Information Hierarchy

The reader should get the answer in the first thing they see, and find depth only when they reach for it. Everything else here follows from that: each beat of the piece takes the form that carries it best, what matters most comes first, and the medium stays as simple as the content allows.

Lead with the answer/conclusion

Readers scan. Open with the finding itself, and the piece works in thirty seconds. The same logic repeats at every scale: a section's first sentence is its answer, a slide's title is its takeaway ("Cache misses double p99" rather than "Performance"), a UI label carries its whole meaning alone.

Behind the answer sits depth (reasoning, evidence, edge cases), and behind that, sources. Keep depth that most readers will skip, and move it: a later section, a linked page, a footnote. Sources belong at the end.

Pick the form that fits the idea
