When we look at a price, we also look — quietly, in memory — at prices we've seen before. Because those reference prices are personal memories, not objective data, two people can look at the same price tag and feel entirely different things.

Three memories that do the heavy lifting

1) Your first purchase price. Whatever you first paid becomes a lifetime anchor. If you bought an apartment in Seoul for 200M won 20 years ago, 1.2B feels outrageous. To someone who just bought at 1.5B, 1.2B looks like a bargain.

2) The peak price you remember. The highest figure you ever saw stays in memory for years. If your first Bitcoin view was $70,000, $40,000 feels cheap. If your first view was $16,000, $40,000 feels dangerous. Same price, different interpretations.

3) The lowest price you remember. Cheap memories breed the fantasy that the number "might come back." In a world with structural inflation, most prices don't return to past lows — and that fantasy routinely wrecks timing decisions.

Loss aversion warps memory

A classic behavioral-economics finding: people feel a loss roughly twice as strongly as a gain of equal size. Your purchase price therefore acts like gravity in memory — going below it hurts a lot; going above it doesn't feel as good as you'd expect.

That asymmetry bleeds into decisions. Waiting for "break-even" can miss better opportunities; locking in small gains too quickly can leave long compounding on the table.

The peak-end effect

Memory compresses a period into its peak and its ending. Ask someone about their 2020 portfolio and they'll remember the March crash and the year-end recovery vividly; the grinding middle fades. The problem: that compressed memory becomes the premise for the next decision.

Auditing your price memory

Asking where a memory came from already shifts its power.

• What reference point makes this price feel "cheap" or "expensive"?
• Did that reference come from a purchase, a headline, or a friend?
• How much have inflation, FX, and taxes moved since then?
• Is today's decision protecting the old reference, or serving a future plan?

How PriceGuess plays into this

Repeating the same assets in Chart Quiz and Higher or Lower slowly rewrites your memory. That's the training effect. Over time the "first impression" loses weight and a sense of range takes its place.
