Core Idea

Blind spot (in psychology) is the failure to see one's own biases and errors while readily seeing them in others. We have a literal blind spot for our own judgment flaws. The core idea: we are bad at self-assessment of bias; assume you have blind spots and use process and others to correct.

Section 2

How to See It

Self & Team
You're seeing Blind Spot when someone can list others' biases in a meeting but doesn't include themselves, or when "we need to be more objective" means "they need to change," not "I might be wrong."
Feedback & Review
You're seeing Blind Spot when performance or strategy reviews focus on others' gaps and the reviewer's own role or bias is left unexamined. The blind spot is invisible to the holder.
Section 3

How to Use It

Assume you have blind spots. Ask: what would I be missing if I were biased here? Use structure: designated devil's advocate, pre-mortems, and feedback from people who don't share your incentives. Invite others to name your possible blind spots and don't punish them for it.
Decision filter
"If we're criticising others' bias or error, have we asked what our own blind spot might be in this situation? Default to 'I might be missing something.'"
As a founder
Build in checks for your own blind spots: a sparring partner, a formal "what am I wrong about?" step in big decisions, and a culture where naming the leader's possible bias is safe and rewarded.
Section 5

Founders & Leaders

Elon MuskCEO, Tesla and SpaceX
Musk has spoken about seeking disconfirming evidence and "first principles" to escape inherited assumptions — a way of compensating for blind spots. Founders can apply this by explicitly asking what they might be missing and by creating process that surfaces their own biases.

Connected Models

Reinforces
Blindspot Bias
Blindspot bias is the belief that we're less biased than others. Blind spot is the inability to see our own biases. Together they explain why we correct others more readily than ourselves — use process to compensate.
Reinforces
Dunning-Kruger Effect
We overestimate our competence in areas where we're weak. Blind spot is the bias version: we don't see our own bias. Both argue for external input and structure to correct self-assessment.
Tension
Introspection Illusion
We think we know our own minds. Introspection illusion says we're wrong about why we think and act. The tension: we can't fully fix blind spots by looking inward; we need outside feedback and process.
Section 8

One Key Quote

"People see the existence and operation of bias in others more readily than in themselves. The blind spot is a meta-bias — we're biased about our own bias."
— Emily Pronin, on the bias blind spot
Section 11

Summary & Further Reading

Blind spot is not seeing our own biases while seeing others'. Counter it by assuming you have blind spots, using process and others to check you, and inviting feedback on your possible bias. Don't rely on introspection alone.
