Definition
What is it?
Confirmation bias is when we look for information that supports what we already believe and ignore information that goes against it. It means we prefer to agree with ourselves, even if it's not the full truth.
Simple Example
Quick Example
Imagine you believe your favourite cricket team, the Mumbai Indians, is the best. If someone shows you their past winning records, you'll pay close attention. But if they show you their losing streaks, you might quickly dismiss it or say, 'Oh, that was just a bad day.'
Worked Example
Step-by-Step
Let's say you believe that eating samosas every day makes you smart. --- Step 1: You read an article online about how 'spicy food boosts brain power.' You immediately think, 'See, I told you samosas are good for me!' --- Step 2: You ignore another article that says 'eating too much fried food is unhealthy.' You might think, 'That's not about samosas specifically,' or 'My grandmother eats fried food and she's smart.' --- Step 3: You share the 'spicy food boosts brain power' article with your friends as 'proof.' You don't mention the other article. --- Step 4: Your belief that samosas make you smart gets stronger because you only focused on the information that agreed with you. You didn't consider all the facts.
Why It Matters
Understanding confirmation bias helps you make better decisions in life and in future careers. In fields like Data Science and Research, people need to look at all data fairly, not just what supports their initial ideas. Even journalists need to avoid it to report true stories.
Common Mistakes
MISTAKE: Only reading news articles or watching videos from sources you already agree with. | CORRECTION: Try to get information from different sources, even those with different viewpoints, to get a complete picture.
MISTAKE: Believing something is true just because your friends or family believe it, without checking facts yourself. | CORRECTION: Always question and verify information, even if it comes from people you trust. Do your own research.
MISTAKE: Dismissing new information instantly if it challenges your existing belief, without giving it a fair chance. | CORRECTION: Pause and consider new information. Ask yourself why it might be true, even if it feels uncomfortable at first.
Practice Questions
Try It Yourself
QUESTION: Your friend says, 'All mangoes are sweet.' You only remember the sweet ones you've eaten. Is this an example of confirmation bias? | ANSWER: Yes, because you are only focusing on the mangoes that support your friend's statement and ignoring any sour ones you might have tasted.
QUESTION: A student thinks online classes are less effective than offline classes. They share only examples of internet connection issues during online classes and ignore successful online lessons. What bias are they showing? | ANSWER: Confirmation bias.
QUESTION: You believe a new mobile game is the best. You spend hours watching videos of players winning in that game. Your friend tells you about bugs and glitches they faced, but you say, 'That's just a one-off.' Explain how confirmation bias is at play here. | ANSWER: You are showing confirmation bias by actively seeking out positive examples (winning videos) that confirm your belief the game is best, and dismissing negative information (bugs/glitches) that goes against your belief as 'one-off' without truly considering it.

Real World Connection
In the Real World
Confirmation bias can be seen in how people choose news on social media. If you always click on news headlines that agree with your political views, platforms like Facebook or X (formerly Twitter) will show you more of that content, strengthening your existing beliefs and creating an 'echo chamber.'
