Confirmation Bias

I tell you that “2–4–6” follows a rule. Would you try “8–10–12,” or a sequence that could defeat your first idea?

PANEL A // CORE

The essential idea

When testing a hypothesis, we often choose examples expected to work if it is true. The problem is that those examples may fit rival explanations too. More informative tests distinguish alternatives and risk proving our first intuition wrong.

PANEL B // SEQUENCE

How it works

  1. 01

    You form an initial explanation from the information available.

  2. 02

    You seek or interpret examples that fit it.

  3. 03

    Without a strong rival test, you overestimate how much the evidence supports it.

PANEL C // CASE

Concrete case

If you think music improves your memory, you may recall successful study sessions with music. A real comparison also tracks silent sessions, task difficulty, and sleep.

PANEL D // LIMIT

It does not mean this

Evidence that agrees with a belief is not automatically invalid; what matters is how it was sought, interpreted, and compared.

RHO // FIELD NOTE

Take it with you

Before searching, write down what result would change your mind and test a rival explanation.

FINAL PANEL // APPLY
