Criticism - introduction

Criticism of the sources is

  • to evaluate the source critically
  • to evaluate the credibility
  • to find out who or what is the source
  • to establish the authenticity of the source
  • to check its information

Why evaluate critically?

The purpose of critical evaluation is to try to establish whether the source treats what it claims to treat, if it is relevant and reliable. You can begin by sorting your material from these criteria. Even though it might be difficult to get a clear answer for each item on the list, it is important though to evaluate your sources based on these criteria.

When you have sought information and found material it is time to evaluate what you have found critically. Does the material answer your questions? Is it enough, or do you need more information? Is it credible? In order to be able to establish this you must wear ”critical evaluation glasses”. Here are some issues you should consider when you check the credibility of your material.

  • Can you establish publisher and originator? Are they trustworthy?
  • Who is the author and what is his background?
  • Has the author published anything in that subject field before?
  • Has the publication gone through some kind of quality examination?
  • Is the information up-to-date? Information ages quickly in certain subject fields.
  • Are sources and references stated correctly? Do they refer to up-to-date and relevant literature?
  • Which is the main result? Is method and material accounted for?
  • Does the information contain facts or opinions? Is it the author’s own opinions which are presented or is it a compilation of other people’s thoughts.
  • What is the author’s purpose of the published information?
  • Do facts from different sources correspond?
  • Does the publication seem credible? What do others say about the publication? Are there any reviews?
  • Is this something you can use in your work?

The main rule that applies is that you should consider all information with critical judgment, and use common sense for the evaluation.
