Welcome back to "Doggerel," where I ramble on about words and phrases that are misused, abused, or just plain meaningless.
This is one of the words that often comes in tune with fundamental misunderstandings of Occam's Razor. Occam's Razor is about minimizing the number of entities involved in a hypothesis. For example: Creationism versus evolution. You can summarize the former as "Magic Man Done It," but that doesn't make it simpler. Modern evolutionary theory deals with several demonstrable effects that we know exist, and can't be excluded because of that. For the standard Creationism, it requires introducing two new entities: The magic man, and some unspecified force that blocks the inevitable accumulation of all the effects evolution relies on.
Further, many woos love to claim whatever they believe in is simple and yet capable of complex behavior, like ghosts, spirits, deities, exotic energies, and so forth. This is only by fiat, and usually for convenience, since many of them need to believe in something magical, but don't want to have to take it apart to understand it. Of course, they usually lack evidence of the entity in the first place.
Another instance is an assumption that certain abstract ideas like art, morality, etcetera are simple, when they're often more complex than they think. This can sometimes be deflated by asking them simple questions, like for instance, "what's the definition of [key concept]?" Many concepts seem simple until you have to explain them.
