Communicative messages surround us. Most try to teach us something and/or influence our thoughts or behaviors. As with any type of communication, some messages are more engaging and effective than others. I’m sure you have experienced the displeasure of sitting through a boring class lecture that didn’t seem to relate to your interests or a lecture so packed with information that your brain felt overloaded. Likewise, you have probably been persuaded by a message only to find out later that the argument that persuaded you was faulty or the speaker misleading. As senders and receivers of messages, it’s important that we be able to distinguish between informative and persuasive messages and know how to create and deliver them.
