What is an example of the contrast effect?

The decoy price: A $5 small coffee feels cheap next to a $9 large — the large exists mainly to make the others look reasonable.

Where do you see the contrast effect in everyday life?

The decoy price; House hunting; The warm-then-cold water; The B+ that stings; The upsell after the big spend.

Before judging a price or offer, ask 'what is this worth to me on its own?' — not 'compared to what I just saw.'

We judge things by what came right before, not on their own merits. Anything looks better or worse depending on its neighbour.

The decoy price
A $5 small coffee feels cheap next to a $9 large — the large exists mainly to make the others look reasonable.
House hunting
Agents show a dingy place first so the next, ordinary house feels like a gem by contrast.
The warm-then-cold water
Put one hand in hot water, one in cold, then both in lukewarm — it feels hot to one hand and cold to the other.
The B+ that stings
An A-student's B+ disappoints while the same grade thrills a struggling classmate.
The upsell after the big spend
After agreeing to a $30,000 car, a $300 add-on feels trivial by comparison.

Before judging a price or offer, ask 'what is this worth to me on its own?' — not 'compared to what I just saw.'
When a deal looks amazing right after something terrible, suspect the contrast was arranged; reset to absolutes.
Shopping a tiered menu? Notice the extreme option that exists mainly to make its neighbor look reasonable.

That's just how memory works. Lock the contrast effect in with a 5-minute active-recall session — spaced repetition, no signup.

One tap adds it to your review queue — we bring it back right before you'd forget.
