Section 1

Core Idea

Blindspot bias is the belief that we are less biased than other people — that we see the world more objectively while others are swayed by bias. We spot bias in others easily and assume we're the exception. The core idea: you are not the exception; assume you're as biased as the next person and build in checks.
Section 2

How to See It

Teams & Culture
You're seeing Blindspot Bias when someone says "we need to avoid groupthink" or "we need to be more objective" and means others, not themselves. The speaker is the implied exception.
Decisions
You're seeing Blindspot Bias when a leader believes their judgment is less affected by incentives, identity, or framing than their team's — and therefore needs less process or challenge.
Section 3

How to Use It

Assume you're biased in the same ways others are. When you notice bias in someone else, ask: how might the same bias apply to me? Use checklists, devil's advocates, and external review for your own decisions. Reward people who point out your possible bias instead of defending your objectivity.
Decision filter
"When we say 'they're biased,' have we asked whether we'd make the same call in their shoes? If we're the only unbiased one in the room, we're probably in blindspot bias."
As a founder
Model "I'm likely biased here too" in key decisions. Create norms where calling out possible bias (including the founder's) is expected and safe. Don't position yourself as the objective arbiter — use process instead.
Section 5

Founders & Leaders

Alex HormoziFounder, Acquisition.com; author, $100M Offers
Hormozi stresses tracking outcomes and proof over self-assessment. Founders can apply this by not trusting their own "I'm objective" — use data, process, and outside challenge so blindspot bias doesn't protect your ego at the cost of better decisions.
Section 7

Connected Models

Reinforces
Blind Spot
Blind spot is not seeing our own biases; blindspot bias is believing we're less biased than others. Together they mean we under-correct ourselves. Use process and feedback to compensate for both.
Reinforces
Dunning-Kruger Effect
We overestimate our ability in weak areas. Blindspot bias is the bias version: we overestimate our objectivity. Both suggest humility and external calibration.
Tension
Overconfidence
We're overconfident in our judgment. Blindspot bias adds "and we're less biased." The tension: reduce both by requiring evidence and process instead of trusting self-assessment of objectivity.
Section 8

One Key Quote

"The first principle is that you must not fool yourself — and you are the easiest person to fool."
— Thomas Gilovich
Section 11

Summary & Further Reading

Blindspot bias is believing we're less biased than others. Counter it by assuming you're as biased as anyone, using process and challenge for your decisions, and rewarding people who point out your possible bias. Don't be the exception.
