Title: Thinking Skills
1Thinking Skills
- Chapter 2
- Critical Thinking
2Critical Thinking
- Critical thinking is reasonable, reflective
thinking focused on deciding what to believe or
do. - It involves using basic thinking skills and
processes to analyze arguments and generate
insight into particular meanings and
interpretations to develop cohesive, logical
reasoning patterns and understand assumptions and
biases underlying particular positions and to
attain a credible, concise, and convincing style
of presentation.
3Concept of Critical Thinking
- Critical thinking has been described in different
ways - the evaluation of reasoning and arguments
(Ruggiero) - reasonable, reflective thinking directed at
deciding what to believe or do (Ennis) - the application of standards to our judgments
(Paul Elder) - What these conceptions of critical thinking have
in common is that before we accept a judgment, we
should be sure that it is supported by good
reasons. If it is not, we should not accept it.
4- The critical thinking skills that are the most
frequently needed in our personal and
professional lives, fall into two categories - skills related to basic information that we get
from a variety of sources, including media,
textbooks, other people, and even our own
observations (determining the accuracy of
observation, determining the reliability of
sources). - skills related to inferences in which we draw
conclusions that we do not verify directly from
information offered as evidence to support them
(causal explanation, prediction, generalization,
and reasoning by analogy), or inferences in which
we deduce conclusions (conditional reasoning).
5Goals of Critical Thinking
- Critical thinking is considered essential for
democratic citizenship the goal of teaching
critical thinking is to develop people who are
fair-minded, objective, and committed to clarity
and accuracy. - Every idea (or project) has its positive points
and negative ones. Critical thinking does not
mean to discover the negative points only in your
opponents idea or point of view. The goal of
critical thinking is to bring out the truth even
if it meant your loss.
6Traits of Critical Thinker
- 1. Intellectual Humility (rational modesty)
Awareness of the limits of ones knowledge,
including sensitivity to circumstances in which
ones native egocentrism is likely to function
self-deceptively sensitivity to bias and
prejudice in, and limitations of ones view
point. - 2. Intellectual Courage The willingness to
face and assess fairly ideas, beliefs, or
viewpoints to which we have not given a serious
hearing, regardless of our strong negative
reactions to them. - 3. Intellectual Empathy(understanding)
(Justice) recognizing the need by imaginatively
putting oneself in the place of others to
genuinely understand them, this will lead to an
intellectual justice.
7- 4. Intellectual good Faith (Integrity or
reliability ) Recognition of the need to be
true to ones own thinking, to be consistent
(steady) in the intellectual standards one
applies, to hold ones self to the same thorough
standards of evidence and proof to which one
holds ones opponents. - 5. Faith in Reason Confidence that in the
long run ones own thinking and higher interests
and those of humankind at large will be served
best by giving the freest play to reason, by
encouraging people to come to their own
conclusions by developing their own rational
abilities.
8- 6. Intellectual Independence Critical thinking
is autonomous (self-directed) thinking, it is the
willingness to tackle all viewpoints
sympathetically (kindly) and to assess them with
the same intellectual standards without being
affected by ones own feelings or interests, or
the feelings or interests of ones friends,
community, or nation. - 7. Intellectual Perseverance (persistence)
Willingness to pursue (follow) intellectual
insights (visions) and truths despite
difficulties, obstacles, and frustrations. - Â
9Skills Used in Critical Thinking
- A wide range of skills in critical thinking have
been identified through the literature, e.g. - Focusing on a question
- Analyzing arguments
- Judging the credibility of a source
- Deducing and judging deductions
- Observing and judging observation
- Comparing, Classifying
- Ordering, Representing
- Summarizing, Restructuring, Predicting
- Elaborating (explaining), Identifying
attributes, relationships.
10Barriers of Critical Thinking
- 1. Lack of Information or Ignorance
- Critical thinking involves the evaluation of
information and its conceptualization (forming
ideas), application, analysis and synthesis.
Therefore, a critical thinker should have enough
liable (right) information to be able to achieve
his/her goal. - 2. Self Deception (tricking)
- It is not easy to face our failure, many times
we blame it on others. By deceiving ourselves we
wont be able to analyze our mistakes and treat
them. Â - 3. Reliance on Expert Opinion
- Experts have their mistakes, and we can be
intimidated and influenced by their opinion.
Being a critical thinker means having a cautious
skepticism and gullibility (innocence), having an
open mind while not allowing him/herself to be
conned (cheated). The critical thinker is able to
recognize as well as evaluate the adequacy and
applicability of evidence.
11- 4. Bias and Prejudice and Desire
- Human action is grounded (stuck) in human
motives and motives are typically grounded in
human desire and perceived interest. We routinely
categorize, make assumptions, interpret, and
infer from within a viewpoint we use to advance
our personal ends and desires. We are, in a
word, naturally prejudiced in our own favor. It
is not enough to be taught to be ethical, and
respectful of human rights. The mere conscious
will to do good does not remove prejudices which
shape our perceptions or eliminate the on-going
drive to form them. To minimize our egocentric
(selfish) drives, we must develop critical
thinking in character as well. Indeed we must
develop and refine our intellectual skills as we
develop and refine our intellectual character, to
embed (insert) the skills in our character and
shape our character through the skills.
12Evaluating Evidence
- 1. Accuracy of Observation
- Eyewitness accounts (explanations) are a special
case of primary source information based on
direct observation. In this instance, the
conditions of observation, the use of
observation-enhancing instruments, the persons
expectations of what he or she is seeing, and
when the report was recorded are all important. - Â
- 2. The Persons Expertise
- The main source of information must be well
informed and expert on the subject in question.
If we need a medical information we should get it
from a specialized doctor or specialized
journal.. and so on. - Â
13- 3. Disagreement or agreement among experts
- It is a mistake to think that because someone is
an expert in a field, his or her judgment must be
accurate. Experts often disagree and may have
vested interests (private) or biases. Because
the general public lacks technical expertise, it
has no way to determine who to believe. As a
result, people tend to reject expert analysis and
believe what they want to believe. A good
critical thinker must weigh all factors and
establish a pattern of support for or against a
sources reliability (trustworthiness) - 4. Conflicts of Interest
- The believability of fact-finding efforts is
sharply reduced when the experts doing the
fact-finding work are likely to benefit
personally by providing misleading information.
In this case, opponents and the general public
are likely to doubt the truthfulness or accuracy
of the expert's conclusions--even if the expert
is acting reasonably. - Â
14- 5. Reputation / Lack of credibility
(trustworthiness) - Sometimes, we get information about one of the
factors that influence credibility. We may find
out, for example, that an individual who provides
some important information on a current matter
may not have given accurate information in the
past. His past record casts some doubt on
whether he is a reliable source for the
information he is providing now. However, an
error in the past is not a sufficient support for
unreliability in the present. Also, the source
of professional and personal reputation is
important according to the type of information we
are gathering.
15Finding resources is about finding the
information you need to make decisions and create
solutions.
- Knowing how to find information is important
because it arms you with accurate information. - Our study focus here will be on three types of
resources - 1- The internet.
- 2- The library.
- 3- Human resources.
161- Internet resources
- Searching the internet for resources should not
be confusing you just need to know what you are
looking for, and determine the best way to find
it. - First of all, you can start with
- A. search engines
17 Examples of search engines
- http//www.google.com
- www.alltheweb.com
- www.yahoo.com
- www.bing.com
- You can also go through many sites at one time.
This type of search engines called meta-search
engines. - Example of such sites
- www.surfwax.com
- Neither search engine can distinguish between
good and bad sites. They simply list everything
they can find which meets your search criteria.
18B. Subject directories
- This method of information searching is often
useful and genuine, because the sites the
directories list, have been chosen by qualified
people. Thus, what believed to be poor content,
not listed. - Some directories hire experts in various fields
to write guides to their chosen subjects, and
also to provide links to related sites.
19 Example of such subject directories
- About.com (www.about.com) over 50,00 subjects
with links to a million websites. - Academic Info (www.academicinfo.net)
consistently maintained to add free educational
resources (for late high school level and above)
while weeding out outdated ones. - Librarians Index (www.lii.org) over 11,000
Internet resources selected as the best by
librarians. - Infomine (www.infomine.ucr.edu) aimed at
university-level instructors and students,
contains 115,000 Internet resources selected by
university librarians.
20C. Encyclopedias
- The third way to find what are you looking for is
searching directly the internet on a site at
which you believe the information may be found. - Examples of Encyclopedias sites
Wikipedia.org a free access encyclopedia has its
information from the contribution of public
users. Xrefer.com London-based reference book
search engine searches over 50 encyclopedias,
dictionaries (in many categories), and
thesauri Encyclopedia.com Columbia Encyclopedia,
6th edition Britannica.com the first few
paragraphs of each article are free, so if you
need very basic facts, chances are you will get
them for 50 per year you can have total access
to the site Encarta.com some entire entries are
free, others are blocked to those who have not
paid 69 per year for the CD-ROM or DVD
21D. Dictionaries
- Dictionary.com searches a dozen dictionaries at
one time, including American Heritage (fourth
edition),Websters Revised Unabridged (1998),
Princeton Universitys WordNet, and the CIA World
Factbook. - M-W.com Merriam Websters older dictionaries
searched free for access to the new eleventh
edition, the annual fee is 14.95
(merriam-webstercollegiate.com).
22Practice
- Answer (T) true or (F) false for the statements
below. - ___ 1. Search engines direct you to the best
sites about the subject you are researching. - ___ 2. Doing research on the Internet sometimes
costs money. - ___ 3. Subject directories are created by
computers. - ___ 4. Some search engines search many other
search engines at the same time. - ___ 5. You can only find statistics at a library.
23 Roadblock to Good Resources
- The main roadblock, or obstacle of conducting a
good research is that sites with poor contents
reside side by side with accurate and legitimate
websites. Such sites (illegitimate, poor content)
may make fiction posing as facts, or simply
slipshod work, can look like real work. - The best way to avoid reliance on poor
information is to be suspicious. Do not take any
information you find on the Internet as truth
until you can substantiate it with duplicate
information on at least three other sites.
24Practice
- You are building a house and need to decide how
to heat it. The contractor can put in a natural
gas, or electric furnace. You want to choose the
option that is the least expensive to operate. A
search on the Internet yields five results. Which
website(s) will most likely have the information
you need to make a decision? - 1. www.epa.org the Environmental Protection
Agency - 2. www.ashrae.org/ the Society of Heating,
Refrigerating, and Air-Conditioning Engineers - 3. www.forestry.ext.edu educational site about
the use of wood in home heating units - 4. www.electricfurnaceswebe.com retailer of
electric powered home heating units - 5. www.energycodes.gov Kansas State Universitys
Engineering Extension website
252- The library (print resources)
- We need library in our searching for resources
because internet doesnt always have everything. - There are three important reasons to do research
at the library - A. librarians. They are trained professionals who
know how to find what you are looking for,
whether in the stacks or online.
26- B. Reliability of information. Not all of the
information you find on the Internet is accurate.
Anyone can publish online, and it is not always
easy to distinguish between reliable and
unreliable websites. Many sites containing bogus
information appear professional and well-written. - On the other hand, published books (printed
ones) that we find in the library have been
through many layers of safety nets before they
reach the shelves of a library. They are
typically written, edited, proofread,
fact-checked, published, and then selected by a
librarian for purchase.
27- C. Price. The use of a library, including all of
its electronic services, is free. Some of the
research resources on the Internet are not. There
are sites that give away some information, but
charge for full access to their site. Others will
not let you in at all unless you are a
subscriber. Some Internet resources charge
prohibitively high subscription prices, such as
the Oxford English Dictionary (currently 550 per
year). Libraries often pay these prices and
provide full access.
283. Going to the experts
- Sometimes, you cant find out what you need to
know from a website or the library, such as
interest rates on mortgages that change daily, in
such cases, you need to find a person or people
who have the information you are looking for. - Who are experts Experts are simply those who
know their subjects and can be relied upon to
supply correct information. - They might know about it because they have
studied it or worked with it long enough to be
considered highly informed.
29 Checking credentials
- before relying on an expert, determine that the
person has the proper credentials. - Ask questions about where they are getting their
information from. - On what sources do they rely?
- How are they qualified to provide you with the
information you are looking for?
30Practice
- The college you will attend in the fall has a
rule that all incoming freshman must take at
least two courses outside their major during
their first year at the school. After looking at
the course catalog, you determine that you only
have room for one such course. You need to know
how steadfastly the college maintains this rule.
Must you drop a course in your major, or can you
take a required course outside your major as a
sophomore? How will you get the information you
need? - a. Write a letter to the President of the college
- b. Check the schools website
- c. Look it up in the brochure
- d. Call the registrar
31Argument and Reasoning
- Statement and Claims
- For the purposes of critical thinking, all
sentences can be divided into those that can be
true or false, and those that cannot. Only a few
sentences cannot be true or false commands
(Just do it!), exclamations (How beautiful!), and
questions (Why not?). - The vast majority of all sentences in critical
thinking are called statements or claims. Note
that you dont need to know whether a statement
is true or false, just that it has the form of
sentences as Before he died, Elvis was thinking
of becoming a vegetarian.
32- Arguments
- An argument is a series of statements used to
persuade someone of something. That something
is called the conclusion or a claim. The first
job in analyzing any argument is to identify its
conclusion. One way to identify conclusions, or
other parts of an argument, is to look for their
indicators. - Â
33- Propositions (offers)
- A proposition is a statement which is either true
or false. The proposition is the meaning of the
statement, not the precise arrangement of words
used to convey that meaning. - Premises
- Premises (evidences) are statements that directly
support the conclusion or to look at it another
way, the reasons for accepting the argument.
Premises are only premises in the context of a
particular argument they might be conclusions in
other arguments. Â
34I like Ahmad. Ahmad is a nice boy. So he will
receive a reward from his school, because Ahmad
is really smart boy.
35- You should always state the premises of the
argument explicitly. Failing to state your
assumptions is often viewed as suspicious, and
will likely reduce the acceptance of your
argument. - The premises of an argument are often introduced
with words such as "Assume...", "Since...",
"Obviously..." and "Because...." It's a good idea
to get your opponent to agree with the premises
of your argument before proceeding any further. - The word "obviously" is also often viewed with
suspicion. It occasionally gets used to persuade
people to accept false statements, rather than
admit that they don't understand why something is
'obvious'. So don't be afraid to question
statements which people tell you are 'obvious' --
when you've heard the explanation you can always
say something like "You're right, now that I
think about it that way, it is obvious."
36- Inference
- Once the premises have been agreed, the argument
proceeds via a step-by-step process called
inference. - In inference, you start with one or more
propositions which have been accepted you then
use those propositions to arrive at a new
proposition. If the inference is valid, that
proposition should also be accepted. You can use
the new proposition for inference later on.
37- Conclusion
- Hopefully you will arrive at a proposition which
is the conclusion of the argument - the result
you are trying to prove. The conclusion is the
result of the final step of inference. It's only
a conclusion in the context of a particular
argument it could be a premise or assumption in
another argument. - The conclusion is said to be affirmed(stated) on
the basis of the premises, and the inference from
them. Conclusions are often identified by phrases
like "therefore..." or "...implies that.
38I like Ahmad. Ahmad is a nice boy. So he will
receive a reward from his school, because Ahmad
is really smart boy.
39Types of Arguments
- 1. Deductive (logical) Argument
- Is generally viewed as the most precise and the
most persuasive. It is an argument in which the
premises provide (or appear to provide) complete
support for the conclusion. - A good deductive argument is known as a valid
argument and is such that if all its premises are
true, then its conclusion must be true. If all
the argument is valid and actually has all true
premises, then it is known as a sound (thorough)
argument. If it is invalid or has one or more
false premises, it will be unsound. -
40Example
- 1. If you place wood in the fire, it will burn
(i.e., if P then Q) - 2. This is a piece of wood (i.e., P)
- 3. Therefore, it will burn (i.e., Q)
-
- If the premises are all true, then so is the
conclusion. In deductive terms, as an argument,
this is both valid and sound. Yet how do we know
that the premises are in fact true? This is
where inductive reasoning proves useful.
41- 2. Inductive Argument
- Is an argument such that the premises provide
(or appear to provide) some degree of support
(but less than complete support) for the
conclusion. Induction is usually described as
moving from the specific to the general.
Arguments based on experience or observation is
best expressed inductively. -
- The reasoning might go something like thisÂ
- Most of French class students are English.
- John is a student in the French class.
- 3. Therefore, John is English.
42- inductive generalization when we generalize form
a number (n) of cases that we know to be true,
and infer that the same thing will remain true in
all future cases involving what we believe to be
wood and fire. - argue causation Inductive arguments are
evaluated according to the degree to which the
conclusion is probably true, as distinct from
conclusively true in deductive arguments. In
terms of validity, an inductive argument is
neither valid nor invalid.
43- Inductive arguments are evaluated according to
the degree to which the conclusion is probably
true, as distinct from conclusively true in
deductive arguments. In terms of validity, an
inductive argument is neither valid nor invalid. - A good inductive argument is known as a strong
(or "cogent clear) inductive argument. It is
such that if the premises are true, the
conclusion is likely to be true. - Example
- All of French class students are English.
- John is a student in the French class.
- 3. Therefore, John is English.
44Spotting arguments
- Spotting an argument is harder than spotting
premises or a conclusion. Lots of people shower
their writing with assertions, without even
producing anything you might reasonably call an
argument. - Sometimes people may state their conclusions
first, and then justify them afterwards. This is
valid, but it can be a little confusing. - A statement of the form "X because Y" can be
re-phrased as an equivalent statement, of the
form "Y therefore X."
45Evaluating Arguments
- 1. Comprehending and using language with
accuracy, clarity and discrimination - The critical thinker should notice the language
used in the argument, it should be clear and
comprehensive. The words should be precise and
do not imply other meanings. The critical
thinker should also distinguish the emotional
words used which may affect his/ her judgment. - 2. Distinguishing between facts and opinions
- It is very important to be able to distinguish
between facts and opinions, we may argue to
reject or accept opinions, but we cant argue
with facts.
46Practice
- Label each statement as either (F) fact or (O)
opinion. - ___ 1. The USA is bigger in size than the UAE.
- ___ 2. Ice cream is the most delicious dessert.
- ___ 3. I went to London for a vacation last year.
- ___ 4. Putting money in the stock market is a bad
idea.
47- 3. Applying integrated (unified) information
- The critical thinker should be able to
distinguish if his opponents arguments have
contradictory information. At the same time he
should check his argument and use only integrated
information. - 4. The sufficiency of premises
- Depending on the argument in question, we should
have enough premises to reach to a certain
conclusion. Take the following example - Premises 1 Fatima is a student in UAEU
- Premises 2 Fatima is taking a thinking skills
course - Conclusion Therefore, Fatima is majoring in
Education - As we notice in the previous example, the
sentences are clear, facts, integrated, yet they
are not enough to reach to that conclusion.
48Logical Fallacies
- Logical fallacies are errors that occur in
arguments. - Every argument makes some assumptions. A
convincing argument makes only warranted
assumptions, i.e., its assumptions are not
questionable or false. So, fallacies of
assumption make up one type of logical fallacy.
49- 1. The Bandwagon Fallacy (Peer Pressure)
- The Bandwagon is a fallacy in which a threat of
rejection by one's peers (or peer pressure) is
substituted for evidence in an "argument.
"Example - Joe "Bill, I know you think that 112. But we
don't accept that sort of thing in our group. " - Bill "I was just joking. Of course I don't
believe that." - Salem I like tennis, I think tennis is a good
sport. - Khalid What! Tennis is for girls, only weak boys
like tennis. - Ahmad I dont like anyone likes tennis. Soccer
is for champs. - Salem Oh! Youre right, soccer is better. I hate
tennis.
50- It should be noted that loyalty to a group and
the need to belong can give people very strong
reasons to conform to the views and positions of
those groups. Further, from a practical
standpoint we must often compromise our beliefs
in order to belong to groups. However, this
feeling of loyalty or the need to belong simply
does not constitute evidence for a claim. - 2. Straw Man Fallacy
- One of the characteristics of a cogent
refutation (rejection) of an argument is that the
argument one is refuting is not represented
fairly and accurately. To distort or misrepresent
an argument one is trying to refute is called the
straw man fallacy. It doesn't matter whether the
misrepresentation or distortion is accidental and
due to misunderstanding the argument or is
intentional and aimed at making it easier to
refute. Either way, one commits the straw man
fallacy. - In other words, the attacker of a straw man
argument is refuting a position of his own
creation, not the position of someone else. The
refutation may appear to be a good one to someone
unfamiliar with the original argument.
51- Example on the Straw man fallacy
- Bill and Jill are arguing about cleaning out
their closets Jill "We should clean out the
closets. They are getting a bit messy."Â Bill
"Why, we just went through those closets last
year. Do we have to clean them out
everyday?"Â Jill "I never said anything about
cleaning them out every day. You just want too
keep all your junk forever, which is just
ridiculous. - 3. False Dilemma
- A False Dilemma is a fallacy in which a person
uses the following pattern of "reasoning" Â - Either claim X is true or claim Y is true (when X
and Y could both be false). - Claim Y is false.
- Therefore claim X is true.
- This line of "reasoning" is fallacious because if
both claims could be false, then it cannot be
inferred that one is true because the other is
false.
52Example on False Dilemma 1. Bill "Jill and I
both support having prayer in public
schools."Â 2. Jill "Hey, I never said that!"Â 3.
Bill "You're not an atheist are you
Jill? Example 2 1. Bill is dead or he is
alive. 2. Bill is not dead. 3. Therefore Bill is
alive.
53- 4. Appeal to Pity
- An Appeal to Pity is a fallacy in which a person
substitutes a claim intended to create pity for
evidence in an argument. Example You must
accept that 1146, after all I'm dying..."
While you may pity me because I am dying, it
would hardly make my claim true. - Example of a case in which a claim evokes pity
and also serves as legitimate evidence - Professor "You missed the midterm, Bill."
- Bill "I know. I think you should let me take the
makeup." - Professor "Why?"
- Bill "I was hit by a truck on the way to the
midterm. Since I had to go to the emergency room
with a broken leg, I think I am entitled to a
makeup." - Professor "I'm sorry about the leg, Bill. Of
course you can make it up."
54- 5. Burden of Proof (Argument from Ignorance)
- Burden of Proof is a fallacy in which the burden
of proof is placed on the wrong side. Another
version occurs when a lack of evidence for side A
is taken to be evidence for side B in cases in
which the burden of proof actually rests on side
B. A common name for this is an Appeal to
Ignorance. - As an example, in most cases the burden of proof
rests on those who claim something exists (such
as Bigfoot (Yeti), psychic (mental) powers,
universals, and sense data). - John "I think that some people have psychic
powers."Â Edward "What is your proof?"Â John
"No one has been able to prove that people do not
have psychic powers."
55- 6. Personal Attack
- A personal attack is committed when a person
substitutes abusive (rude) remarks for evidence
when attacking another person's claim or claims.
This line of "reasoning" is fallacious because
the attack is directed at the person making the
claim and not the claim itself. The truth value
of a claim is independent of the person making
the claim. After all, no matter how repugnant
(distasteful) an individual might be, he or she
can still make true claims. Â - In general, it is best to focus one's attention
on the content of the claim and not on who made
the claim. It is the content that determines the
truth of the claim and not the characteristics of
the person making the claim. -
- Dave says that we should pay our share of taxes
to the company. But he is untrustworthy, so it
must be wrong to do that.
56- 7. Poisoning the Well
- This sort of "reasoning" involves trying to
discredit (dishonor) what a person might later
claim by presenting unfavorable information (be
it true or false) about the person. This
"argument" has the following form  - Unfavorable information (be it true or false)
about person A is presented. - Therefore any claims person A makes will be
false. - - Example Don't listen to him, he's fake.
57- 8. Diverting the Attention (Evading the Issue)
- This type of fallacy occurs when the person does
not have a valid proof for his/ her argument, or
if he/she does not wish to present the
information in hand. - The person diverts his opponent attention and
moves to another topic. This diversion could be
very smooth and involve interesting topics that
most of times people do not notice it.
58Rules of Presenting a Convincing Argument
- 1. Respect your opponent and the opinions of
others, remember always that respect generates
respect and disrespect generates disrespect. - 2. Understand your opponent opinions/ points of
view, and identify their strengths as well as
weaknesses. Strive to be fair-minded in
evaluating all points of view. - Â
- 3. All reasoning leads somewhere or has
implications and consequences, Trace the
implications and consequences that follow from
your reasoning. Search for negative as well as
positive implications. Consider all possible
consequences Â
59- 4. Respecting diversity of culture, socioeconomic
variations, take into account the feelings,
beliefs, and thoughts of other people. - 5. Have a positive direction. Dont argue against
a certain view point if you cant offer an
alternative for it. - Â
- 6. Do not deny facts associated with certain
arguments, even if these facts may weaken your
position. Search for information that opposes
your position as well as information that
supports it. Make sure that all information used
is clear, accurate, and relevant to the
question at issue.
60- 7. Admit strong points in your opponent
argument, this will increase your creditability.
Be open-minded seriously consider other points
of view and be willing to consider changing one's
own position. - 8. Do not exaggerate in presenting your
argument, people have short attention span. Few
strong arguments have more affect than long,
boring, and probably weak ones. - 9. Present suitable argument for your specific
audience. Be aware of your audiences interest to
be able to present a good argument. - 10. Do not use an argument unless you believe in
it and have sufficient evidence to do so.
Restrict your claims to those supported by the
data you have. Withhold judgment/argument when
the evidence and reasons are not sufficient to do
so.
