Hello World

All models are wrong, but some are useful.

A model is a simplified representation of something real. Usually, it’s a complex idea distilled into a simpler framing.

The purpose of a model is to simplify (through representation) so that the original thing being modeled is easier to understand or explain. Through this simplification, the model preserves what is relevant to its purpose, which means that everything else is intentionally omitted.

This is not a design flaw, but rather a design decision. Every simplification is an intentional choice that determines the utility of the model. This means that models can reveal one aspect of reality, but not the whole picture.

A model gains its usefulness precisely because it leaves things out.
