When I think about a system that makes zero assumptions, I imagine it would have a large number of configuration points, where every single aspect of behavior and interaction must be specified explicitly instead of implicit and assumed. That sounds complex.

On the flip side, a counter-example comes to mind: automatic imports ("autoloading") in some languages, which makes things apparently simple but gets gnarly when things break unexpectedly. It makes a lot of assumptions about your intention, which is simpler when it works the way you expect. I'd prefer explicit imports every time, even if it's verbose (some might call "complex") because it makes no assumptions - every import is visible so it's actually simpler to understand.
