normative
Normative claims say how things ought to be or what someone should do. Descriptive claims say how things are. Ethics, political philosophy and much of epistemology deal in the first kind.
Why it matters
Noticing which kind of claim is on the table settles a lot of arguments that only look factual.
Also written: normativity
