Cognitive Biases

CogBias

A practical cognitive-bias site with clear definitions, learning paths, assessments, self-audits, and debiasing tools.

Assessment

A mixed scenario test of what is bending the judgment and what would interrupt it best

Each run draws from a bank of short bias scenarios. For every item, choose the bias that most likely explains the drift and then choose the best next move for improving the process. You can now run the bank by difficulty, bias category, and applied context instead of taking one undifferentiated quiz.

What it is for

Use this for classroom comparison, self-calibration, or team practice when you want something more demanding than a definition quiz. The second answer matters as much as the first.

How it differs from self-checks

Self-checks are preventive field tools. This page is a mixed assessment built for diagnosis plus repair: name the likely pressure, then choose the best intervention.

Foundational

Clearer first-pass cases for learning the major families and repair moves.

30 scenarios

Applied

Messier real-world cases where the right label and the right repair can come apart.

35 scenarios

Advanced

Meta-bias, overlap, and interpretation-heavy scenarios for stronger readers and classrooms.

10 scenarios

Practice by context

These modes pull scenarios from the domain hubs, so a teacher, facilitator, product team, or media-literacy group can practice with examples closer to their actual work.

Take the mixed scenario assessment

Each set uses real decision, forecasting, conflict, and meeting situations rather than bare definitions.
