ABSTRACT
In previous anchoring studies people were asked to consider an anchor as a possible answer to the target question or were given informative anchors. The authors predicted that basic anchoring effects can occur, whereby uninformative numerical anchors influence a judgment even when people are not asked to compare this number to the target value. Five studies supported these hypotheses: Basic anchoring occurs if people pay sufficient attention to the anchor value; knowledgeable people are less susceptible to basic anchoring effects; anchoring appears to operate unintentionally and nonconsciously in that it is difficult to avoid even when people are forewarned. The possible mechanisms of basic anchoring and the relation between these mechanisms and other processes of judgment and correction are discussed.

Participants in 2 experiments watched a filmed story and then left the lab--with instructions not to think about the film, with instructions to think about the film, or with no instructions. Memories of the film, assessed on participants' return to the lab some 5 hr later, showed reliable effects of thought suppression on memory for the sequence of events in the film. Participants who suppressed thoughts of the film were less able to retrieve the order of events by several measures than were those in the other groups, even thought their retrieval of the events themselves as assessed by recognition, free recall, and cued recall was not generally impaired.
