Are we rational human beings? Do we follow all forms of logic? Do we only act if it feels right? Do we even want the facts all the time? Have you ever tried to persuade an emotional person with logic? We generally think we make decisions based on facts, but truly this is not the case. It has been found that when people agree with a particular message, they tend to perceive it as being more logical or rational. On the other hand, when people disagree with the message, they perceive it as an emotional plea.1 The truth is that that our decision-making process relies on a mixture between emotion and its partner, logic. However, we cannot rely entirely on emotion until our logical side has been engaged.

In one study, twenty-one students prepared speeches that were written from either a logical or an emotional standpoint. The speeches were presented, filmed, and then evaluated by other college students. Interestingly, there was no real consistency in the findings except that speeches bearing a message that the evaluator agreed with were rated as more rational (even if they were intended to be emotional), while those the evaluator did not agree with were considered to be more emotional (even though some of those were intended to be logical). It seemed that whether a speech was considered logical or emotional depended on the listener.

The logical side of an argument appeals to our reason. Reasoning is the process of drawing a conclusion based on evidence. For an argument to be legitimate, it has to be true and valid, and logical reasoning must be used to back it up. Many persuaders and marketers use faulty forms of logic, leaving gaping holes that require the audience to make assumptions and fill in the blanks. These are called logical fallacies. A fallacy is, very generally, an error in reasoning. It differs from a factual error, which is simply being wrong about the facts. In other words, a fallacy is an "argument" in which the premises don't completely support the conclusion. In the next section, some of the most common logical fallacies are outlined.
