Not Enough
Meaning.
What we filter through is still mostly incomplete. Brains keep filling the gaps with stories — patterns, characters, causes. The biases below are the seams where our storytelling stitches incomplete reality into something that feels whole.
The connectors you should know.

Survivorship Bias
Studying only what survived hides the lessons of what didn't.
Halo Effect
One impressive trait makes us assume the rest is excellent too.
Clustering Illusion
Random patterns look meaningful when we squint hard enough.
Narrative Fallacy
We turn messy data into clean stories — and trust them too much.
Fundamental Attribution Error
We blame users' character; we excuse our own context.
Stereotyping
Group labels stand in for individuals — convenient and wrong.
In-group Bias
We design for people who look, think, and click like us.
Projection Bias
We assume tomorrow's user will want what today's designer wants.
Curse of Knowledge
Once we know something, we can't imagine not knowing it.
False Consensus Effect
We overestimate how much others share our opinions and behaviours.
Dunning-Kruger Effect
Novices overestimate their skill; experts underestimate theirs.
Hindsight Bias
Once we know the outcome, we believe we predicted it all along.
Optimism Bias
We systematically overestimate positive outcomes and underestimate risks to ourselves.
Self-Serving Bias
We credit successes to our skill and failures to bad luck or outside forces.
Gambler's Fallacy
We expect random sequences to self-correct — they don't.
Empathy Gap
We can't accurately predict how we or others will feel in a different emotional state.
Three other ways minds bend.
Too Much
Information
Too Much
Information
There's too much to process. We filter — and the filtering is where bias creeps in.
