Fallacies are encountered frequently in every day arguments. "An argument is fallacious when it contains one or more logical fallacies. A logical fallacy - or fallacy, for short - is an argument that contains a mistake in reasoning" (Critical Thinking, 2000).

"Recent studies suggest that emotions are essential to decision-making. Trust is a factor in buying decisions, especially when the...
