* If a large majority in a particular reference group G accepts A as true (false), then there exists a defeasible presumption in favor of (against) A * A large majority accepts A as true (false). * Therefore, there exists a presumption in favor of (against) A This form of the argument might use polls or statistics meant to measure public opinion. This argument may or may not accurately reflect a real world state, but the fact that so many people commit to it, gives it a presumption that it does accurately reflect a real world state. (Walton, Reed, Macagno. 125) Critical Questions regarding the argument scheme. 1. Is it really the case that a large majority of the particular reference group accepts A as true? 2. Is there any other available evidence that would support the assumption that A is false? 3. What reason is there for thinking that the view of this large majority is likely to be right? |
On the left is a picture of a type of argument diagram. Douglas N. Walton uses the araucaria program, but I don't use it as much as I use this type of form mixed with flowcharting conventions by hand. I use the software sometimes, but I mostly do diagrams using the tools I already know. Here are a couple of links to PDF Documents by Walton explaining what diagramming arguments is good for.

Depending on preferred classification style, it can be a subcategory of Ad Populum or a subcategory of Source-based Arguments. Ad Populum arguments are inherently weak and prone to exploit prejudice. They are typically categorized as fallacies but in many instances they can be reasonable arguments and the best kind of evidence available to make a rational decision (Walton, Reed, Macagno. 121). |
Major Premise: a person a is in a position to know about things in the domain of a subject which contains proposition P. Minor Premise: a asserts that P is true (or false). Conclusion: P is true (or false). Critical Questions about the argument 1. Is a in a position to know whether P is true (or false)? 2. Is a an honest (trustworthy, reliable) source? 3. Did a assert that P is true (or false)? Reference for this example in the book Argumentation Schemes Douglas Walton, Legal Argumentation and Evidence.

Explanation Information that is supposed to indicate the origin, cause, meaning, or significance of an event or other phenomenon.
Example: "She's the best tennis player on the team because she has had better coaching, is in better shape, and practices a lot more than anyone else"
Argument Information that is supposed to establish that a proposition is true or otherwise worthy of belief or acceptance.
Example: "She consistently defeats all her teammates, so she's the best tennis player on the team."
