Argument Fallacies

Fallacies in Argumentation
   A fallacy is an assertion that is stated sloppily or with the intent to sell an idea deceptively.  Some fallacies occur when the writer has simply (out of laziness or an arrogant bias) not researched the idea well enough.  Some understanding of these defective ways of reasoning is important for writers. They should avoid using them.  It is important that citizens understand them so they will learn to recognize faulty or deceptive reasoning. 
   Argument is often complex and occurs in many different contexts.  There are some argumentative contexts in which fallacies are less frowned upon than others.  We need to be able to identify fallacies, but we should be cautious in jumping to conclusions about them.  Rather than thinking of them as errors, you find and use to discredit an arguer or to rebut in a debate.  You might think of them as barriers to common ground and understanding, since they so often shut off rather than encourage debate.
   What follows are some of the more prevalent fallacies. 
  • Either/Or fallacy: This fallacy occurs when a speaker or writer presents the audience with two false choices: "Either this or that."  Not everything in the world is right or wrong, black or white, good or evil, democratic or undemocratic, and so on.  There are, of course, several issues and ideas that do involve precisely two realities--one is either pregnant or one is not--but other times an either/or statement fails to account for all possibilities in a given situation.  Those who commit this fallacy fail to account for the complexity of an idea, sometimes purposely, in order to force adherence to an agenda.  
  • Faulty (or hasty) generalization:  One engages in a faulty generalization when the scope of the evidence is too small or the quality of it is too poor to support the conclusion.  In his only trip by car through St. Louis, Joe witnesses the aftermath of the worst car wreck (involving several vehicles and injuries) he's seen in his life.  If, upon arriving home, Joe concludes that St. Louis is the most dangerous city in the U.S. in which to drive, he has committed a hasty generalization.  In order to justify such a claim, one would probably need to consult reliable, recent data on automobile accident rates in U.S. metropolitan areas. 
  • After this, therefore because of this: This fallacy assumes that a time relationship is the same as a causal one, that precedence is indistinguishable from cause.  One of the most common (albeit light) instances of this fallacy occurs when one complains that a rainstorm occurs because one has just washed his car.  Similarly, the claim that a sharp sales increase in a brand of computers is due to the buying public's fondness for a company spokesperson on TV may well be an instance of a post hoc, ergo propter hoc fallacy.  Some amount of credible research would be required to determine the veracity of such a claim.
  • Begging the question: This occurs when one makes assumptions about an argument’s truthfulness, or when a claim carries an idea that is itself questionable.  For example, the question-assertion, "What has led to the current breakdown in the morals of contemporary society?" This begs two questions:  1. "In what ways, by what standards, have morals 'broken down' in society?" 2. "How do you know; how can you measure and confirm this?"  Some assertions ("Reading and writing improve one's mind.") are self-evident, but others ("Schools are more violent now than ever before.") are not, and they must be proven.
  • Argument ad hominem: This phrase means "to the man" and is one of the most common fallacies in public today.  To commit an ad hominem fallacy (or attack) is to criticize someone not on the substance of what he or she says but on the personality of the person who says it.  In other words, to attack someone ad hominem is to attack that person's character.  Of course, character can have relevance to an argument, but when such an attack is used to cloud the issue and distract from rational discourse, one is committing an ad hominem fallacy.  When actors and musicians are criticized for having opinions about social or political issues ("He doesn't know what he's talking about.  After all, he's a singer, not political analyst"), it won't do to simply dismiss their remarks because they are "mere entertainers."  Talk radio and tabloid-style media largely thrive on the ad hominem attack.  Careful thinkers will spot and denounce such tactics as invalid and, in some cases, reprehensible.
  • Argument ad populum: Meaning "to the people," this fallacy (similar to the ad hominem attack) occurs when one appeals to peoples' irrational fears and prejudices as a way of preventing them from directly facing issues.  So, if someone from Hong Kong says to another Hong Konger, "That speaker is full of nonsense.  He is a Northerner," he is relying on an attitude, a shared suspicion of a certain group of people. Another way of committing an ad populum fallacy is by employing connotative terms to stir the emotions of a certain group of people.  Words such as "patriotic" and "pro-family" stir emotions for some audiences, while words such as "socialism" and "feminist" are often used to stir up irrational anger.  People who think for themselves question the use of such words and phrases as ready-made codes about how and what to think. For example, one might argue that patriotism is, of course, a good thing, but that real patriots have an obligation to question authority and to reject the notion of "My country, right or wrong" as dangerous, totalitarian rubbish.                       
  • The Red Herring: This strangely-titled fallacy, named after a strong-smelling fish (the scent of which throws hounds off the scent of a trail), occurs when one draws attention away from the main issue in a given case by focusing on a side issue or on something irrelevant.  Accused of deceptive accounting practices, some in a major accounting firm replied that their practices are the norm in all accounting firms.  This claim may or may not be true, but it is a red herring because it attempts to draw fire away from the accounting firm and toward the larger profession of accountants.  Another way to see the red herring is as a changing of the subject.
  • Non-sequitur: Latin for "it does not follow," a non sequitur is an inference that doesn't follow from the premises.  In a sense, every fallacy is a non sequitur, an attempt to pass off two or more ideas as related though they are in fact not related (e.g., "If we can send a man to the moon, why can't we find a cure for the common cold?").
  • The appeal to traditional wisdom justifies something by stating, "We've always done it that way."  
  • A strawman fallacy occurs when one changes an opponent's argument, often by focusing on a weakened version of the argument (e.g., "My opponent wants to free serial killers and kidnappers, but I believe in laws that favor the rights of victims").  A straw man is, of course, easier to dissemble than a real man.
  • The bandwagon appeal suggests that a great movement is underway and makes the reader feel guilty or foolish if he or she has not become a part of it (e.g., "Over 60% of the city's residents believes he is a doing a satisfactory job as police chief, so your unfavorable opinion of him is discredited.")

Script of 2 TV Crime Reports

Crime Report 1: Mugging
Reporter: I’m standing here at the scene of an attack that took place at half-past nine this morning. An elderly lady was on her way to the shop to buy groceries when she was confronted by a young man. He produced a knife and threatened to hurt her if she didn’t give him her handbag. The lady called for help, but the man pushed her to the floor and pulled the bag out of her hands. He then ran away before help could arrive. The victim was shaken by the incident, but was not seriously hurt. She described the man as being in his late teens or early twenties. He wore blue jeans, white trainers and a black jacket with a hood that was pulled over his head. Police are looking for anyone who may have been in the area at the time to come forward.

Crime Report 2: Bicycle Theft
Reporter: Local news now, and police are said to be baffled by a spate of bicycle thefts on Lamma Island. Over the previous three nights, a total of twelve bikes have been stolen from outside houses in Yung Shue Wan. All of the bikes had wheel-locks fitted or were chained to railings, but it appears that the thieves were able to cut through these security devices. Police have conducted a thorough sweep of the island and found no evidence of the stolen vehicles. It is thought that this is the work of a gang with access to a boat, which they are using to take the bicycles off Lam ma to be sold elsewhere. Police are asking for Lamma residents to get in contact with them if they have seen any suspicious activity in the last few days.

Notes on Survey Report Writing

Notes on Survey Report Writing

  • “Survey” = questions and answers; “Report” = your writing, telling what you learned, analyzing, and making recommendations
  • You should give your essay a title. Since a survey report is a very practical, factual piece of writing, it should have the topic and basic information “in a nutshell”.
  • The words of a title should all begin in caps, except for conjunctions and prepositions. (See the article referred to, below.)The title should be in the center of the page, and if it helps, underline each word and use bold to set it off from the rest of the writing.  E.g.,
             Report on a Survey of Consumer Attitudes
  • “medium” ß singular;   “media” ß plural; e.g., “There are two media we should use: the Internet and TV.  One medium will not be enough.”
  • The topic (or subject) of this writing was not mobile phones.  The topic was: a survey on consumer attitudes towards advertising.  Your Introduction should have stated this.
  • “find” means: to look for something; “find out”, a phrasal verb, means: to learn something new.  They have different meanings and uses.  E.g., “I cannot find my pen”; “We want to find the best way to advertise”; “When did you find out you had to do this writing?”; “We want to find out if TV is a better way of advertising than the Internet”.
  • Use correct indentation to guide the reader’s eye to the section or subsection that he wants to read.  Most readers of writing like a survey report do not want to begin “at the top”.  They want to be able to quickly find and read the information that is most important to them.  Numbering convention:
