Anchoring & Adjustment
The Anchor Effect
How an irrelevant number shapes your estimate
~60 secTversky & Kahneman (1974)
You will be shown a random number, then asked to estimate an unrelated quantity. The experiment tests whether that initial number — the "anchor" — influences your response.
Before we begin
You will be briefly shown a number. This number is randomly generated and has no relation to the question you will answer next.
Nevertheless, research consistently shows that this irrelevant anchor shifts estimates by 10–25%. Try to ignore it — but be honest with your first instinct.
