Watch for
Identifying others biases while assuming you are objective.

Bias Blind Spot
We see bias in others but not ourselves.
The tendency to recognise cognitive biases and logical fallacies in other people while failing to notice them in oneself.
Why it matters: One of the most meta biases. If you think you are not biased you are probably exhibiting the bias blind spot.
Try this
Assume you are equally susceptible to the biases you see in others.
Real-world example
A person easily spots confirmation bias in their political opponents but cannot see it in their own reasoning.

Psychological mechanism
Introspection illusion. We assess our own biases by looking inward at our conscious thoughts and intentions which feel unbiased. We assess others biases by observing their behaviour which reveals bias. This difference in data sources creates the asymmetry.

Below is a realistic scenario. Read it, then choose what you would do. The feedback will show whether a cognitive bias influenced your choice — not to judge, but to reveal the pattern in action.
Thought Experiment
This experiment places you in a realistic decision. Your instinctive choice will reveal whether bias is at work.

Debrief
The bias blind spot is the most meta of all biases. It is the reason reading lists of biases is not enough — we apply them to others immediately but not to ourselves. The corrective is to assume you are as biased as the people you judge.
