Persuasion affects the feeling of Certainty.[1]
Daniel O'Keefe defines persuasion as "A successful intentional effort at influencing another's mental state through communication in a circumstance in which the persuadee has some measure of freedom."[2]
All persuasion is self-persuasion because the only one that can convince someone of something is themselves. The internal dialog is the most important. External forces to persuade someone is most often just showing that change is possible.[3]
