What Skills Help You Decide If Persuasion Is Convincing?

“She’s only been here a week! How do you know?” you ask.
Before you’re persuaded to think or act a certain way, you evaluate the evidence by digging deeper and asking questions.
Evaluating Evidence
Cam has drawn a conclusion but gives no evidence.
“Hey, our new basketball coach is great!” exclaims Cam.
You want to know how Cam has reached his conclusion, so you ask a question.
Before you’re persuaded to think or act a certain way, you evaluate the evidence by digging deeper and asking questions.
Evaluating Evidence
Cam is asking you to trust his opinion, but he still hasn’t presented any evidence.
“I just know. Take my word for it,” says Cam.
“No way! Tell me what’s so great about her.”
You are still looking for a good reason to believe him.
Before you’re persuaded to think or act a certain way, you evaluate the evidence by digging deeper and asking questions.
Evaluating Evidence
“Well, she looks like this other really cool coach I used to know.”
This statement only makes you think, “What does that have to do with anything?”
You ask, “So what? What else do you know?”
You dig deeper. So far Cam isn’t making a lot of sense.
Before you’re persuaded to think or act a certain way, you evaluate the evidence by digging deeper and asking questions.
Evaluating Evidence
“Her teams have won almost all of their games for the last five years. And she showed me how to fix a problem I’ve been having with my jump shot.”
Cam has finally presented you with two good pieces of evidence that support his claim that the new coach is great.
With persuasive writing, you have to read carefully to decide if the evidence is strong enough to support the author’s claims.
Evaluating Evidence
Claim: The city’s anti-littering campaign has been a success.
Evidence: The increased fines are working.
Hmmm . . . Not very convincing.
With persuasive writing, you have to read carefully to decide if the evidence is strong enough to support the author’s claims.
Evaluating Evidence
Now, that’s more like it.
Claim: The city’s anti-littering campaign has been a success.
Evidence: The mayor’s office reports that workers have spent about 50 percent less time picking up trash than they did before the program was in place.
Adequate Evidence
Evaluating Evidence
Is there enough evidence to support the writer’s points?
Ms. Helen Silva, Director of Parks and Recreation, stated, “Since the anti-littering program went into effect, our parks are cleaner, and so are the city streets. The program is definitely working.”
• Sometimes one example or fact is adequate.
Quotes from respected experts, like this one, can go a long way toward supporting a claim.
Adequate Evidence
Evaluating Evidence
Is there enough evidence to support the writer’s points?
A survey of 500 city residents revealed that 80 percent of them have noticed an improvement in the cleanliness of the streets. Also, the city council has received fewer complaints about litter.
• Sometimes the writer will need to provide several facts and statistics to be convincing.
Appropriate Evidence
Evaluating Evidence
If you find yourself asking, “What does this have to do with anything?” you are probably looking at inappropriate evidence.
The city’s anti-littering campaign is working. My uncle is on the committee that developed the campaign.
Does the writer’s evidence relate directly to his or her ideas?
Huh?
Appropriate Evidence
Evaluating Evidence
The city’s anti-littering campaign is working. The Committee for a Cleaner City has reported that littering is down significantly.
Does the writer’s evidence relate directly to his or her ideas?
This statement relates directly to the idea that the campaign is working.
Accurate Evidence
Evaluating Evidence
Don’t assume everything in print is accurate. If something doesn’t sound right, check the source.
According to a June 15 article in the Daily Gazette, the City Council received official recognition from Governor Terrell, who commended them on the success of the anti-littering campaign.
Is the evidence correct? Does it come from a source you trust?

Warning! An argument may look nice and neat on the printed page, but that doesn’t mean it is well thought out.
Once you’ve evaluated the evidence, look closely at the writer’s conclusion.
