A real financial moment, a familiar mental trap.Can you name it?
Sign in to unlock Level 8.
Sign inThis Lab shows a real financial moment and asks which bias is at work. You choose from three names, and the Lab then reveals the bias, a plain example from outside money, and a question to ask yourself. The eight biases come from the Maetis Wisdom Vault. There is no score: the guess exists to give you a moment of commitment before the reveal, and the reveal is the same whichever name you pick.
How to use this Lab

- Choose Try another to move to the next of the eight. If you are signed in and have played before, the Lab shows what you guessed last time.
What to notice
- Naming a bias is a skill
- The eight biases are confirmation bias, anchoring, overconfidence, recency bias, loss aversion, herd mentality, the sunk cost fallacy and hindsight bias. Several look alike from the outside, which is why choosing between them is useful practice.
- The same pattern shows up outside money
- Each reveal includes an everyday example from outside finance. Seeing the pattern in a familiar setting makes it easier to spot in a financial one.
- The question matters more than the label
- Each card ends with a question to ask yourself. The aim is not to win the guess. It is to build the habit of asking the question when it counts.
How a card unfolds (hypothetical)
You read a situation in which someone sticks with a poor investment because of how much they have already put in. You guess among three names, and the Lab reveals that this is the sunk cost fallacy: past money that cannot be recovered is treated as a reason to keep going. It shows an example from outside money, such as finishing a meal you no longer enjoy because you paid for it, and asks what you would decide if you were starting today.
What this Lab does not show
- Eight biases are a small sample of how judgement bends, and a real moment often involves several at once.
- Naming a bias does not remove it. The Lab is practice for noticing, not a cure.
- If you are signed in, your guesses are saved to your account so the Lab can show your last guess. Deleting your account removes them. Signed out, nothing is saved.
- It does not tell you what to buy or sell. Maetis does not give investment advice.
Common questions
- What is a cognitive bias in investing?
- A familiar mental shortcut that bends judgement, such as weighting recent events too heavily or only noticing evidence that agrees with you.
- Which biases does the Lab cover?
- Confirmation bias, anchoring, overconfidence, recency bias, loss aversion, herd mentality, the sunk cost fallacy and hindsight bias.
- Is there a score?
- No. The guess is there to create a moment of commitment before the reveal, and the reveal is the same whichever you pick.
- Can I get rid of a bias by learning its name?
- Not by itself. Knowing the name helps you notice the pattern, and the question on each card helps you pause before you act.
