Whose data is it anyway? Using extrinsic proofs to persuade

Extrinsic proof, in short, is empirical evidence gathered by doing primary research (Crowley and Hawhee 200). So quantitative data (like statistics generated from surveys), artifacts, and first-hand accounts of events (like spoken, video, and audio testimonies) are all considered extrinsic proofs. The most important thing to keep in my when using extrinsic proofs is to be aware of the trustworthiness of your sources and to evaluate extrinsic evidence carefully.

Crowley and Hawhee offer the following process for evaluating extrinsic sources (208):

1. Cite your sources for every point where they might be misunderstood of contested.
2. Make sure your source actually supports or clarifies the point you’re making.
3. Comment on the source immediately, showing its relevance to your argument.

Let’s take a look together at the following examples of testimony, or first-hand accounts of an experience that is considered an extrinsic source.

What is happening in each video? How are these examples of The Guardian evaluating their extrinsic proofs?

HOMEWORK

Work on your Midterm and think about what you want to work on for The Persuasion Project.

I will not be assigning much writing homework between now and our midterm; instead, I will be giving points for class attendance and participation for in-class writing and activities. Our in-class work next week will be intended to help you make strides on The Persuasion Project. So, if you miss class between now and October 30th, you risk missing in-class writing points!
