Bias Map

Where biases sit by visibility and temptation.

This map plots entries with both teaching-gauge estimates. The horizontal axis asks how easy the bias is to spot from the outside; the vertical axis asks how easy it is to innocently commit. Colors follow the site’s category layer.

How to read the upper-left

High vertical and low horizontal scores mark biases that are easy to fall into but harder for outsiders to notice. These often need process checks before the judgment hardens.

How to read the upper-right

High scores on both axes mark familiar traps: people may recognize them in others and still slip into them without a deliberate countermeasure.
