Definition

What is it?

Commission bias is when we prefer to do something (take action) rather than do nothing (stay inactive), even if doing nothing might be a better choice. It's like feeling pressured to act, even when not acting is perfectly fine or even smarter.

Simple Example

Quick Example

Imagine your cricket team is playing, and you are batting. The coach tells you to hit every ball, even if it's a bad ball outside the stumps. You might feel a 'commission bias' to swing your bat and try to hit, even though letting those bad balls go (doing nothing) would be safer for your wicket.

Worked Example

Step-by-Step

Let's say you are playing a mobile game and have 100 coins. You can either use 20 coins to buy a 'mystery box' that might give you a good item or a bad item, or you can save your 100 coins.

1. You feel excited to open the box because your friends always open them. This is the urge to 'do something'.
2. You know there's a 50% chance the box gives you something useless, meaning you lose 20 coins for nothing.
3. If you do nothing, you keep all 100 coins, which is a sure thing.
4. Despite the risk, you buy the mystery box (take action).
5. It turns out to be a useless item.
6. Here, your 'commission bias' led you to act (buy the box) instead of being inactive (saving coins), even though inactivity was the safer bet. You lost 20 coins because of this bias.

Why It Matters

Understanding commission bias helps us make better decisions in daily life and even in big careers. Data scientists and researchers need to be aware of this bias when analysing information, while journalists use it to understand why people react in certain ways. Critical thinking is key in every job, from law to AI.

Common Mistakes

MISTAKE: Thinking commission bias is always about making a bad choice. | CORRECTION: It's about preferring action over inaction. The action might sometimes be good, but the bias is the *preference* for action itself, even when inaction is better.

MISTAKE: Confusing it with 'omission bias' (preferring inaction). | CORRECTION: Commission bias is the opposite – it's about preferring to *do* something. Omission bias is preferring to *not do* something.

MISTAKE: Believing only others fall for commission bias. | CORRECTION: Everyone can experience this bias. Being aware of it in ourselves helps us make more thoughtful choices.

Practice Questions

Try It Yourself

QUESTION: Your parents ask you to choose between two TV shows. One is a new cartoon you've never heard of, the other is your favourite show playing a repeat episode. You pick the new cartoon just because it's 'new' and an 'action'. Is this an example of commission bias? | ANSWER: Yes, it could be. You chose to 'act' (watch something new) rather than 'be inactive' (watch a repeat, which is less 'new action'), even if the repeat might have been more enjoyable.

QUESTION: Your friend suggests trying a new, very spicy street food stall. You usually prefer mild food, but everyone else is trying it. You decide to try the spicy food too. Explain how commission bias might be at play here. | ANSWER: Commission bias is at play because you chose to 'act' (try the spicy food) rather than 'be inactive' (stick to your usual mild food) even though you prefer mild food. The pressure to join in and 'do something new' led to this choice.

QUESTION: A stock market investor has two options: either buy shares in a new, risky company (Option A) or keep their money in a safe bank account earning a small interest (Option B). The investor chooses Option A, even though the risk of losing money is high, because they feel 'they must do something to grow their money'. Identify the bias and explain why it's commission bias. | ANSWER: The bias is commission bias. It's commission bias because the investor chose to 'act' (buy risky shares) over 'being inactive' (keeping money safely in the bank), driven by the feeling that they 'must do something' even when the inactive option might be financially safer.

MCQ

Quick Quiz

Which of these scenarios best shows commission bias?

Choosing to save your pocket money instead of buying a new toy.

Refusing to try a new dish at a restaurant because you prefer your usual order.

Buying a lottery ticket even though the chances of winning are extremely low, because you feel like 'you have to try'.

Deciding to reread your favourite book instead of starting a new one.

The Correct Answer Is:

Option C shows commission bias because the person chooses to 'act' (buy a lottery ticket) even when the outcome is very unlikely to be positive, driven by the urge to 'do something' rather than do nothing. The other options involve choosing inaction or a known preference.

Real World Connection

In the Real World

You see commission bias in advertising all the time! When an app sends you notifications like 'Limited-time offer! Buy now!', it's trying to trigger your commission bias, making you feel you 'must act' and buy something, rather than wait or do nothing. Even online shopping sales use this by creating a sense of urgency.
