Lesson Transcript
Instructor: Amy Troolin

Amy has MA degrees in History, English, and Theology. She has taught college English and religious education classes and currently works as a freelance writer.

In this lesson, we will define and learn how to recognize biases, assumptions and stereotypes in written works. We will also practice identifying these elements with a few writing samples.

Biases, Assumptions, and Stereotypes

They're sneaky. They're common. They show up in many different kinds of writing from many different kinds of authors. They try to make their way into your brain and change the way you feel about people or things. They're biases, assumptions, and stereotypes, and part of being an effective reader is recognizing these devious little devices and thinking about them critically. This lesson will help you learn how to do that.


Let's start with biases. What is a bias? Bias occurs when a writer displays a partiality for or prejudice against someone, something, or some idea. Sometimes biases are readily identifiable in direct statements. Other times a writer's choice of words, selection of facts or examples, or tone of voice reveals his or her biases.

We all have biases that reflect our opinions and our particular outlooks about life. That is perfectly normal and simply part of being human. Therefore, nearly every piece of writing exhibits some sort of bias. A reader's job is to recognize biases and think critically about them to determine how much they affect a writer's presentation of his or her subject.

Recognizing biases takes practice. As you read, ask yourself the following questions to help you identify biases:

  • Does the writer use overly positive or overly negative language about the subject?
  • Does the writer use emotionally charged language about the subject?
  • Does the writer use vague or generalized language about the subject?
  • Does the writer omit any important facts?
  • Does the writer add information and evidence that seems unnecessary just to bolster his or her point?
  • Does the writer fail to properly cite his or her sources?

If you've answered 'yes' to any of these questions, you can be pretty sure that the writer has some sort of bias toward the subject. Now let's practice. See if you can pick out the writer's bias in the following sample.

'Cats and dogs can both make good pets. Dogs can be affectionate, but they are extremely difficult to care for. Cats, on the other hand, are also very lovable, cuddly animals, and they require only moderate care that isn't too time consuming.'

Take a closer look at the writer's choice of words. Which animal does the writer prefer? Cats or dogs? If you said cats, you are correct, and you have just identified a bias!


Let's move on to the next sneaky little device: assumptions. Assumptions are points in an argument that a writer takes for granted and doesn't prove with evidence. We all make assumptions everyday based on our experience, culture, education and beliefs, and assumptions are present in every piece of writing. In fact, assumptions can be very good things because they provide common ground between writers and readers and free a writer from having to prove every point he or she makes.

Readers do, however, have to be conscious that assumptions exist and make an effort to identify them and think critically about whether or not they are valid. To recognize assumptions in a piece of writing, first identify the writer's claim. What is the writer trying to prove? What does he or she want readers to accept? Now think about the reasons and evidence the writer presents to support his or her claim. Finally, reflect on what the writer has left unsaid or taken for granted about his or her argument, those ideas that hover in the background and must be accepted if the argument is to work. Those are the assumptions.

Let's practice with a couple samples. Here's the first:

'I simply refuse to vote for a candidate who does not live a good, moral life. Congressman Smith has been accused of being involved in several romantic affairs, so his opponent will get my vote.'

The writer is claiming that she will vote for Congressman Smith's opponent. Why? The Congressman has been accused of being involved in several romantic affairs and, therefore, does not live a good, moral life. Now think about what the writer has left unsaid. What is she assuming? She assumes that politicians need to be morally upright personally to do their jobs properly, that the accusations against Congressman Smith are true, and that the opponent does live a good, moral life. Let's try another.

'Anyone interested in high-speed, high-quality, reasonably priced printing should purchase one of the latest models of Precision Printers. They come with everything that will meet all your printing needs.'
