Chapter Quiz

Identify the following arguments either as NF for not fallacious or by the types of fallacious arguments indicated for each section. In some cases, you may find that more than one fallacy applies; choose the one you feel to be the most appropriate. Be prepared to defend your answers.

Inductive Reasoning and Inductive Fallacies

Chapter Quiz

  7. “Bloodletting reduces fever. This patient has fever. This patient needs bloodletting.” This syllogism shows valid reasoning although both premises may not be true. T
  8. “White-skinned people are superior to dark-skinned people. Therefore, it is the manifest destiny of white-skinned people to rule dark-skinned people.” No country would ever accept such fallacious reasoning as this. F

5. If information is relevant, it is
b. Related to the topic you are researching.


SUMMARY CHAPTER 14 CRCB

One must be an "open-minded skeptic" when considering internet sources. The seven-step internet source evaluation system is best remembered by using the mnemonic 2RCA, Relevancy, Reliability, Credibility and Accuracy. The seven steps are (1) know your purpose, (2) double-check facts and sources, (3) Consider the source, (4) Evaluate content, (5) determine intended audience, (6) evaluate the writing and lastly, (7) Use what you already know.

Chapter 13 CRCB Summary

Benjamin Bloom was well known for "Bloom's Taxonomy". It lists the six levels of thinking teachers use in testing their students. Critical reading involves asking and answering questions at these six levels. The levels are knowledge, comprehension, application, analysis, synthesis, and evaluation.

Chapter 13 CRCB Exercise 13a

Knowledge Level Questions

Read each question and choose the best answer from the choices given.

1. What example is used to illustrate an inappropriate way of disagreeing with another group member?
b. Your proposal is the work of a fool with one eye and half a brain.

2. Which of the following is not a rule of proactive conflict management?
c. Employees with the most seniority are best at making a decision that affects us all.

3. According to the excerpt, why is conflict constructive?
a. Because every person has the right to disagree, if necessary.

Chapter 12 CRCB Summary

Arguments have at least one conclusion and one reason. A way to look for the argument is through word clues. The two types of arguments are deductive and inductive. Arguments can be evaluated by determining dependability and distinguishing fact from opinion. Another way of evaluating them is by detecting fallacies. Some examples of fallacies are Hasty Generalization, Red Herring, False Cause, Slippery Slope, Ad Hominem and Circular Reasoning.

Detecting Fallacies

Read the following arguments and determine if they contain a fallacy or error in reasoning; if so, identify what kind it is. The first one is modeled for you.

1. If you don’t get good grades, you’ll never get to college.
If you don’t get into college, you’ll never get a job.
Therefore, you’ll end up a homeless person in some major city.
Error in reasoning? Yes
If so, which fallacy was commited?
Slippery slope (an event will precipitously lead to another event, which will lead to another event, and so on.)

2. Flowers are so beautiful in the springtime.
The air seems cleaner and the grass seems greener.
In my opinion, there is something so rejuvenating about the onset of spring.
Error in reasoning? None
If so, which fallacy was commited?

3. The doctor said that I could either stick to his diet plan, or accept being overweight.
Error in reasoning? Yes
If so, which fallacy was commited? Either/Or (allows for only two answers to a problem when in fact there may be more)

4. Ima Geeke, mayoral candidate, suggest changing several local laws. She believes that the laws need to be more reflective of the times. She’s just a generation X’er; what does she know?
Error in reasoning? Yes
If so, which fallacy was commited? Ad Hominem (they avoid the true issue by attacking the person they disagree with)

5. Every student who earns a 3.0 grad point average or higher is eligible for the Lah D. Dah scholarship. I have a 3.2 GPA. If I apply, I could get the scholarship.
Error in reasoning? Yes
If so, which fallacy was commited? Circular Reasoning (make two statements that essentially say the same thing)

6. If I go to the casino with Andy, I know that I’ll win money.
The first time I went to the casino with Andy, I won $10.
The second time, I won $50.
Error in reasoning? Yes
If so, which fallacy was commited? False Claim (fails to explain how the conclusion and reasons are connected to each other, or provides unclear or faulty connections)

7. Judy gave an outstanding presentation in class today, and I admit that she seems like a good candidate for student council. But I am leery of someone whose parents support euthanasia.
Error in reasoning? Yes
If so, which fallacy was commited? Red Herring (introduce irrelevant material to distract readers) or Ad Hominem ( avoid the true issue of an argument by attacking)

8. It’s easy to prove that Santa Claus exists. Most people do believe in Santa, even if they are not able to define exactly what they mean in the same way. To some it means a real person living in the North Pole. To some it’s a spirit of giving, a supernatural force. And to others, he’s a saint. But setting aside the differences in these interpretations, we can be confident that there is a Santa because Santa would not cause so many people to believe in him if he did not exist.
Error in reasoning? No
If so, which fallacy was commited?

9. I’m not bringing my brother to the Rangers’ football games anmore. Every time I bring him, the team loses.
Error in reasoning? Yes
If so, which fallacy was commited? False Cause

10. May Aspirin will help relieve headaches because May Aspirin contains a secret new ingredient, which serves to increase the strength of relief it provides. What is the secret ingredient?

If so, which fallacy was commited? Circular
