Persuasion

Persuasion is in short social influence. Typically used to get someone to believe or follow a certain action. For example, if someone has an opposite opinion on a matter, persuasion can be used to change ones mind. The use of good reasoning and power in speech are significant components of persuasion.
Persuasion is used in the example of the New York Times article on debt, "U.S. is in any imminent danger of turning into an economic basket case like present-day Greece." The power in speech is used specifically with judgement in this example with the statement "economic basket case like present-day Greece".
