Questions about Cognitive Load
More than someone needs to make the decision the page exists for. Volume is not the problem; irrelevance is. A dense page where everything serves one choice can feel lighter than a sparse page where half the elements are unrelated.
Only when it separates things that were competing. Space between unrelated groups helps; space inside a group that should read as one unit makes the reader work harder to connect it. Load comes from relationships being unclear, not from density itself.
