The present research examined the social context of information acquisition. The main purpose was to examine how decision‐makers' information acquisition processes changed when they were provided access to expert advice. Results indicated that all decision‐makers opted to acquire advice; however, they typically did so only after completing over 75% of their own information search. Decision‐makers agreed more with the advice as task complexity increased, but, in general, searched information in two stages—i.e., a pre‐advice “hypothesis generation” stage and a post‐advice “hypothesis testing” stage. To behave in an adaptive manner, decision‐makers could have used expert advice either to increase their decision accuracy or to reduce their effort expenditure (or both); they chose the former. Implications and further extensions are discussed. Copyright © 2006 John Wiley & Sons, Ltd.
