How can cognitive dissonance help you as a communicator?

A communicator that has cognitive dissonance would benefit because they would be able to examine both sides of an argument very closely. The communicator can then make informed decisions as to what information is delivered and in what way. 

If a communicator is passionate about one side of the argument and does not research the other side, then they are not informed and the message will be weak. Any opportunity for another communicator to tear away at the facts may cause the original message to be lost. It also raises some ethical flags, because the information needs to be researched and the other side needs to be understood. This could cause serious trouble for a communicator with libel and slander laws. 

A communicator with a little cognitive dissonance benefits as they would not likely make this mistake.

Cognitive dissonance found in an audience would also help a communicator, as it gives an audience that can be impacted. As individuals hold two different beliefs, it gives the communicator an opportunity to sway them in one direction. This type of communication would benefit from having strong information that has been validated.  The presentation of week information may cause the audience to lose interest or sway in the opposite direction.
