Start with the quick check
Use the entry question or snapshot to decide whether the label is even live before reading the rest of the page into the situation.
About
A field guide to recurring errors in judgment
CogBias is built for readers who want more than a list of names. It combines definitions, comparisons, practice tools, theory pieces, and teaching materials so a bias label can lead to a better question or a better procedure.
What the site is for
Use CogBias when you need to spot a distortion, compare nearby labels, teach the difference, or change a workflow that keeps reproducing the same kind of judgment error.
Best ways to begin
- Start with a context hub if you know the setting but not the label.
- Use comparison guides when two nearby biases seem plausible.
- Use learning paths when you want a guided route instead of a full index.
- Use self-checks and assessment when you want practice rather than explanation alone.
How the site is organized
Different parts of the site do different jobs, so readers can move from identification to comparison to practice without losing the thread.
Bias pages
Each entry aims to do four things well: define the bias, show what it feels like from inside, distinguish it from close neighbors, and offer a better process.
Contexts and comparisons
Context hubs group biases by real settings such as news reading, meetings, teaching, relationships, and product work. Comparison guides slow down the most common nearby-label confusions.
Practice tools
Self-checks, assessment sets, countermoves, and teaching kits are there to change what people actually do, not just what they can define.
Theory and optional AI prompts
Theory pages explain the deeper structure behind the labels. The AI prompt kits are optional add-ons for readers who want help widening the frame after the case is already concrete.
How to read a bias page
The strongest way to use the site is to move from recognition to contrast to repair.
Look at the illustration and examples
The posters and examples are there to make the hidden pull visible in ordinary situations, not just in textbook definitions.
Compare close neighbors
Nearby confusions usually matter more than isolated definitions. If two labels feel plausible, stop and compare them directly.
End with a process move
The goal is not just to name the bias. It is to change the question, sequence, default, room structure, or review habit that keeps reproducing it.
