  • Deductively invalid, inductively weak argument.
  •  Error:
    1. Structural fallacies (fallacies of denying the antecedent)
    – Analyze:
    If you drink pepsi then you will look cool (A), active and creative like Ha Anh Tuan and Phuong Linh (B)
    You don’t drink pepsi (Not A)
    Therefore you couldn’t look cool, active and creative (Not B)
    2. Content fallacies (fallacy of presumption – Fallacy of Relevance)
    – Analyze: it is the fact that Ha Anh Tuan and Phuong Linh look cool but it is irrelevant to drinking pepsi. People can also look cool without drinking pepsi but by other ways.

Item 2:

Công ty tôi trang bị đồng phục cho nhân viên bằng áo sơ mi của một thương hiệu tốt trong nước, nhưng sau khi dùng 1-2 lần chúng tôi vô cùng thất vọng, vải thì xuống màu, luôn nhăn nheo mặc dù giá gần 300.000 đồng/cái.

Cũng trang bị cho văn phòng, Công ty chúng tôi mua ghế ngồi cho nhân viên, nhưng xài được 2 tháng, cái thì xì nhớt, cái thì gãy bánh xe …

Qua những việc vừa nêu, tôi nghĩ chất lượng hàng Việt rất kém.

  • Error:

Content fallacy: fallacy of presumption – hasty generalization (what is true for one or two members is true for the whole group)

– Analyze:

Premise 1: Đồng phục cho nhân viên dùng 1-2 lần thì vải xuống màu, nhăn nheo.

Premise 2: Ghế ngồi được 2 tháng thì bị xì nhớt, gãy bánh xe …

Conclusion: Chất lượng hàng Việt rất kém

Some Viet products, which the writer’s company used, have bad qualities. The writer concludes that all Viet products have bad qualities. (Hasty generalization)

Argument Structures and Fallacies

Item 1: Picture

Fallacy: post-hoc fallacy 

Analysis:

A happens

B happens after A

________________

A causes B

A brow bear told a white dog he was a poopy-head (means stupid, but can be understand literally as “somebody was hit in the head”). Right after that they saw a pig hit a turtle in the head, and the dog blamed the bear for his statement, thinking that was what caused the fight between the pig and the turtle. However, two events were irrelevant, the dog’s logic had post-hoc fallacy.

Item 2: Commercial

http://www.youtube.com/watch?v=7udQSHWpL88&feature=player_embedded

Fallacy: Slippery slope

Analysis :

A happens -> B

B -> C…-> N

_____________

A -> N

Cable company keeps on you hold -> you get angry -> go to gym -> accidence happens -> you get an eyes patch -> you look tough -> people want to see how touch you are -> you wake up in in a roadside ditch

Conclusion: get rid of cable if you don’t want to wake up in a roadside ditch

It’s clear that each step in the process is not the only event would happen, as well as isn’t really relevant, so the process is illogical. For example, not everyone who is angry goes to gym, or an accidence always involve eyes patch. In the end, there is no persuasive reason why people should get rid of cable, as the whole progress is unlikely to happen.

Item 3: Newspaper

Deciphering the racial codes on the movement’s ubiquitous placards does not require a doctorate in Semiotics. One popular sign shows the president’s face and a caption:“Undocumented worker.” Another features his image and a complaint: “The Zoo Has an African Lion and the White House Has a Lyin’ African!”

Source : http://www.huffingtonpost.com/richard-m-benjamin/why-the-tea-party-movemen_b_450897.html

Fallacy: ad hominem

It’s no doubt that the fallacy here is ad hominem, as the signs are nothing but tools to attack president Obama. They state him “Undocumented worker” and “Lying African”, which provides no logical reason for why they’re against him or whether Obama has done something wrong. They simply scapegoat the US’s president.

Argument Structure and Fallacies

 

ITEM 1

“I am going to tell you exactly what’s wrong. I am going to give you 4 tips that will turn things around. If you listen to my advice you WILL get big and strong. If you ignore my advice you will remain small and weak. It’s your choice. The following tips work. I know because I have used them myself to make rapid progress”.

Source: http://www.muscleandstrength.com/articles/four-big-reasons-still-small-weak.html

–> Structural fallacies: denying the antecedent

Analysis: 

     if A (you listen to my advice), then B  (you WILL get big and strong)

     not A (ignore my advice) 

     therefore not B (remain small and weak = not big and strong) 

 

ITEM 2:

“How are your Bowels?
 

In ancient times, people did not say “How do you do?” They said, “How are your bowels?” The ancients thought that the bowels were the seat of the emotions.  We find in the Bible, the expression -“Bowels of Compassion.”  Today the same writer would probably say -“Heart of Compassoin.” 

 

Source:  http://timriedel.wordpress.com/2011/11/10/vintage-ads-how-are-your-bowels/

–> Content fallacies: appeal to authority

Analysis: 

The advertiser tries to sway us by citing the Bible as an authority on the importance of bowels.   Today’s healthcare is far more effective than it was in biblical times as our current life expectancy is far greater than it was when the Bible was written.  

The disparity between ancient and modern life expectancy shows that the Bible possesses outdated information on healthcare, and thus is a weak authority on the bowels because of insufficient expertise.

ITEM 3

Here is the transcript from the clip:

LEO: What else?

C.J.:The Ryder Cup team is declining our invitation to come to the White House.

LEO: You’re kidding.

C.J.:Because of the joke.

BARTLET: You’re kidding.

C.J.: I’m not.

[Mrs. Landingham comes in and gives Bartlet his schedule.]

BARTLET: The Ryder Cup team?

C.J.: It’s a group of the best golfers in the country…

BARTLET: I know what the Ryder Cup team is. Thanks Mrs. Landingham.

C.J.: Sir, this may be a good time to talk about your sense of humor.

BARTLET: [looks at his schedule] I’ve got an intelligence briefing, a security briefing, and a 90-minute budget meeting all scheduled for the same 45 minutes. You sure this is a good time to talk about my sense of humor?

C.J.: No.

BARTLET: Me neither.

LEO: What else?

C.J.: It’s just that it’s not the first time it’s happened.

BARTLET: I know.

TOBY: She’s talking about Texas, sir.

BARTLET; I know.

C.J.: U.S.A. Today asks you why you don’t spend more time campaigning inTexas and you say it’s ‘cause you don’t look good in funny hats.

SAM: It was “big hats.”

C.J.: What difference does it make?

BARTLET: It makes a difference.

C.J.: The point is we got whomped in Texas.

JOSH: We got whomped in Texas twice.

C.J.: We got whomped in the primary, and we got whomped in November.

BARTLET: I think I was there.

C.J.: And it was avoidable, sir.

BARTLET: C.J., on your tombstone, it’s gonna read, “Post hoc, ergo propter hoc.”

C.J.: Okay, but none of my visitors are going to be able to understand mytombstone

BARTLET: Twenty-seven lawyers in the room, anybody know “post hoc, ergo propter hoc?” Josh?

JOSH: Uh, uh, post, after, after hoc, ergo, therefore, after hoc, therefore, something else hoc.

BARTLET: Thank you. Next?

JOSH: Uh, if I’d gotten more credit on the 443…

BARTLET: Leo?

LEO: After it, therefore because of it. [Josh, a little weirded out, looks]

BARTLET: After it, therefore because of it. It means one thing follows the other, therefore it was caused by the other, but it’s not always true. In fact, it’s hardly ever true. We did not lose Texas because of the hat joke. Do you know when we lost Texas?

C.J.: When you learned to speak Latin?

BARTLET: Go figure.

Translation
The banter which makes the West Wing such a great program gets in the way here, the main gist is this:

C.J.: The Ryder Cup team is declining our invitation to come to the White House.
Because of the joke.
Sir, this may be a good time to talk about your sense of humor.
It’s just that it’s not the first time it’s happened.

TOBY: She’s talking about Texas, sir.

C.J.: U.S.A. Today asks you why you don’t spend more time campaigning in Texas and you say it’s ‘cause you don’t look good in funny hats.
The point is we got whomped in Texas.
We got whomped in the primary, and we got whomped in November.
And it was avoidable, sir.

BARTLET: C.J., on your tombstone, it’s gonna read, Post hoc, ergo propter hoc – “after it, therefore because of it.”
It means one thing follows the other, therefore it was caused by the other, but it’s not always true. In fact, it’s hardly ever true.

 

–>Content fallacy: Post-hoc 

Analysis: 

In this video, character C.J. argues that because President Bartlet made a joke about Texan hats prior to two unsuccessful votes in Texas, it follows that the joke was the reason he lost the votes. Bartlet points out that this inference is fallacious because it assumes that if one thing follows another then the first thing caused the second; this assumption is a fallacy of logic. C.J.’s argument committed the post hoc fallacy.- After it, therefore, because of it – don’t simply assume that because one thing follows another, the first thing caused the second thing to happen

 

ENTRY 4_ DO MAI ANH

ITEM 1:

If all mammals have hair to cover their whole bodies, then birds are mammals. Birds have feathers to cover their whole bodies. Therefore, birds are mammals.  

=> Structural fallacy (affirming the consequent)

Analysis:

This is inferred from the argument below:

If A, then B

B

Therefore, A

This argument is invalid. Because mammals are defined in many features. Only by having hair to cover their whole bodies can not conclude that one creature (like bird) is a mammal.

ITEM 2:

http://www.youtube.com/watch?v=-23kmhc3P8U

=> Fall dilemma

Analysis:

As it can be interpreted through the video the idea of the false dilemma can be recognized that the former president of the USA posing false either/or choice: With us or against us. As he said “you are with us or you are with the enemy”, he reckoned that they are the only options in this situation. In fact, there are other possibilities, people might not support the USA but it does not mean they against the USA and be America’s enemy, they might be neutralist.

ITEM 3:

Image

=> Hasty generalization

Analysis:

This argument is invalid. There are many weightlifters and the author only met two of them. Therefore, the author do not have enough information to conclude that all weightlifters take steroids. It is only a false assumption.

-> Hasty generalization
Analysis:
This ad uses the logical fallacy of hasty generalizations to advertise its product as well as persuade buyers: Remember…”if you have skin, you need StriVectin”. The conclusion is based on the unconvincing evidence because product quality has not been tested by consumers in real and whether it is good enough or not as in advertising.

ITEM 2: Story
JOKE: TAKE A LOGICAL THINKING CLASS
Two rednecks decided that they weren’t going anywhere in life and thought they should go to college to get ahead…
The first went in to see the counselor, who recommended him to take history or logical thinking class.
“What’s logical thinking?” the first redneck asked.
The professor answered, “Let me give you an example. Do you own a weed eater?”
“I sure do.”
“Then I can assume, using logical thinking, that you have a yard,” replied the professor.
“That’s real good!” said the redneck.
The professor continued, “Logic will also tell me that since you have a yard, you also own a house.”
Impressed, the redneck said, “Amazing!”
“And since you own a house, logic dictates that you have a wife.”
“That’s Betty Mae! This is incredible!”
The redneck was catching on.
“Finally, since you have a wife, logically I can assume that you are heterosexual,” said the professor.
“You’re absolutely right! Why that’s the most fascinating thing I ever heard! I can’t wait to take that logical thinking class!”
The redneck, proud of the new world opening up to him, walked back into the hallway where his friend was still waiting.
“So what class are ya taking’?” asked the friend.
“logical thinking class!” replied the first redneck.
“What the hell is logical thinking?” asked his friend.
“Let me give you an example. Do ya own a weed eater?” asked the first redneck.
“No,” his friend replied.
“You’re gay, ain’t ya?”
Souce: http://www.m2woman.co.nz/read.php/article/joke-take-a-logical-thinking-class
-> Slippery slope
Analysis: In this story, fallacy is deductive chain of the professor, from assumption A to assumption B, C, D and jump to conclusion Z without any basis. No proof is given as to why ABC will happen. As a result, the first redneck also has give the wrong conclusion when he talks to his friend.

ITEM 3: News
Sticker in textbook reignites evolution debate
Ga. lawsuit challenges disclaimer stating subject is ‘theory, not fact’
updated 11/8/2004 3:56:32 PM ET
Print Font:
ATLANTA — A warning sticker in suburban Atlanta science textbooks that says evolution is “a theory, not a fact” was challenged in court Monday as an unlawful promotion of religion.
The disclaimer was adopted by Cobb County school officials in 2002 after hundreds of parents signed a petition criticizing the textbooks for treating evolution as fact without discussing alternate theories, including creationism.
“The religious views of some that contradict science cannot dictate curriculum,” American Civil Liberties Union attorney Maggie Garrett argued Monday before U.S. District Judge Clarence Cooper. The trial is expected to last several days.
But a lawyer for Cobb County schools, Linwood Gunn, held up a copy of a textbook’s table of contents Monday that showed dozens of pages about evolution.
“The sticker doesn’t exist independently of the 101 pages about evolution,” Gunn said. “This case is not about a sticker which has 33 words on it. … It’s about textbooks that say a lot more than that.”
The stickers read: “This textbook contains material on evolution. Evolution is a theory, not a fact, regarding the origin of living things. This material should be approached with an open mind, studied carefully and critically considered.”
One of the parents who filed the lawsuit, Jeffrey Selman, said the stickers discredit the science of evolution.
“It’s like saying everything that follows this sticker isn’t true,” he said.
The U.S. Supreme Court ruled in 1987 that creationism was a religious belief that could not be taught in public schools along with evolution.
Gunn said he expects the warning will hold up in court, saying it “provides a unique opportunity for critical thinking.”
“It doesn’t say anything about faith,” Gunn said. “It doesn’t say anything about religion.”
Souce: http://www.nbcnews.com/id/6434725/#.UZzaJLUVP8Y
-> Fallacies of Ambiguity: Equivocation
Analysis: In this example, this is a very well-known argument that evolution is just a theory – but everything in science is a theory. The debaters are finding equivocation about the scientific meaning between evolution and religion included in the textbook by the common something that is guesswork. In this case through textbook stickers.

ITEM 1:

The Perfect Son

 A: I have a perfect son

B: Does he smoke?

A: No, he doesn’t.

B: Does he drink whiskey?

A: No, he doesn’t.

B: Does he ever come home late?

A: No, he doesn’t.

B: I guess you really do have the perfect son. How old is he?

A: He will be six months old next Wednesday.

Source:

http://www.tienganh.com.vn/vi/modules.php?name=News&op=viewst&sid=5483

=> To B, she thinks A’s son who is not both smoking, drinking whiskey and coming home late is a perfect son.

Structure:

If A, then B
B
Therefore A
If a person is a perfect son, then he does not smoke, drink whiskey and come home late
He does not smoke, drink whiskey and come home late
Therefore, he is the perfect son (inference)

Fallacy : Affirming the consequent/ structural fallacy

This argument contains false inference “If a son doesn’t both smoke, drink whiskey and come home late, he is the perfect son”  because the perfect son doesn’t do that. And her son doesn’t do that so her son is perfect.

 

Item 2:

nobody-is-perfect-i-m-nobody-so-i-m-perfect

 

Link: http://www.keepcalm-o-matic.co.uk/p/nobody-is-perfect-i-m-nobody-so-i-m-perfect/

Verbal fallacy: Equivocation

The argument:

1. Nobody is perfect

2. I’m nobody

3. So, I’m perfect

Problem: The “nobody” in the first premise means ” no specific human being, no person ” while in the second premise, the word ” nobody ” is a metaphorical use to imply ” a person who is not popular or not widely known “.

Item 3:

Galileo affairhttp://en.wikipedia.org/wiki/Galileo_affair

Galileo before the Holy Office, by Joseph-Nicolas Robert-Fleury

Beginning around 1610, Galileo Galilei came into conflict with the Catholic Church over his support of Corpenican Astronomy.

In 1610, Galileo published his Sidereus Nuncius (Starry Messenger), describing the surprising observations that he had made with the new telexcope which promoted Heliocentrism (  the astronomical model in which the Earth and planets revolve around the Sun at the centre of Solar system )

The Roman Inquisition found this ” heretic ” and in February 1633, Galileo was brought before Inquisitor Vincenzo Maculani to be charged. Later , on June 22, the sentence of The Inquisitor was delivered:

” Galileo was found “vehemently suspect of heresy”, namely of having held the opinions that the Sun lies motionless at the centre of the universe, that the Earth is not at its centre and moves, as contrary to Holy Scripture.”

This argument is a Fallacy of irrelevant conclusion ( Appeal to authority ):

Claim of the Roman church : The Earth lies motionless at the centre with other planets, including the Sun, rotating around it.

Argument : Biblical references include text stating that  ”the Lord set the earth on its foundations; it can never be moved.” and  ”And the sun rises and sets and returns to its place”.

Problem: The Roman church ignored scientific evidences supporting Heliocentrism while defended the opposite just because the ” Holy Scripture stated that “. Thus, they gave a false judgement over Galileo and banned Heliocentrism despite astronomical knowledge and evidences ” in regard to theological truth “

Premise 1: my son had his vaccine

Premise 2: he developed autism

Conclusion: the vaccine caused autism

Weak argument: the premise is insufficient so the conclusion is wrong. There are many reasons to cause autism such as: bored, disappointed with something,…

Argument error: slippery slope.

Weak argument: the conclusion is wrong

Number is a general word for all numbers and each number has a different value, for example: 3,4,5,6,…

Item 3:

Trên thiên đàng, các nhà bác học nổi tiếng cùng nhau chơi trốn tìm. Sau khi oẳn tù tì thì Anhxtanh là người phải đi tìm. Anhxtanh mới đếm 1 …. 2 …. 3 … thì mọi người đã trốn hết, chỉ còn một mình Niu-tơn vẫn loay hoay không biết trốn vào đâu. Chợt… ông vẽ 1 hình vuông có diện tích 1m vuông và ngồi vào đó. Anhxtanh đếm đến 10, quay lại nhìn thấy Niu-tơn vội kêu: “Xì Niu-tơn!!! Xì Niu-tơn”. Niu-tơn liền nói: “Sai rồi, ta không phải Niu-tơn mà là Niu-tơn trên mét vuông [N/m2]. Phải gọi ta là Pascal!”

http://www.ued.edu.vn/khoaly/mod/glossary/view.php?id=51

(Premise 1- hidden): 1 Newton/= 1 Pascal

Premise 2: Newton is sitting in 1 square meter.

 

Conclusion: newton is Pascal

Argument error:  Equivocation

The argument is weak because the word “newton” in each premise refers a different meaning: Newton in “ N/” is an unit of measure while Newton is a person -> the conclusion is wrong.

ITEM 1: Fallacy in Article

Sourcehttp://pactiss.org/wp-content/uploads/2011/08/Vegetarians-linked-to-higher-brain-power.jpg

Image

 

–> Hasty Generalization

Analysis: The article drew a general conclusion from a sample that is biased. That the group of Mensa’s people who became vegetarian by 30 have higher IQ than average does not mean all people are smarter when they spurn meat. There are many factors that affect IQ of people, not only nutrition, but also social environment, education basis, gene, etc. Besides, Mensa is an international organization for people with very high scores in IQ tests, so it would be biased when they chose only people who already had higher intelligent basis for the research.

–> Slippery Slope

Analysis: The conclusion above is drawn from insufficient premises. If people have more knowledge of cars, why they will want a BMW? The author did not give any proof to prove that.

 

ITEM 3: http://www.youtube.com/watch?v=wZk8-enTyAo

–> Appeal to popularity

Analysis: This ad is fallacious in the way of suggesting audiences using Power TV simply because a lot of people in this video had it already. That a large number of people have something does not mean it is suitable and necessary for everyone else.

Thầy nào cũng phàn nàn không biết hình thù con voi nó ra làm sao.Chợt nghe người ta nói có voi đi qua, năm người chung nhau tiền biểu người quản tượng xin cho con voi đứng lại để cùng xem .Thầy sờ vòi, thầy sờ ngà, thầy sờ tai, thầy sờ chân, thầy thì sờ đuôi.

Ðoạn năm thầy ngồi lại bàn tán với nhau.

Thầy sờ vòi bảo:

– Tưởng con voi nó thế nào, hóa ra nó dài như con đỉa!

Thầy sờ ngà bảo:

– Không phải, nó cứng như cái đòn càn chứ!

Thầy sờ tai bảo:

– Ðâu có! Nó to bè bè như cái quạt thôi!

Thầy sờ chân cãi lại:

– Ai bảo? Nó sừng sững như cái cột nhà!

Thầy sờ đuôi lại nói:

– Các thầy nói không đúng cả. Chính nó tua tủa như cái chổi xể cùn.

Năm thầy, thầy nào cũng cho mình nói đúng, không ai chịu ai, thành ra xô xát, đánh nhau toạt máu đầu…

–         Fallacy of composition

–         Analysis: Since soothsayers are blind, thus they cannot see the elephant. However, they only touch a part of the elephant and say that it is elephant: “nó dài như con đỉa”, “nó cứng như cái đòn càn chứ”, “Nó to bè bè như cái quạt thôi!”, “Nó sừng sững như cái cột nhà” or “Chính nó tua tủa như cái chổi xể cùn.”

         Although trunk, ears, legs, tusks or tail are parts of the elephant, it is only                individual part, not whole elephant.

 

Item 2:

http://inkandvoice.com/wp-content/uploads/2012/10/Post-Hoc.jpg

Post – hoc fallacy

Analysis: This is an example of post- hoc fallacy which one tries to convince that event “2” occurred because of event “1”. Writer said that the reason of getting sick is a loaf of bread. Although he got cold after eating loaf bread, there is no relation between them. It is result from other reason.

Item 3:

Almost all fruits are edible raw food. Almost all edible raw food is full with dangerous bacterias. Therefore, almost all fruits are full with dangerous bacterias.    

Structural fallacy- Reasoning in a chain with almost all

Analysis: This is inferred from the following argument:

Almost all S are P.

 Almost all P are Q.

Therefore, almost all S are Q.

The argument is invalid. Because there is no evidence to prove that all fruits are full with dangerous bactaria. If the fruits are taken care of carefully, they will be fresh and harmless to human.

Analysis: a man whose donkey gets lost thinks that he did not sit on the donkey’s back, he did not lose  himself.

Structure fallacy:

If he sits on the donkey’s back, he will lose himself

He does not sit on the donkey’s back

Therefore, he does not lose himself

=> Denying the antecedence:

If A, then B

Not A

Therefore, not B

He still get lost because of many reasons such as he doesn’t know the way… so not because he sits on the donkey’s back, he will get lost.

               B: Is Iphone 5 expensive?

               A: Yes, of course. It is Apple!

               B: Ohhhh.He must be very rich.

  • Structure:

If you are rich, you can buy an Iphone 5.

He has an Iphone 5.

 
   

Hence, the boy is rich.

  • Analyst: Structural fallacies _ Affirming the consequent:

There are more than 1 reason that the boy can have an iphone 5 himself even he is not rich. He was gifted or won a contest, etc.
