Q

Direct and indirect routes are key persuasion strategies

A

An individual who carefully evaluates the content of the persuasive message may be approached by the direct route, whereas an individual who is less thoughtful and uses simple cues or stereotypes for evaluating the information may be persuaded through the indirect route.
Direct and indirect processes may act simultaneously and both strategies may be supported through numerous software system features.
