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.
