Inference is a step we make in our minds based on input received from our senses: the police car with flashing lights behind me wants me to pull over. Assumptions are presumptions we make based on experiences in the past. Because we have experience with them, assumptions are often believed to be true, even though they may not be justified: I believe police cars use flashing lights to get drivers’ attention.
Distinguishing between inference and assumption is sometimes difficult to do, but it’s an important first step in the process of critical thinking. This short article on inference vs. assumption is written by the same authors that wrote the Guide to Critical Thinking. As you read, consider the examples they chose (walking around a big city and seeing someone lying in a gutter). Then construct a three-part example of your own, taking into account:
- Situation
- Inference
- Assumption
Come up with two good examples to share with your class. Consider also whether or not you are justified in your assumption and what evidence it would take to change your assumption.
