Why alarm outruns the fact that would settle it
Panic spreads through networks faster than the correction that would calm it, so by the time the facts arrive the damage from the fear is already done.

Intuition test — answer before you read on
Why does market panic typically precede the facts that could settle it?
Correct answer: A
Option B invents a profit motive for exchanges. Option C ignores false alarms. Option A identifies the structural speed asymmetry: alarm is light and travels fast; correction is heavy and arrives late.
A rumour of insolvency spread through social channels in minutes, and sellers hit the market before any verification was possible. Hours later the protocol posted proof of reserves — the alarm was baseless — but the price had already cratered and the liquidity had fled. The correction arrived factually intact and temporally irrelevant. Panic travels at the speed of emotion; correction travels at the speed of evidence, and the gap between the two is where the damage lives.
What everyone sees
A holder sees the price collapsing and reads genuine danger: the market is selling hard, so something must be very wrong. The crowd’s action becomes evidence. The holder sells to protect himself, joining the cascade, and by the time the reassuring fact is published, his position is already gone at a loss. He reacted to the alarm’s speed, not its accuracy.
What is actually happening
Research on information cascades and panic shows that negative signals propagate faster than their corrections because alarm requires no evidence while correction requires proof. The asymmetry is structural: fear is shared on impulse, while debunking must first be produced and then believed. Markets react to the first-mover signal, and the correction that follows must overcome both the lag and the damage already done.
Why it stays hidden
The hidden mechanism is a speed asymmetry between alarm and evidence. Panic travels light — a sentence, a screenshot, a forwarded message — while correction is heavy, requiring verified data and a sceptical audience. The holder acts on whichever arrives first, and alarm always does. By the time the fact catches up, the sell-off has already converted rumour into real losses.
Panic is fast because it needs no proof. Correction is slow because it does. The damage lives in the gap between the two.
Panic is fast because it needs no proof. Correction is slow because it does. The damage lives in the gap between the two.
