Writing for busy readers: six principles for effective communication

Executive overview

Most writing fails before it's read. The default response to any message is to not read it. Todd Rogers, co-author of Writing for Busy Readers, shows — through 50–80 randomised experiments — that shorter, simpler, structured writing consistently outperforms longer writing at getting responses, sign-ups, and action.

The framework applies user design thinking to writing: if the reader skims, misses the point, or gives up, that is the writer's failure, not the reader's.

Writers who take full responsibility for reader comprehension communicate more effectively, reach more people, and earn more responses.

The six principles

1. Less is more — fewer words, fewer ideas, fewer requests. Cutting a message in half consistently produces more responses. Adding more reduces the chance anyone reads any of it.

2. Make reading easy — use short, familiar words and short sentences. 50% of US adults read at a ninth-grade level or below; complex language excludes them and fatigues everyone else. Simple writing is more accessible and more likely to be read.

3. Design for easy navigation — write for scanners and skimmers, not close readers. Use headings every two paragraphs; in one experiment this more than doubled click-through past the second paragraph. A wall of text is daunting; structure makes it navigable.

4. Use enough formatting, but no more — bold, underline, and highlight signal "most important content." Readers jump to formatted text and skip the rest. One formatting type works; multiple types confuse. Highlighting five things is as effective as highlighting nothing.

5. Tell readers why they should care — surface what matters to the reader, not the writer. Airbnb's IPO email used legal jargon in the subject line; hosts who could have gained pre-IPO shares likely ignored it. A subject like "Early access to Airbnb shares" would have worked.

6. Make responding easy — reduce friction, reduce steps, pre-populate where possible. Engagement drops steeply at each stage: seeing the message, opening it, reading it, acting on it. Remove every obstacle between reader and action.

Writing and editing

Writing serves two functions: clarifying your own thinking, and transferring an idea from writer to reader. These are distinct. The draft that helps you figure out what you think is not what you share.

• Add a final editing pass with one question: how do I make this easier for the reader?
• "It was in there" is not a defence — if the reader didn't get it, that is on the writer.
• Context determines application; a 70-page CIA intelligence report can't be shortened but still benefits from better formatting, clearer structure, and an unambiguous call to action.

AI and the principles

ChatGPT is trained on well-written prose, not on effective writing for busy readers. It produces coherent paragraphs — not scannable, skimmable content.

• Rogers and co-author Jessica Lasky-Fink trained GPT-4 on the six principles and tuned it on pre/post email rewrites.
• The free tool at writingforbusyreaders.com restructures emails into headers, bullets, and condensed text.
• Useful as a teaching tool: paste a draft, see the transformation, reverse-engineer what changed and why.
• The AI output is a starting point, not a final draft.
