Objective To investigate how people's sequential adjustments to their position are impacted by the source of the information. Background There is an extensive body of research on how the order in which new information is received affects people's final views and decisions as well as research on how they adjust their views in light of new information. Method Seventy college-aged students, 60% of whom were women, completed one of eight different randomly distributed booklets prepared to create the eight different between-subjects treatment conditions created by crossing the two levels of information source with the four level of order conditions. Based on the information provided, participants estimated the probability of an attack, the dependent measure. Results Confirming information from an expert intelligence officer significantly increased the attack probability from the initial position more than confirming information from a longtime friend. Conversely, disconfirming information from a longtime friend decreased the attack probability significantly more than the same information from an intelligence officer. Conclusion It was confirmed that confirming and disconfirming evidence were differentially affected depending on information source, either an expert or a close friend. The difference appears to be due to the existence of two kinds of trust: cognitive-based imbued to an expert and affective-based imbued to a close friend. Application Purveyors of information need to understand that it is not only the content of a message that counts but that other forces are at work such as the order in which information is received and characteristics of the information source. |
