ANCHORING, FAMILIARITY, AND CONFIDENCE IN THE DETECTION OF DECEPTION

Anchoring in judgments is the tendency for the final judgment to be bi ased toward the initial estimate through insufficient adjustment. In t he context of the detection of deception, it has been used to explain phenomena such as negative absolute leakage and the truthfulness bias. We examined the influence of order of judgment type on attitude ratin gs, accuracy, and the truthfulness bias. Receivers of communications s hould tend to anchor their judgments on the sender's attitudinal posit ion if asked to make attitude judgments first and on the sender's beha vior if asked to make truthfulness judgments first. The results partly support these predictions. Negative absolute leakage, accuracy, and t he truthfulness bias were not significantly different for those who ma de attitude judgments before truthfulness judgments. However, results show that accuracy decreased as the session continued and there was no difference in the confidence with which truth and deception judgments were made, but there was a positive relation between confidence and t ruthfulness bias.
