Langan John. Ten Steps to Advancing College Reading Skills

Fifth Edition. — Townsend Press, 2010. — 340 p.Critical reading includes the following three abilities:
Separating fact from opinion. A fact is information that can be proved true through objective evidence. An opinion is a belief, judgment, or conclusion that cannot be proved objectively true. Much of what we read is a mixture of fact and opinion, and our job as readers is to arrive at the best possible informed opinion. Textbooks and other effective writing provide informed opinion—opinion based upon factual information.
Detecting propaganda. Advertisers, salespeople, and politicians often try to promote their points by appealing to our emotions rather than our powers of reason. To do so, they practice six common propaganda techniques: bandwagon, testimonial, transfer, plain folks, name calling, and glittering generalities.
Recognizing errors in reasoning. Politicians and others are at times guilty of errors in reasoning—fallacies—that take the place of the real support needed in an argument. Such fallacies include circular reasoning, personal attack, straw man, false cause, false comparison, and either-or.
