3.11 Using Visual Elements to Strengthen Arguments

Adding visual elements to a persuasive argument can often strengthen its persuasive effect. There are two main types of visual elements: quantitative visuals and qualitative visuals.

Quantitative visuals present data graphically. They allow the audience to see statistics spatially. The purpose of using quantitative visuals is to make logical appeals to the audience. An appeal based on logic is called “logos,” and it persuades the reader using reasoning. Often we can provide information in data form to persuade the reader through logic. Quantitative visuals help display the information clearly. For example, sometimes it is easier to understand the disparity in certain statistics if you can see how the disparity looks graphically. Bar graphs, pie charts, Venn diagrams, histograms, and line graphs are all ways of presenting quantitative data in spatial dimensions.

Qualitative visuals present images that appeal to the audience’s emotions. Persuading your reader based on an emotional appeal is called “pathos.” Photographs and pictorial images are examples of qualitative visuals that can create an emotional appeal. Such images often try to convey a story, and seeing an actual example can carry more power than hearing or reading about the example. For example, one image of a child suffering from malnutrition will likely have more of an emotional impact than pages dedicated to describing that same condition in writing.

Writing a Persuasive Essay

Choose a topic that you feel passionate about. If your instructor requires you to write about a specific topic, approach the subject from an angle that interests you. Begin your essay with an engaging introduction. Your thesis should typically appear somewhere in your introduction. Be sure to have a clear thesis that states your position and previews the main points your essay will address.

Start by acknowledging and explaining points of view that may conflict with your own to build credibility and trust with your audience. Also state the limits of your argument. This too helps you sound more reasonable and honest to those who may naturally be inclined to disagree with your view. By respectfully acknowledging opposing arguments and conceding limitations to your own view, you set a measured and responsible tone for the essay.

Make your appeals in support of your thesis by using sound, credible evidence. Use a balance of facts and opinions from a wide range of sources, such as scientific studies, expert testimony, statistics, and personal anecdotes. Each piece of evidence should be fully explained and clearly stated.

Make sure that your style and tone are appropriate for your subject and audience. Tailor your language and word choice to these two factors, while still being true to your own voice. Finally, write a conclusion that effectively summarizes the main argument and reinforces your thesis.
