“A person’s established beliefs are often difficult to change and resist contradictory evidence (Ross, Lepper & Hubbard, 1975). This phenomenon, referred to as “confirmation bias”, can have especially detrimental effects when working with child witnesses. If an interviewer enters a room, prepared to question a child, and brings along pre-established beliefs about the case or the accuracy and credibility of the child, the interviewer may unintentionally put disproportional weight on some statements the child makes while ignoring others. If the interviewer’s initial suspicions are incorrect, this could create a false report. Confirmation bias is potentially a problem for all people who may interact with a child witness, even professionals in the field of forensics, human development and social science. In fact, experts tend to be more confident in their evaluations of witnesses than others, despite not necessarily being more skilled at distinguishing accurate from inaccurate statements (DePaulo et al., 2003; Wessel, Drevland, Eilertsen, & Magnussen, 2006).” “A person’s established beliefs are often difficult to change and resist contradictory evidence (Ross, Lepper & Hubbard, 1975).
