lose, and Riya was wearing a different shirt. She might think, 'Oh, I should have worn my blue jersey.'
---
Step 3: A few matches later, the Mumbai Blasters win, but Riya was NOT wearing her blue jersey. She might not pay much attention to this match, or quickly forget it.
---
Step 4: When the Mumbai Blasters lose, even if Riya IS wearing her blue jersey, she might find another reason for the loss (e.g., 'the umpire was unfair').
---
Answer: Riya is selectively noticing wins with her blue jersey and finding excuses for losses or ignoring wins without it, reinforcing her original belief about the jersey's luck.
Why It Matters
Understanding confirmation bias is crucial in fields like journalism, law, and social sciences. Journalists need to avoid it to report fair news, lawyers must be aware of it to evaluate evidence objectively, and social scientists use it to study human decision-making. It helps people make better, more balanced decisions in their careers and daily lives.
Common Mistakes
MISTAKE: Thinking confirmation bias means someone is intentionally lying or being stubborn. | CORRECTION: Confirmation bias is often an unconscious mental shortcut; people aren't usually aware they are doing it.
MISTAKE: Believing that only 'unintelligent' people experience confirmation bias. | CORRECTION: Everyone, regardless of intelligence, can fall victim to confirmation bias because it's a natural human tendency.
MISTAKE: Confusing confirmation bias with simply having a strong opinion. | CORRECTION: Having a strong opinion is fine, but confirmation bias is specifically about how you seek and interpret information to support that opinion, often ignoring contradictory evidence.
Practice Questions
Try It Yourself

QUESTION: A student thinks they are bad at Maths. When they solve a problem correctly, they think it was 'luck'. When they get one wrong, they say, 'See, I told you I'm bad at Maths!' Explain how confirmation bias is at play here. | ANSWER: The student focuses on mistakes as proof of their belief and dismisses successes as luck, confirming their existing negative self-belief about Maths.
QUESTION: Your family always buys a specific brand of atta (flour). One day, a neighbour tells them another brand is better and cheaper. Your family ignores this and only talks about how their usual brand makes the softest rotis. What is happening, and what could they do to overcome it? | ANSWER: Confirmation bias is happening because they are focusing on the positive aspects of their current brand and ignoring new information. To overcome it, they could try buying a small pack of the new brand and comparing it fairly, or read unbiased reviews online.
