Critically Evaluating Published Research and Opinion

In evaluating published research and opinion, two separate processes must take place. First, you must decide what you expect a particular work to accomplish for you. Then you must evaluate the work in hand and decide how well it accomplishes the desired task. To define your expectations, consider the following questions.

  1. What do you want the literature to do for you?

a. Familiarize you with a subject about which you know almost nothing?

b. Serve as evidence and “building blocks” for your argument?

c. Provide you with fresh approaches to a topic already familiar to you?

d. Tell you the latest developments in a field of scholarship you are already familiar with?

2. How much do you already know about this subject?

a. What general idea do you have of the subject?

b. Are you familiar with the names of prominent scholars and schools of thought?

c. Do you have definite opinions as to right and wrong in reference to this subject?

This should result in a statement of what you want the published research or opinion to do for you or tell you.

Now that you have an idea of what you want to accomplish, this guide in intended to provide you with a detailed list of questions for critically evaluating a published work, or published works of a particular discipline. Many of the points raised here may seem superfluous and too obvious to deserve mentioning, while other points may seem too detailed and probing to be done for every published work you may look at. Use your own judgment as to how much of this guide you wish to use at any one time — think of this guide as an idealized model for the type of evaluation you should be doing. By providing you with this framework, we hope to get you into the habit of considering all of these points when looking at an author’s work, and also when evaluating your own research.


The following questions will provide you with the basic information you need to identify your published work and make a preliminary decision as to its value to your research project.
