An inference is a generalization or deduction that we make about the behavior of a particular person or thing. Inference can be based on observed behavior, or on information that we believe to be true. Inference can be logical or factual, and it can be based on what we know about the person or thing, or on what we think might be true.

Inference can be an important part of our day-to-day lives. We use inference to make predictions about the behavior of other people and things, and to come to conclusions about the facts of a situation. For example, we might infer that someone is angry based on his facial expression, or that a product is defective based on the number of complaints that have been filed.

Inference is an important tool that we can use to make sense of the world around us.
