Critical thinking enables you to be a more independent reader and writer. The most important task of a writer is to effectively and accurately transmit information. When you use critical thinking about what you have read and what you want to say to other readers, you are able to distance yourself from whatever feelings that you experience when you read that information. You are able to stay objective. This is important because you need to try to keep your writing free of bias. When you are presenting material to others, you must always question your sources as well as the methods they use. Critical readers understand that how material is presented is as important as the material itself. Although a certain amount of bias may be unavoidable, a critical thinker will strive to identify all biases so that information can be put into context. A critical thinker needs to analyze written material. Some ways you can do this are: by restating a text; by describing different aspects of a text; and by interpreting a text through assigning meaning and value to the text as a whole.
The written material is the evidence through which the reader can recognize bias, by studying the language used and the content that is chosen by the author. A critical thinker can search for patterns within language and content that set the persuasive tone for the material. As a reader and a writer, you should learn about your sources. You should learn about the time, the place and the occasion of all writings, and you should gain an understanding of the intended audience. These are all factors in determining whether rhetorical devices are used prejudicially.
An author's motives for writing the material should also be analyzed at the outset. These motives will help a critical thinker to focus on the reasons why he is reading and/or writing the material. Is the material pertinent? Is it likely to be useful? When a person processes information that has been read in a critical way, that person is more likely to transmit it through his own writing in an unbiased fashion. There will then be less distortion of the original information when it is presented to others. A writer should use critical thinking to accurately present all the facts and to logically analyze them.
