TV and Logic
Probably the single most important requirement for detecting fallacies in ordinary language is alertness. The reader or listener must pay close attention to what the arguer is saying. What is the conclusion? What are the reasons given in support of the conclusion? Are the reasons relevant to the conclusion? Do the reasons support the conclusion? If the reader or listener is half asleep, or lounging in that passive, drugged-out state that attends much television viewing, then none of these questions will receive answers. Under those circumstances the reader or listener will never be able to detect informal fallacies, and he or she will accept the worst reasoning without the slightest hesitation.
