asking the right questions是我在准备gmat考试的时候,详细阅读过好多次的一本书,这本书奠定了我去分析问题的逻辑基础。现在,博士申请结束,在开始新的学术生涯的时候,我再一次发现这本书非常好,所以分享给大家~
下面是我的笔记哒~~~
Asking the right questions
Critical thinking, (1) awareness of a set of interrelated critical questions; (2) ability to ask and answer critical questions at appropriate times; and the (3) desire to actively use the critical questions.
Chapter 1
The sponge and panning for gold, the sponge approach emphasizes knowledge acquisition; the panning-for-gold approach stresses active interaction with knowledge as it is being acquired.
Mental check: am I panning for gold?
(1) Did I ask “why” someone wants me to believe something? (2) Did I take notes as I thought about potential problems with what was being said? (3) Did I evaluate what was being said? (4) Did I form my own conclusion about the topic?
e.g. (1) what does the author mean by “overwhelming majority” or by “typical murderer”? is the minority still a substantial number of murderers who kill relatives in a moment of anger? (2) what does “gun owners” mean? Are they the ones who buy the kind of guns that gun control advocates are trying to ban? (3) how adequate were the cited research studies? Were the samples sufficiently large, random, and diverse? (4) has the author lied with statistics by impressing us with large, rather precise numbers, like 581,000, and 645,000? What is the basis for these numbers? Can we rely on them? (5) what possible benefits of gun control are not mentioned? Have important studies that disagree with the author’s position been omitted? (6) is it legitimate to assume that because some famous people own guns then owning guns is desirable? Do these people have special expertise concerning the pros and cons of gun ownership? (7) how many people are killed each year by handguns who would not have been killed were such guns not available? (8) why did the person writing the essay fail to explain how we could encourage better enforcement of existing gun control laws to demonstrate his sensitivity to the harm that guns sometimes facilitate?
Emotional involvement should not be the primary basis for accepting or rejecting a position. Ideally, emotional involvement should be most intense after reasoning has occurred. Thus, when you read, try to avoid letting emotional involvement cut you off from the reasoning of those with who you initially disagree.
Weak-sense critical thinking V.S. Strong-sense critical thinking
Weak-sense critical thinking is the use of critical thinking to defend your current beliefs. Strong-sense critical thinking is the use of the same skills to evaluate all claims an beliefs, especially your own. “He who knows only his side of the case knows little of that. His reasons may have been good, and no one may have been able to refute them. But if he is equally unable to refute the reasons on the opposite side he has no ground for preferring either opinion.”
The right questions:
(1) what are the issues and the conclusions?
(2) what are the reasons?
(3) which words or phrases are ambiguous?
(4) what are the value conflicts and assumptions?
(5) what are the descriptive assumptions?
(6) are there any fallacies in the reasoning?
(7) how good is the evidence?
(8) are there rival causes?
(9) are the statistics deceptive?
(10) what significant information is omitted?
(11) what reasonable conclusions are possible?
Chapter 2
Issue & conclusion
An issue is a question or controversy responsible for the conversation or discussion. It is the stimulus for what is being said.
Descriptive issues are those that raise questions about the accuracy of descriptions of the past, present, or future. E.g. do families who own pets have fewer arguments with one another? What causes high blood pressure? Who made the decision to increase our sales taxes? How much will college cost in the year 2010?
Prescriptive issues are those that raise questions about what we should do or what is right or wrong, good or bad. E.g. should capital punishment be abolished? What ought to be done about social security? Must we outlaw SUVs or face increasing rates of asthma?
A conclusion is the message that the speaker or writer wished you to accept.
Issues and conclusion, examples:
will owning a pet increase how long we live?
yes, it sill increase our life span by an average of 15 years.
do pets bring joy to our lives?
pets bring joy to the lives of everyone who owns them.
Searching for the conclusion
Conclusions are inferred; they are derived from reasoning. Conclusions are ideas that require other ideas to support them. In contrast, unsupported claims are what we refer to as mere opinions.
To believe one statement (the conclusion) because you think it is well supported by other beliefs is to make an inference.
Sometimes, communicators will not make their conclusions explicit; in such cases you will have to infer the conclusion from what you believe the author is trying to prove by the set of ideas she has presented.
Clues to discovery: how to find the conclusion
Clue 1: ask what the issue is.
(1) look at the title; (2) look at the opening paragraph; (3) skim several pages;
Clue 2: look for indicator words.
Consequently, hence, points, thus, it follows that, shows that, indicates that, suggests that, therefore, to the conclusion that, the point I’m trying to make is, it is highly probable that, proves that, the truth of the matter is;
Clue 3: look in likely locations
At the beginning; at the end
Clue 4: remember what a conclusion is not
Examples; statistics; definitions; background information; evidence
Clues 5: check the context of the communication and the author’s background
Clues 6: ask the question, “and therefore?”
Chapter 3 what are the reasons?
Reasons and argument
Reasons are beliefs, evidence, metaphors, analogies, and other statements offered to support or justify conclusions. They are the statements that together form the basis for creating the credibility of a conclusion. Reasons are explanations or rationales for why we should believe a particular conclusion.
You cannot determine the worth of a conclusion until you identify the reasons.
Reasons + conclusions = argument
Several characteristics of arguments grab our attention: (1) they have intent. Those who provide them hope to convince us to believe certain things or act in certain ways. Consequently, they call for a reaction. We can imitate the sponge or the gold prospector, but we ordinarily must respond somehow. (2) Their quality varies. Critical thinking is required to determine the extent of quality in an argument. (3) They have two essential visible components – a conclusion and reasons. Failure to identify either component destroys the opportunity to evaluate the argument. We cannot evaluate what we cannot identify.
Initiating the questioning process
As you determine a communicator’s reasoning structure, you should treat any idea that seems to be used to support her conclusion as a reason, even if you do not believe it provides support for the conclusion. At this stage of critical thinking, you are trying to identify the argument.
Words that identify reasons
(1) As a result of; (2) for the reason that; (3) because of the fact that; (4) in view of; (5) is supported by; (6) because the evidence is;
