Definition

What is it?

Confirmation bias is when we look for, remember, and favour information that supports what we already believe or want to believe. It's like having a favourite team and only noticing news that says they are the best, ignoring anything negative.

Simple Example

Quick Example

Imagine you believe your friend, Rohan, is very good at cricket. During a match, Rohan takes a brilliant catch. You immediately think, 'See, I knew he was great!' But you might forget the two times he dropped easy catches earlier. This is confirmation bias.

Worked Example

Step-by-Step

Let's say a student, Priya, thinks that studying only on Sunday nights helps her get good marks.

1. Priya studies hard on Sunday night for her Maths test.
---2. She gets a good score on the Maths test.
---3. Priya tells herself, 'See, Sunday night study works best for me!'
---4. She ignores that she also studied a little on Saturday and revised on Monday morning, which also helped.
---5. She also forgets the time she studied only on Sunday night and still got an average score.
---6. Because she focused only on the times Sunday study worked, she confirms her belief.

ANSWER: Priya's belief that only Sunday night study works is strengthened because she selectively remembers successes and ignores other factors or failures.

Why It Matters

Understanding confirmation bias is crucial for jobs like a journalist, who needs to report fair news, or a data scientist, who must analyse information without personal opinions. It helps us make better, unbiased decisions in research and law, ensuring fairness for everyone.

Common Mistakes

MISTAKE: Thinking that having a strong opinion is the same as confirmation bias. | CORRECTION: Confirmation bias is not just having an opinion, but actively seeking out and only remembering facts that agree with your opinion, while ignoring facts that don't.

MISTAKE: Believing that confirmation bias only affects 'other' people and not themselves. | CORRECTION: Everyone, including you, can fall victim to confirmation bias. It's a natural human tendency, so we need to be aware of it in ourselves.

MISTAKE: Confusing confirmation bias with simply being right. | CORRECTION: You might be right about something, but if you only looked for information that supported your view and ignored everything else, you still showed confirmation bias in how you reached that conclusion.

Practice Questions

Try It Yourself

QUESTION: Your sister believes that eating chocolate makes her happy. When she feels sad and eats chocolate, she feels better. What might she be forgetting? | ANSWER: She might be forgetting other times she felt sad and ate chocolate but didn't feel much better, or times she felt better without eating chocolate.

QUESTION: A news channel only shows stories that support a particular political party. What kind of bias are they showing? Why is this a problem? | ANSWER: They are showing confirmation bias. This is a problem because viewers will only get one side of the story and might not make informed decisions.

QUESTION: Your friend believes that a new mobile game is the best ever. He tells you about all the amazing features and how much fun he's having. What would you ask him to help him think more critically about his belief? | ANSWER: You could ask him, 'What are some things you don't like about the game?' or 'Have you tried other new games to compare it with?' This encourages him to look for different types of information.

Real World Connection

In the Real World

In India, during election times, people often follow social media pages or news channels that only support their preferred political party. They might share posts that confirm their views and dismiss any opposing arguments as 'fake news.' This can also happen when buying a new phone; you might only look at reviews that praise the brand you already like.
