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.

Founders & Leaders

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.

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.

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.

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.
