Propaganda Techniques:

Bandwagon-suggests that you need something or you should believe something because everyone else is already has it or believes it. "Joining the crowd, climbing on the bandwagon and joining the parade" are examples of 'bandwagon' lingo.
Testimonial-uses a famous person, such as an actor or an athlete, to promote an idea or a product. People who use snob appeal associate the product or idea they're promoting with power, wealth, or membership in a special group.
Stereotypes-refer to members of a group as they were all the same. For instance, an article stating that all professional wrestlers have limited intelligence is unfair.
Stereotypes often lead to prejudice or forming unfavorable opinions with complete disregard for the facts.
Name-calling-offers no reasons or evidence to support their position. Instead, they attack opponents by calling them names, such as "busybodies," "nitpickers," or "rumormongers."
Emotional appeals-get the reader's feelings involved in the argument. Some writers use vivid language and give reasons, examples and anecdotes.
Logical appeals-makes sense because they're based on correct reasoning. They appeal to your brain with reasons and evidence. Make sure the writer has good reasons to support each opinion or conclusion. (Facts, personal experiences, examples, statistics and statements by experts on the issue should back up each reason.)
Hasty generalization-valid generalizations are based on solid evidence. Not all generalizations are valid.
