In the peripheral route to persuasion, people pay attention to incidental or superficial aspects of the message. They use this route when they have little motivation (for example, the issue has no bearing on their personal outcomes) or little ability to attend to its deeper meaning (for example, they have little knowledge or are distracted). With this route, people are persuaded by easy-to-process cues, such as the attractiveness and credibility of the message source or the mere length of the persuasive message.
