This quiz illustrates common cognitive biases through everyday scenarios. It is for educational and self-reflection purposes only. Everyone is susceptible to cognitive biases — awareness is the first step to better decision-making.
A cognitive bias is a systematic error in thinking that affects the decisions and judgments we make. Our brains are wired for speed, using mental shortcuts that served our ancestors well — but in the modern world, these shortcuts can lead to poor reasoning, bad decisions, and distorted perceptions. This quiz uses real-world scenarios to show you exactly which biases affect your thinking.

How to Use the Cognitive Bias Quiz
The cognitive bias quiz uses scenario-based questions to reveal your susceptibility to 18 common thinking errors. Unlike abstract definitions, this quiz puts you inside real situations — a shopping decision, a workplace dilemma, a social interaction — and shows you exactly where your reasoning diverges from rational thinking.
Step 1: Read Each Scenario Carefully
Each scenario describes a situation that most people encounter in daily life. Read it fully, then choose the response that feels most natural or compelling to you — not what you think is the "right" answer. The quiz is most useful when you answer honestly.
Step 2: Choose Your Response
Each scenario has 3-4 response options. One reflects a specific cognitive bias; the others represent more neutral or rational choices. Your natural reaction is the data — there are no trick questions, only honest self-assessment.
Step 3: Flip the Reveal Card
After each answer, a flip card appears. Tap it to reveal which cognitive bias was embedded in the scenario, along with a 2-sentence explanation. If you avoided the bias — great. If you fell for it — even better, because now you know where your blind spot is.
Step 4: Review Your Results
After all 18 scenarios, your results show a full breakdown by bias — green for biases you resisted, orange for ones that caught you. This gives you a personalized map of your cognitive vulnerabilities.
The 12 Biases Covered
Anchoring Bias: Over-relying on the first piece of information encountered. Confirmation Bias: Seeking information that confirms existing beliefs. Sunk Cost Fallacy: Continuing because of past investment rather than future value. Availability Heuristic: Judging likelihood by how easily examples come to mind. Bandwagon Effect: Adopting beliefs because many others hold them. Framing Effect: Being influenced by how information is presented rather than its content. Loss Aversion: Feeling losses more intensely than equivalent gains. Halo Effect: Letting one positive trait color overall judgment. Status Quo Bias: Preferring the current state of affairs over change. Dunning-Kruger Effect: Overestimating competence in areas of low knowledge. In-group Bias: Favoring members of your own group. Optimism Bias: Overestimating positive outcomes for yourself.

How does the cognitive bias quiz work?
Each question presents a real-world scenario. You choose the most appealing response. After each answer, a flip card reveals which cognitive bias was at play and explains the psychology behind it.
What is a cognitive bias?
A cognitive bias is a systematic pattern of deviation from rational thinking. Our brains use mental shortcuts (heuristics) to make fast decisions, but these shortcuts sometimes lead us astray — causing us to misremember facts, misjudge risks, or make poor choices.
What is anchoring bias?
Anchoring bias occurs when we rely too heavily on the first piece of information we encounter. For example, if a product is marked 'was $200, now $80,' the $200 anchor makes $80 feel like a bargain — even if $80 is still overpriced.
What is the sunk cost fallacy?
The sunk cost fallacy is continuing a behavior because of previously invested resources (time, money, effort) rather than future value. Finishing a bad movie because you paid for it, or staying in a failing project because of past investment, are classic examples.
Can I reduce my cognitive biases?
Yes. Awareness is the crucial first step — you cannot correct a bias you do not recognize. Other strategies include slowing down fast thinking, seeking disconfirming evidence, consulting people with different perspectives, and using structured decision frameworks.
Are cognitive biases always harmful?
Not always. Many biases evolved as useful mental shortcuts that help us make quick decisions with limited information. They become problematic when applied in contexts where careful reasoning is needed — major financial decisions, medical choices, or evaluating complex situations.
