Persuasive Fallacies Chp 17
Persuading for a change to an existing law, plan, or policy, or for creating a new policy
Policy suggestions need to be real and sincere and based on evidence
Ex:
Asking what should be done to make a given situation better
Citizens handing out pamphlets on Election Day
When someone tries to persuade another person if a fact is true or not or that something did not did not happen
Convince the audience that what you are proposing is correct
Examples:
The captain of the Titanic was solely responsible for the ship’s untimely sinking
Texting while driving is a dangerous habit
Use when trying to persuade the relative merits - good/bad, moral/immoral - of a position
Focus on judging what is right or wrong or on what is good or bad
Use of pathos (emotional appeal)
Ex:
Pharmaceutical companies have the moral responsibility not to test their products on animals
It is not moral that poverty exists in the United States
Speaker Credibility comes from:
Knowledge of topic
Personal experience or connection with topic
Personal interest in & attitude about topic
Professionalism, vocal and physical delivery
Personableness, sincerity, enthusiasm
Being prepared, rehearsed and display confidence
Verifying facts to be credible and trustworthy
Ask for a suspended judgment: Acknowledge the audience’s beliefs or opinions (opposing viewpoint(s), but at the same time politely ask them to consider your position on the topic.
Avoiding fallacies in reasoning.
Adding supporting facts/stories/evidence and reasoning (Use examples, comparisons and definitions).
Inductive: Someone makes specific observations and then draws a general conclusion. When you’re using inductive reasoning, correct observations won’t necessarily lead you to a correct general conclusion.
Examples:
Every quiz has been easy. Therefore, the test will be easy.
The teacher used PPT in the last few classes. Therefore, the teacher will use PPT tomorrow.
Deductive: A specific conclusion follows a general theory. When you’re using deductive reasoning, your conclusion will be correct if all the statements you say are correct.
Examples:
All students in this class play guitar. Sam is a student of this class. → Therefore, Sam plays guitar.
At the conference, all the people present are thirty or older. Maria is in the room. → Therefore, Maria is at least thirty.
Use specific EXAMPLES to support a larger claim
Examples specific to daily lives and relatable to the audience
Inductive Reasoning: If Socrates is a man and all men are mortal, then Socrates must be mortal as well.
Deductive Reasoning: I was bit by a German Shepherd when I was young, therefore most German Shepherds must be bitter.
BUT, avoid the hasty generalization with deductive reasoning.
Compares different ideas or examples to reach a conclusion literally or metaphorically
Ex:
“That relationship is like a bad sitcom.”
The argument is based on the audience’s understanding of the comparison
Concludes that if something is true for one case, it is true for another similar case
Often used with propositions of policy
Monroe’s Motivated Sequence Pattern
1. Attention
Make audience aware of problem and why it matters
2. Need
Elaborate on the need to address the topic
3. Satisfaction
Propose a solution to the problem
4. Visualization
Show audience what they will gain
5. Action
Ask audience to act on your proposal
A fallacy is basically an error in judgment or reasoning
This results in invalid conclusions and a speaker losing credibility.
Discussing an issue as if there are only two alternatives
This fallacy ignores any other possible alternatives
Example:
We either ban hairspray or the world will end.
The “Either-Or” Fallacy is also known as the false dilemma fallacy
“After this, therefore because of this”
Assuming that because two things happened, the first one caused the second one
Example:
Every time my brother Bill uses hairspray, it is an extremely hot day.
Ad hominem - TO THE MAN! - instead of addressing the important topic at hand with facts you instead attack (or praise) the person
Name-calling
Mudslinging
Personal attack
“Poisoning the well”
Ethos
The person’s character is attacked
The person’s circumstances are noted
The person does not practice what is preached
“Attacking the person”
Three forms of Ad hominem: abusive, circumstantial, tu quoque
Identify the attack and show that the character or circumstances of the person has nothing to do with the truth or falsity of the proposition being defended.
Ad Verecundiam (appeal to authority) - while sometimes it may be appropriate to cite an authority to support a point, often it is not. In particular, an appeal to authority is inappropriate if:
The authority is not an expert in the field
Experts in the field disagree on this issue
The authority was joking, drunk, or in some other way not being serious
Hearsay
Show that either the person cited is not an authority in the field, or that there is general disagreement among the experts in the field on this point.
Slippery Slope - exaggerates the consequences of an action, usually to frighten readers
A chain of events
Focuses primarily on results or outcomes
INTO THE FUTURE
Illegitimate use of the ‘if-then’ operator
Identify the proposition P being refuted and identify the final event in the series of events. Then show that this final event need not occur as a consequence of P.
The Domino Theory
Non sequitur - ‘it does not follow’ - connecting two topics that don’t have any connection based of assumptions
Several steps are missing in between
Strawman - refutes a person’s actual position and substitutes a distorted, exaggerated or misrepresented version of that position
A diversionary tactic that sets up another’s position in a way that can be easily rejected
The author attacks an argument different from (and weaker than) the opposition’s best argument
Show that the opposition’s argument has been misrepresented by showing that the opposition has a stronger argument. Describe the stronger argument.
The Straw Person
Hasty Generalization - is an argument that draws interference from insufficient evidence
Someone draws a conclusion about a population based on a sample size that’s not large enough
A broad claim based on a few occurrences
The sample is too small to support an inductive generalization about a population
Identify the size of the sample and the size of the population, then show that the sample size is too small. Note: a formal proof would require a mathematical calculation. This is the subject of probability theory. For now, you must rely on common sense.
Overgeneralization
Either-or Fallacy/Polarization/False dilemma
Either-or Fallacy - only two options exist in a complex situation
Black/White Fallacy
Polarization - exaggerates positions and groups by representing them as extreme and divisive
False dilemma - ‘Either this or that’
Aka ‘excluded middle’
Illegitimate use of the ‘or’ operator
Logos
(False cause) Post hoc - ‘one event caused another to happen’
A occurred, then B occurs; therefore, A causes B.
Look for time relationships (IN THE PAST)
Often superstitions are post hoc fallacies.
Coincidental Correlation, ‘too much of a coincidence’ argument
Show that the correlation is coincidental by showing that the effect would have occurred even if the cause did not occur, or that the effect was caused by something other than the suggested cause.
Red herring - uses irrelevance to distract attention from the real issue
The basic idea is to “win” an argument by leading attention away from the argument and on to another topic.
Begging the question - repeating the same thing as if it is the reason
(circular reasoning)
The truth of the conclusion is assumed by the premises. Often, the conclusion is simply restated in the premises in a slightly different form. In more difficult cases, the premise is a consequence of the conclusion.
Petitio principii
Show that in order to believe that the premises are true we must already agree that the conclusion is true.
Appeal to Pity (or sympathy) - creating a “guilt trip”; the reader is persuaded to agree by sympathy
Ad miscercodiam
The reader is told to agree to the proposition because of the pitiful state of the author.
Identify the proposition and the appeal to pity and argue that the pitiful state of the arguer has nothing to do with the truth of the proposition.
‘Root for the underdog’ regardless of the issues at hand
Pathos
Playing to Emotions
This allows manipulators to avoid responsibility for something
Appeal to Tradition - ‘if it ain’t broke, don’t fix it’
‘Because that’s how it’s always been done’
Common sense
Might an alternative policy work better?
Have circumstances changed over time?
Are there drawbacks to the long-standing policy?
Bandwagon - ‘everyone’ supposedly thinks or does something, it must be right.
‘Everyone else is doing it/believes it.’
Fear of being ‘left out’
Popularity/quantity with quality
Aka ‘Ad populum’, ‘appeal to the crowd’, ‘appeal to popularity’, ‘appeal to emotion’, ‘appeal to popular passions’, ‘argument from common sense’, ‘lying with statistics’
Emotional appeals often sway the population as a whole
The manipulator shares the same views as the audience
Persuading for a change to an existing law, plan, or policy, or for creating a new policy
Policy suggestions need to be real and sincere and based on evidence
