normative
Describing how things should be, based on rules or values.
Normative describes something that sets a standard or tells people how things should be, rather than just describing how things are. Think of the difference between observing that most students finish their homework at night versus saying students should finish their homework at night. The first is just a fact; the second is normative because it expresses a rule or expectation about proper behavior.
In discussions and arguments, normative statements express values and judgments. “Everyone deserves a fair chance” is a normative claim about what's right. “The average temperature in July is 85 degrees” is not normative: it's simply factual. Normative questions ask “What should we do?” or “What's the right way?” rather than “What is happening?” or “What exists?”
You'll encounter normative thinking everywhere: rules about classroom behavior are normative, advice about good sportsmanship is normative, and debates about fair solutions to problems involve normative reasoning. Scientists try to separate normative beliefs from factual observations, though it's not always easy. When someone says “That's just your normative view,” they mean you're expressing what you think should happen based on your values, not stating an objective fact that everyone must accept.
Understanding the difference between normative claims and factual ones helps you think more clearly about arguments and recognize when people are debating values versus debating facts.
