Blind-Spot Bias
Bias Summary: Assume you are less biased than others.
People detect cognitive errors in peers yet deny their own susceptibility, limiting self-correction. Research context: Cognitive-psychology research treats biases as predictable shortcuts that can be useful under time pressure but can also systematically distort judgment. The distortion grows when evidence is ambiguous, emotionally charged, or aligned with prior beliefs. Pattern-specific focus: Assume you are less biased than others. Practical review method: separate factual claims from interpretation, check source quality, and test whether the conclusion survives alternative explanations.

How to recognize blind-spot bias yourself
- One-sided evidence selection while conflicting evidence is minimized.
- Probability judgments based on vivid anecdotes instead of base-rate data.
- Confidence level that is higher than the quality of available evidence.
- Identity, loyalty, or prior commitment treated as evidence.
Verification questions
- What disconfirming evidence would change this conclusion, and is it shown?
- Are estimates grounded in representative data or in memorable examples?
- Would the same reasoning be accepted if group identity or prior beliefs were reversed?
