Prior perceived uncertainty and information system reports interact to reduce uncertainty, which increases system use. Perceived uncertainty includes three components: state of nature, available alternatives, and outcomes. Computer based information systems are classified into three types that differentially describe each component: data systems indicate the state of nature; forecasting systems indicate likely outcomes; and suggestion systems indicated alternatives that will likely lead to desirable outcomes. Decision makers highly uncertain about one component should become less uncertain when they receive reports about that component from the corresponding information system type. The decreased uncertainty should lead the decision makers to increase their information system use, both increasing their beliefs in their own performance and reducing their tendencies to avoid decisions. |
