| Abstract: | This paper discusses the social context of information acquisition, and it examines how decision-makers' information acquisition processess changed when they were provided access to expert advice. It is shown that all decision-makers opted to acquire advice typically only after completing over 75% of their own information search. They agreed more with the advice as task complexity increased, but, in general, searched information in two stages - a pre-advice "hypothesis generation" stage and a post-advice "hypothesis testing" stage. Decision-makers chose to use expert advice to increase their decision accuracy rather than to reduce their effort expenditure. |
