Reading isn't just about understanding the words on the page. It's about understanding what isn't there. Professional and academic texts rarely spell everything out. Authors expect you to connect the dots, to read between the lines. This skill is called inferential reasoning. It's the process of using textual evidence and your own background knowledge to uncover the author's unstated meaning.

Think of yourself as a detective. The text provides the clues, but you have to piece them together to solve the puzzle of the author's full argument. A writer might state that a company's profits doubled after a new CEO took over. The literal meaning is clear. But the implied meaning, the inference, is that the new CEO's leadership was responsible for the growth. The author didn't say it directly, but the connection is strongly suggested.

Every argument is built on a foundation of assumptions, or premises. Sometimes these are stated explicitly, but often they are implicit. Identifying these hidden premises is the first step to truly understanding and evaluating an argument. An implicit premise is a belief or assumption that the author takes for granted and expects the reader to share.

For example, a report might argue, "To increase public safety, we must increase police patrols in the city center." This argument rests on an unstated, or implicit, premise: that a greater police presence directly causes a decrease in crime. As a critical reader, your job is to spot that assumption. Is it valid? Is there evidence to support it? Asking these questions helps you move from passively accepting information to actively analyzing it.

This process involves a form of reasoning called abductive reasoning, where you work backward from an observation to form the most likely explanation. You see the author's conclusion, and you infer the unstated belief that must be true for the conclusion to hold up.

Another example: An academic paper states, "The study's reliance on self-reported data from participants is a significant limitation." The implicit premise here is that self-reported data is inherently less reliable than objectively measured data. The author doesn't need to explain this; it's an assumed standard within scientific research. Recognizing this allows you to understand the critique's depth and context.
