How a First Number Shapes an Estimate

Written by Studio AM.

When we judge an unknown quantity, the mind reaches for a starting point and adjusts from there. The trouble is that the starting point need not be relevant, and the adjustment is usually too small. A figure we encounter, even an arbitrary one, can pull our estimate toward itself. Psychologists call this the anchoring effect.

The pull is surprisingly strong. In studies, people asked whether a quantity is higher or lower than some random number, perhaps drawn from a spin of a wheel, often give later estimates that drift toward that number. They do not believe the wheel knows anything, and yet their guesses bend toward it. An anchor can influence an estimate even when we are told to ignore it.

This quietly shapes the marketplace. A high original price printed beside a sale price makes the sale feel generous, because the original anchors our sense of what the item is worth. A first offer in a negotiation can influence later counteroffers. That may give the first speaker an advantage, although an offer can also reveal information the other person uses against them. The outcome depends on more than who speaks first.

Rather than assume you are immune, ask deliberately what evidence supports an estimate. Comparing market prices or preparing a target before a discussion gives you another basis for judgment. These steps can help challenge an anchor, although they do not guarantee an unbiased decision.
