Need to
Act Fast.
We rarely have time, attention, or full information. So we choose with confidence we haven't earned, prefer what feels safe, and react more sharply to loss than to gain. Designers shape every nudge along the way.
The decision traps you should know.

Anchoring Bias
The first number we see shapes every number we judge after it.
Loss Aversion
Losing $10 stings more than winning $10 cheers — by about double.
Status Quo Bias
The current setup feels safe even when a better one is one click away.
Sunk-Cost Fallacy
We finish what we started — even when starting over is cheaper.
Effort Justification
We over-value what we built ourselves, however wobbly.
Default Effect
Most users accept the default — make defaults a moral choice.
Decoy Effect
A third, worse option makes the option next to it look brilliant.
Scarcity Effect
Few left, ending soon — pressure cuts deliberation short.
Framing Effect
Same fact, different frame, different decision.
Bandwagon Effect
We adopt beliefs and behaviours because others around us already have.
Hyperbolic Discounting
We prefer a smaller reward now over a larger reward later.
Paradox of Choice
More options feels like freedom but produces paralysis and regret.
Planning Fallacy
We underestimate how long, costly, and risky our plans will be.
Reactance
Tell people they can't have something and they want it more.
Zero-Risk Bias
We prefer eliminating a small risk entirely over significantly reducing a large one.
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.
Not Enough
Meaning
Not Enough
Meaning
Stories, patterns, and confident-sounding causes filling in the gaps.
What Should
We Remember
What Should
We Remember
Memory as reconstruction — peaks, endings, and the odd-one-out.
