Abstract

As a first attempt to empirically investigate the scope of external information-seeking under uncertainty, this paper examines the direct and interactive effects of task uncertainty on the scope of external information-seeking. Search depth and breadth are the two components of the scope of external information-seeking in defining an individual's external information search strategy. The empirical results show that at the source portfolio level, task uncertainty exhibits positive effects on both the depth and breadth of external information-seeking. It is also found that there is a positive relationship between task uncertainty and depth-first propensity, which is defined as a seeker's propensity to acquire information through increasing search depth instead of through widening search breadth at the source portfolio level. Furthermore, the results show that the positive relationship between task uncertainty and depth-first propensity in external information-seeking is stronger when perceived source accessibility is low than when it is high. This study makes a contribution to the information-seeking literature by helping us understand how task uncertainty and source characteristics shape an individual's external information-seeking at the level of source portfolio and providing evidence of the task-source fit perspective in explaining information-seeking behaviour under uncertainty at the source portfolio level.
