Unlike descriptive statements (e.g. "the average height in the US is X"), causal statements involve a comparison between what happened and what would have happened absent an intervention. The latter is unobservable in the real world, a fact that Holland & Rubin term "the fundamental problem of causal inference" (pg. 10).
A further distinction is between declarative or descriptive knowledge in contrast to prescriptive knowledge. Descriptive knowledge represents what the world is like. It describes and classifies what phenomena are there and in what relations they stand toward each other. It is interested in what is true independently of what people want.
Descriptive science is a category of science that involves descriptive research; that is, observing, recording, describing, and classifying phenomena.Descriptive research is sometimes contrasted with hypothesis-driven research, which is focused on testing a particular hypothesis by means of experimentation.
Causal inference is the process of determining the independent, actual effect of a particular phenomenon that is a component of a larger system. The main difference between causal inference and inference of association is that causal inference analyzes the response of an effect variable when a cause of the effect variable is changed.
The most common decision problems are basic database-query-like questions like instance checking (is a particular instance (member of an ABox) a member of a given concept) and relation checking (does a relation/role hold between two instances, in other words does a have property b), and the more global-database-questions like subsumption (is a ...
Causal analysis is the field of experimental design and statistics pertaining to establishing cause and effect. [1] Typically it involves establishing four elements: correlation, sequence in time (that is, causes must occur before their proposed effect), a plausible physical or information-theoretical mechanism for an observed effect to follow from a possible cause, and eliminating the ...

Causal theories of reference were born partially in response to the widespread acceptance of Russellian descriptive theories. Russell found that certain logical contradictions could be avoided if names were considered disguised definite descriptions (a similar view is often attributed to Gottlob Frege, mostly on the strength of a footnoted comment in "On Sense and Reference", although many ...
