The world is a complex place. The only way to deal with it is is to simply - to create abstractions, or as I would say, to identify and recognize patterns in the phenomena. When we teach, we often take the short-cut of teaching these simplifications directly, rather than having students identify and recognize them for themselves. This may be more efficient - there’s no shortage of studies that show this - but each time we teach a simplification, we make it harder for students to recognize new or alternative patterns in the same phenomena. But complex phenomena are dynamic, changing, and the simplifications are rarely valid for long.
