Source characteristics = characteristics of the person who delivers the message, including the person's..

1) Attractiveness

Attractive spokespeople are more persuasive, even for topics completely unrelated to attractiveness.

Effects of attractiveness are through the peripheral route: attractive people are rated more favorably, and those favorable feelings become associated with the message
