Vocabulary
When you encounter two opposing views on an issue, you have to
• evaluate the credibility of each point of view
Evaluating Pro and Con Arguments
• evaluate the arguments and decide which is stronger
• decide which side you believe
Understand the Arguments
Make sure you understand the issue and the opinion, or claim, presented in each argument.
Evaluating Pro and Con Arguments
• Check your understanding by paraphrasing the arguments in your own words.
Identify the Support
Look for logical appeals and evidence. Types of evidence can include
• facts (statements that can be verified objectively)
Evaluating Pro and Con Arguments
• statistics (numerical facts)
• examples
• comments from experts
Identify the Support
Also, take into account any emotional appeals the writer uses. Emotional appeals can include
Evaluating Pro and Con Arguments
• loaded words
• anecdotes (colorful or emotional stories)
What is the author’s claim?
What evidence is provided to support the claim?
Quick CheckThe reason it’s so hard to find answers is, in part, a matter of ignorance. Only in the past half-century have instruments begun to be set out at sea and on land to monitor what’s actually happening. And only since about 1972 have orbiting satellites been able to even roughly track what’s happening to ice at the poles. Because there is no long-term history of climate variability, we can’t know whether what seems unusual now is actually unusual in global climate.

To decided which argument is stronger and why, consider these questions:
Is the argument logical?
• Watch out for common fallacies, or errors in logical thinking.
Evaluating the Credibility
• Do the reasons the author presents make sense? Are they relevant to the issue?
Fallacies
Circular Reasoning—presenting restatements of the author’s opinion as reasons or conclusions
All students in the ninth grade need to get a laptop computer because it’s essential for all ninth-grade students to have one.
False Cause and Effect—suggesting that one event caused another just because the two events happened in sequence
Spelling scores for ninth-grade students went up after all students got laptop computers.
Evaluating the Credibility
Fallacies
Hasty Generalizations— making a broad, general statement or conclusion without sufficient evidence. Hasty generalizations are usually based on only one or two cases
I should get a laptop computer because two of my friends have them, and their grades went up.
Attacking the person—making a personal attack against someone with an opposing viewpoint rather than focusing on the issue
Principal Smith says ninth graders don’t need computers because he is anti-computer and doesn’t like students.
Evaluating the Credibility
How comprehensive is the support?
Evaluating the Credibility
• Is there evidence to support every generalization or argument the author makes?
• Unsupported generalizations weaken an argument.
Evaluating the Credibility
Does the author deal with opposing evidence?
• Does the writer discuss opposing evidence to anticipate objections?
• Addressing an opponent’s viewpoint is important when an issue is controversial and many people have clear pro (for) and con (against) views.
What might an opposing argument be?

Because there is no long-term history of climate variability, we can’t know whether what seems unusual now is actually unusual in global climate.
• Does the structure help the writer’s strongest reasons stand out? (Readers generally remember the beginning or ending of a piece most clearly.)
• Writers commonly use cause and effect and compare and contrast writing structures to make their arguments.
What is the author’s intent?
Evaluating the Credibility
• Is the author trying to persuade you or to issue a call to action?
• Do there seem to be hidden agendas in the writer’s arguments?
What is the author’s intent?

• The tone of a persuasive argument should be serious, calm, and reasonable.
• You should question the credibility of the argument if the tone is humorous, angry, or highly emotional.
• Also, be wary of authors who exaggerate unimportant issues or make light of serious issues.
What is the author’s tone?
Quick Check
How does the tone affect the author’s argument?
