I think part of the problem here is that "high-density UIs" gets used in multiple ways. Some designers, perhaps not those with ready access to users, take high-density UIs to refer to the markings on the screen. A button with borders next to a text field with borders is considered to be higher density than a button without borders next to a text field without borders, because the borders visually divide the field up. And if the border lines provide an affordance (e.g. a button pushed up), then that's complexity (because the lines have different colors, which is more complex than a design where lines all have the same color).

But such an interpretation goes against the research of the 80s and 90s. I have never been directed to evidence that "complexity" and "density" refer specifically to visual complexity and visual density as distinct from conceptual complexity and conceptual density or widget complexity and widget density - all the evidence I've ever come across (as in the old evidence, or the medium post by another descendant comment of my parent comment) suggests that visual complexity and density actually operate to clarify conceptual/widget complexity/density.

So I think the claims made by practitioners need to inspected and made more precise. What kind of complexity and density are they trying to resolve? And what evidence do they have that this specific kind of complexity and density is problematic, rather than clarifying?
