anchoring effect

Anchoring is a cognitive bias that describes the common human tendency to rely too heavily on the first piece of information offered (the “anchor”) when making decisions. During decision making, anchoring occurs when individuals use an initial piece of information to make subsequent judgments. Once an anchor is set, other judgments are made by adjusting away from that anchor, and there is a bias toward interpreting other information around the anchor. For example, the initial price offered for a used car sets the standard for the rest of the negotiations, so that prices lower than the initial price seem more reasonable even if they are still higher than what the car is really worth.

In past issues of Negotiation, we’ve reviewed the anchoring effect – the tendency for negotiators to be overly influenced by the other side’s opening bid, however arbitrary. When your opponent makes an inappropriate bid on your house, you’re nonetheless likely to begin searching for data that confirms the anchor’s viability. This testing is likely to affect your judgment – to the other party’s advantage.

Psychologists Amos Tversky and Daniel Kahneman identified the anchoring effect in 1974. Participants watched a roulette wheel that, unknown to them, was rigged to stop at either 10 or 65, the estimated the number of African countries belonging to the United Nations. For half of the participants, the roulette wheel stopped on 10. They gave a median estimate of 25 countries. For the other half, the wheel stopped on 65. Their median estimate was 45 countries. The random anchors dramatically affected judgment.

Conflict Management – Evenhanded Decision Making

As discussed in past articles, anchoring and framing can bias important decisions in negotiation. A buyer may make a more generous offer than she intended, for example, after a seller drops anchor on a bold demand. A litigant who focuses on his chances of winning in court – a positive frame – may be less likely to settle than if he concentrated on a negative frame: his corresponding chances of losing.

Many researchers have studied how such biases are amplified or moderated by mood, expertise, and personality. Groundbreaking work by professors John D. Jasper and Stephen D. Christman of University of Toledo now suggests that our susceptibility to decision biases is hardwired.
