These category pages track the top-level task groupings from the Wikipedia seed taxonomy, then reframe them for a teaching-first reference site.
Biases here distort numerical judgment, probability, calibration, and first-pass estimation.
What number, rate, sample, or magnitude is being misread because the mind grabbed an easier proxy?
These biases bend choice, commitment, action, avoidance, and preference under uncertainty.
What default, fear, sunk cost, or convenience cue is steering the choice more than the forward-looking case?
Biases in this cluster distort how evidence is interpreted, how rival explanations are tested, and how claims are evaluated.
Is the evidence being used to test the hypothesis, or mainly to protect it?
These biases bend explanations about why events happened and who or what caused them.
What story about cause, blame, or intention feels satisfying here that may be outpacing the evidence?
This group reshapes memory, retrieval, salience, and retrospective interpretation.
Are we remembering the original event, or a later reconstruction that now feels cleaner than reality?
Biases here distort what people say they believe, prefer, remember preferring, or think they observed.
How much of the reported opinion is direct access, and how much is post-hoc reconstruction or self-presentation?
