Persuasive Writing

Some notes to help you prepare your ’sales pitch’ for your novels.

The Basic Principles of Persuasive Writing

Persuasive writing is writing that sets out to influence or change an audience’s thoughts or actions.

We are subjected to persuasion everyday from the time we wake up until the time we go to bed. When you turn on and listen to the radio, read the papers or watch the television. different groups of people are trying to persuade you about something.

Whenever you buy a product or use a service, your choice has likely been influenced by a persuasive marketing ad. There are, of course, many occupations where persuasion is a skill used on an everyday basis. Lawyers, teachers, clergy members, and journalists are just a few.

The point is that understanding persuasive strategies can help you in two very important ways:

1) Knowing the strategies helps you analyse the strategies other people are using to persuade you. This way you can protect yourself when, for example, unethical marketers are trying to take advantage of you.

2) Knowing the strategies helps you to choose which is the most effective way to persuade an audience.


How do we get others to accept our point of view?

  1. by appealing to their reason
  2. by appealing to their emotions
  3. by the appeal of our good character

1) Appealing to Reason:

Remember that an argument is an appeal to a person’s sense of reason; it is not a violent fight, dispute, or disagreement. It is a measured, logical way of trying to persuade others to agree with you.

One critical thing to remember that there are at least two sides to every issue. If you take the attitude that there is only one side–your side–you will quite likely alienate your reader.

You need, then, to choose one side of an issue clearly in an effort to persuade others. If you’re unsure of your own stance, how can you expect other people to assess, understand, and be convinced by your position?

Example:

Issue: Should my father stop smoking?

Position: Yes

Questions you may ask (Your reasoning skills often depend on what we call “common sense”):

Ask yourself the following questions:

  • Do I have enough evidence? (Is it sufficient?)
  • Will my audience believe my evidence? (Is it trustworthy?)
  • What are the assumptions built into my argument, and are those assumptions fair? (Is it verifiable?)
  • Does my conclusion follow logically from the claims I make?

There are two basic types of reasoning processes: Deduction and Induction

DEDUCTION: begins with a general principle or premise and draws a specific conclusion from it.

ex. All people who smoke endanger their health. (major premise)

My father smokes. (minor premise)

Therefore, my father is endangering her health. (conclusion)

Is this a strong argument?

  • you need to offer evidence in support of your claims
  • it may be impossible to prove a cause-effect link between my father’s smoking and his declining health

Other issues you may bring in to support your argument:

  • 2nd hand smoke / impact on family and friends
  • the staggering number of people over 60 years old who die from lung cancer

INDUCTION: supports a general conclusion by examining specific facts or cases.

Ex. If I was to argue that my father was endangering his health, I might cite specific symptoms:

  • His teeth are yellowish and he’s lost a considerable amount of weight.
  • He’s no longer able to cycle his 25km every morning.
  • Whenever he exerts himself physically, he ends up coughing extremely hard.

Other Logical Appeals?

You could cite smoking/cancer statistics, authority in the form of the Surgeon General, financial costs etc…

2) Appealing to Emotion:

The logical appeal is certainly an extremely persuasive tool. However, our human nature also lets us be influenced by our emotions.

One way of evoking emotion in your reader is to use vivid images.

Ex. (to my father who smokes): “I remember when Grandma died of lung cancer. It was the first time I had ever seen you cry Dad. I remember that you also made me promise not to start smoking.”

You could also offer vivid examples in support of your argument. Use language and/or images that are emotionally charged:

  • You might detail the pain of going through chemo therapy.
  • You could use Xrays of diseased lungs, or photos of cancerous gums.

Be careful, however, that when you use emotional appeal, you use it “legitimately.” You should not use it as a substitute for logical and/or ethical appeals. Don’t use emotional appeals to draw on stereotypes or manipulate our emotional fears. Don’t use emotional appeal to get an automatic, knee-jerk reaction from someone. If you use emotionally charged language or examples simply to upset or anger an audience, you are using emotion illegitimately. Your use of emotional appeal shouldn’t oversimplify a complicated issue.

3) Appealing to our good character:

The appeal of your ethics can occur on one or more of the following levels in any given argument:

  1. Are you a reasonable person? (That is, are you willing to listen, compromise, concede points?)
  2. Are you authoritative? (Are you experienced and/or knowledgeable in the field you are arguing in?)
  3. Are you an ethical/moral person (Is what you’re arguing for ethically sound/morally right)
  4. Are you concerned for the well-being of your audience? (To what extent will you benefit as a result of arguing from your particular position?)

The ethical appeal is based on the audience’s perception of the speaker. Therefore, the audience must trust the speaker in order to accept the arguments. Don’t overlook ethical appeal, as it can be the most effective of the three.


Elements of a Good Argument:

Remember to identify any unfamiliar or uniquely used terms in your argument.

If you forget to define your terms (or choose not to define them) you run the risk of alienating your audience, confusing them, or causing them to come to inappropriate conclusions.

For example, before making the argument that teachers should “monitor” their students, the word monitor should be defined. Does “monitor” include eavesdropping on their group discussions? Does it include accessing their registrar’s files to see how well (or how poorly) the students are doing in their other classes? Does it mean reading their e-mail in an online course without their knowledge? You would want to be clear about such a term so that someone wouldn’t misinterpret its usage in a particular context.

You Must Ensure that Your Evidence is Convincing:

Convincing evidence will satisfy the following questions:

  • Is the evidence sufficient in volume? That is, is there is enough evidence to present a strong, indisputable case.
  • Is the evidence trustworthy? Does it come from reliable, informed sources.
  • Is the evidence verifiable? That is, can you corroborate it through other sources. Is the evidence factual, or does it rest solely on opinion?

Appeal to authority:

If you are drawing on an authoritative, expert figure to back up what you say, is the authority actually reliable? When trying to determine whether someone is an authority, consider the following elements:

  1. Is your expert a current authority on the specific subject in question?
  2. Is your expert up-to-date on the most current procedures, statistics, testing programmes etc.
  3. Is your expert viewed favourably by their peers? Is he/she respected in the field?
  4. Is your expert associated with reputable organizations?
  5. Is your expert as free of bias as possible?

Remember that when quoting a source you must be careful that you don’t accidentally (or intentionally) take the quote out of context, changing the original meaning.

Keep in mind, as well, that your authority should be knowledgeable about the subject; he/she should not simply be someone famous. A celebrity endorsement is not quite the same as expert opinion (unless the celebrity is endorsing a product that she/he uses.)

Canadian Olympic snowboarder Ross Rebagliati may be an expert when it comes to endorsing snowboard wax, but he’s not necessarily an expert when asked about the national unity debate. Bryan Adams’ celebrity status does not make his an expert authority on the national economy, but he would be a reliable, trustworthy source if you asked him about building recording studios.

In addition, you want to ensure that the authority you are using is still current in the field. For example, you might not want to use a long-retired politician like Pierre Trudeau as your focus expert on the state of the unity issue in Canada today.

Remember that the most successful arguments often combine the three appeals. With that in mind, be very careful about relying solely on logic in an argument. Use a combination of appeals to allow for a more balanced argument. An audience may readily become resistant to your argument if you rest solely on a particular line of reasoning that they fundamentally disagree with.

Improper Evaluation of Statistics:

Using statistics, studies and surveys can be very persuasive if they are used ethically and accurately.

Ask yourself the following questions before using this kind of evidence:

  1. Were the survey questions as objective as possible?
  2. Was the sample pool representative or biased?
  3. Are the statistics accurately tabulated?
  4. Have the statistics been taken out of context?
  5. Is there enough context provided so that the reader gets a clear view of any pre-existing bias?

Another way of looking at it

Bringing About Change

Persuasive speakers plan to secure behavioural changes in their listeners by influencing thinking and motivating action. Persuasive speakers attempt to modify their listeners’ attitudes and values, and alter their listeners’ beliefs. Attitudes, values, and beliefs are interconnected, but differ in their meanings.

Organizing for Persuasive Speaking

Choosing a Topic

Students should keep the following three guidelines in mind when they are selecting a topic for their persuasive speech. Good topics are:

  • controversial
  • clear
  • supported by evidence.

Stating the Proposition

Your proposition must be in the form of a declarative sentence which states a claim. There are four general types of propositions: propositions of fact, value, policy, and definition.

A fact claim is a statement about how things were in the past, how they are in the present, or how they will be in the future. A fact claim is not a fact; it only claims to be a fact. What makes it arguable is that the speaker has no direct way of establishing the truth of the claim. For example, “The Earth is round” is a proven fact. “In our right-handed world, left-handed people are discriminated against” is a fact claim. A persuasive speaker must provide arguments which build a case in favour of the claim, showing that the claim is probably true, or at least is more likely true than false.

Value claims are arguable statements concerning the relative merits of something which is measured subjectively (e.g., “Victoria is a better place to go for summer vacation than Calgary”). What makes a value claim arguable is that different people may disagree on the criteria used to evaluate something (e.g., weather, live entertainment, water sports). Differing value claims may be used to argue the value of a variety of topics (e.g., movies, styles of living, community organizations). Defending a value claim involves offering a set of criteria for consideration, defending the set of criteria as legitimate, and showing how applying the criteria justifies the claim.

A policy claim is a statement regarding the merits of one course of action as opposed to other courses of action. What makes a policy claim arguable is that, even though people and institutions may not be totally certain about the proper course of action to take, they still must act. To argue in defence of a policy claim is to state that, given the knowledge we have at the present time, it is best to act in the manner proposed rather than in some alternative way.

A definition claim is a statement telling how a particular word or phrase should be defined in a certain context. A definition claim is arguable because different people use the same word in contradictory ways. Therefore, the claims made by different people may also be contradictory, when these claims are based on their own special interpretations of word usage and meaning.

Principles of Persuasion

Students should keep the following principles in mind when they are preparing persuasive speeches:

  • People are more likely to change their behaviour if the proposition asks for a small change rather than a large change in their lives (e.g., trying one vegetarian meal rather than becoming total vegetarians).
  • People are more likely to consider changing their behaviour if the change will benefit them more than it will cost them. Consider the costs to the audience in terms of money, time commitment, energy, and skill.
  • People are more likely to change their behaviour if the change meets their needs. Needs vary in different communities, in different schools, and in different individuals.
  • People are more likely to change their behaviour if suggested change is approached gradually in the talk. Move from arguments which the audience will find most acceptable to those which the audience will find more difficult to accept.

Using Persuasive Strategies

Three basic strategies used in persuasion are appeal to reason, appeal to audience emotion, and appeal to audience needs. Speakers should remember their ethical responsibilities and not use dishonest or misleading persuasive appeals.

Listening Critically to Persuasive Speaking

The critical listener raises certain questions concerning the meaning of what is said and the intention of the speaker. The critical listener analyzes the persuasive speech, yet withholds judgement until there is enough data for drawing conclusions. Some questions the critical listener might ask include:

  • What is this speaker’s goal?
  • Is the problem as important as this speaker says it is?
  • Is there enough evidence presented to justify an acceptance of the speaker’s claim?
  • Are there pieces of evidence or arguments which have not been introduced?
  • Has the speaker provided sources for the data which is presented?
  • Does the speaker cover up the main issue through the use of less important examples or details?
  • Is the speaker sincere?
  • Are the speaker’s arguments logical?
  • Has the speaker tried to manipulate me by appealing to certain emotions or needs that I have?

Listeners will add questions or change them to suit their own purposes and needs, depending on the uniqueness of each persuasive talk.

    Mr Grosse,
    I have some questions about the ERP Project:
    1) What are the important points we have to write about the book?
    ~E.g. Target audience, theme, ect.
    2) How long must the speech be?
    3) Do we HAVE to use symbols? If I use symbols, do I put it in a presentation slide or just print out the pictures?
    Thanks,
    Yu Teng

  2.   Cassandra says:

    Mr Grosse,
    the example on the smoking…
    it is true right?
    If it is… THAT MEANS I REALLY IMPROVED IN MY
    S.S. PORTFOLIO!

    I did on smoking too..
    and the target audience was: teen smokers.
    and i did add in most of the examples that was stated.
    that’s a really good improvement (:

    also,
    #1 The persuasive speech, it can be on any book right? Since we are the ones recommending the book, it is on the assumption we read it, therefore we can state things like: This book has a great and interesting beginning and ending. The beginning draws attention …………..

    It is okay for us to state that right? And we can also draw up examples from it like: When i read it, i really felt as if i was surrounded by sand, and i could really picture Camp Green Lake. …..

    it is okay to cite examples, i think.
    please see this comment… (:

  3.   Isaac says:

    hm, interesting, I need to get started!!!!!!

  4.   Melissa says:

    Mr Grosse, when we are doing the presentation, do we take the position of a reader?

  5.   williamgrosse says:

    You are a representative/agent who wants to ensure that the book is published. You have the purpose – persuading a board at a publishing house/firm to publish the book; the audience – CEO and board members of Scholastic and finally the context- delivering a speech/presentation to persuade them.

    Speech should not be more than 3-4 minutes.
    Will provide handouts to clarify on Monday.

  6.   Zera says:

    Mr. Grosse, Just like to check, we are assuming that this book has not been published yet right? So, can we say that you should publish this book as it is very popular and give statistics on the number of people who have read this book? ( Personally I don’t think so but I’m not sure. So…just to confirm. )

  7.   williamgrosse says:

    You should treat the book as if it had not been published before, so not stats about readership etc

  8.   Zi Bing says:

    Mr Grosse, can we “make up” some stats eg. pretend that we did a survey on certain groups of people, letting them read the book, and the feedback was positive?

  9.   Cassandra says:

    you did mention that you would provide handouts… i don’t think you gave it out. Did you?

  10.   bowei says:

    Does the book have to be published by Scholastic

  11.   bowei ('(..)') click on URL for Funny Video says:

    and How long does the speech have to be? I really need some guidelines…=(

  12.   jekkee says:

    Mr Grosse, here are some questions and difficult to understand words/phrases/paragraphs that I encountered while reading the text.

    I did not understand this paragraph. What does it mean?:
    “Be careful, however, that when you use emotional appeal, you use it “legitimately.” You should not use it as a substitute for logical and/or ethical appeals. Don’t use emotional appeals to draw on stereotypes or manipulate our emotional fears. Don’t use emotional appeal to get an automatic, knee-jerk reaction from someone. If you use emotionally charged language or examples simply to upset or anger an audience, you are using emotion illegitimately. Your use of emotional appeal shouldn’t oversimplify a complicated issue.”

    In: 3) Appealing to our good character, what does “Don’t overlook ethical appeal, as it can be the most effective of the three.” mean?
    What is ethical appeal?

    When you wrote: the most effective of the three, are you refering to all of these:
    1. Appealing to reason
    2. Appealing to emotion
    3. Appealing to good character

    What does a proposition mean?

    I did not understand the paragraph on policy claims. Maybe it was because I was not so used to the topic: policy claims and its relevant topics.

    Mr Grosse, when must we present our speech? Are we just going to have a script and a book?

  13.   jekkee says:

    Mr Grosse, can we make use of the fact that Scholastic is a leading children’s book publisher?

  14.   jekkee says:

    Can we also make use of the fact that Scholastic has produced best-sellers like harry potter?

  15.   bowei ('(..)') click on URL for Funny Video says:

    Mr Grosse, is there a minumum length for the speech? I’m still confused about how you start the speech

  16.   bowei ('(..)') click on URL for Funny Video says:

    How do we appeal to someone else’s good character when we do not even know what it is?

  17.   Zi Bing says:

    Mr Grosse, are we allowed to “copy” from the reviews done by other people, for example, I found a review online about the book I’m doing on, and it says “…. is about the price of peace, both personal and political, and what we knowingly destroy in our hope of achieving that, be it friends, democracy or ourselves” , so can I put that in my speech without mentioning the review and make it seem to be my “own”, because if the book is supposedly not published, it cannot have reviews yet.

  18.   williamgrosse says:

    You can use words/phrases etc you like but please do not ‘copy’ the review wholesale.

  19.   williamgrosse says:

    Begin with a bang, your strongest argument .
    The audience must be made to listen to you. Make us interested in what you have to say!

  20.   bowei ('(..)') click on URL for Funny Video says:

    Mr Grosse, I have another question: How do we address you? Do we say Mr Grosse or Scholastics CEO etc.

  21.   Isaac says:

    we call him Mr. Grosse, The usual

  22.   bowei ('(..)') click on URL for Funny Video says:

    Do we have to bring the book?
    - TO Isaac -> are u sure? some ppl said scholastics CEO…i think i’ll wait 4 Mr Grosse to reply

    *i think i lost ‘A Wrinkle in Time’ =(

  23.   williamgrosse says:

    There is no need to bring the book. How can you bring a book when its is not supposed to have been published!

  24.   williamgrosse says:

    Call me by my name! Mr Grosse

  25.   bowei ('(..)') click on URL for Funny Video says:

    oh ok

  26.   jekkee says:

    Mr Grosse, is this our last ERP assignment?

  27.   Gary says:

    How many do we even have?

  28.   jekkee says:

    Serriously, I don’t know. Perhaps even Mr Grosse have no idea either. (Maybe he lost count)
