# Style and Formatting Patterns Patterns betraying AI-generated text through visual and structural form, not content. Detection tools use these markers as high-confidence signals. --- ### 1. Em-Dash Cascade **Problem:** AI uses 15-25 em-dashes per medium text. Humans use 2-3, and generally prefer commas, periods, or parentheses for most functions AI assigns to em-dashes. **Before (AI):** > The project — which started in 2022 — brought impressive results — especially in the data area — and is now being expanded — even with limited budget — to other regions. **After (human):** > The project started in 2022 and brought solid results in data. It's now expanding to other regions, even with a tight budget. **Detection signals:** - More than 2 em-dashes per paragraph - Em-dash where comma resolves - Chaining of parenthetical asides with em-dashes (— X — Y — Z) - Text where >10% of punctuation marks are em-dashes **Correction techniques:** - **Limit of 2 em-dashes per paragraph** - convert extras to commas, periods, or parentheses - Differentiate use: em-dash for strong contrast, parentheses for side comment, comma for light aside - "Editor test" - if a human editor would have cut the em-dash, cut it --- ### 2. Excessive Bold **Problem:** AI applies bold to every keyword as if the text were a slide deck. Running text with bold on every important noun reads like a product catalog, not human writing. **Before (AI):** > The **platform** offers **native integration** with leading **CRMs**, ensuring **scalability** and **security** for **sales** and **marketing** teams. **After (human):** > The platform integrates with the major CRMs. Works well for sales and marketing teams that need to scale without losing access control. **Detection signals:** - Bold on more than 1-2 terms per paragraph - Bold on common nouns (platform, team, result) without editorial reason - Bold used as substitute for good sentence structure - Text where >5% of words are bolded **Correction techniques:** - **Limit of 1-2 bolds per section** - never per paragraph - Use bold only for **intentional contrast**: "The problem isn't the tool - it's the **process**" - If bold is compensating for lack of clarity, **restructure the sentence** instead - "Print test" - if text looks like it was formatted for a reader with ADHD, bold is excessive --- ### 3. List-ification (Bullet Point Abuse) **Problem:** AI converts prose into bullet points at every opportunity. Three sentences of flowing text become a bulleted list with "Key takeaways:" above it. Human writing uses lists sparingly - for actual enumerations, not for every paragraph. **Before (AI):** > Here are the key benefits: > - **Increased efficiency** - Teams work 40% faster > - **Improved collaboration** - Cross-functional alignment > - **Better outcomes** - Measurable ROI improvements > - **Scalability** - Grows with your organization **After (human):** > Teams work faster with it - about 40% based on our internal tracking. The real win is cross-functional alignment though: people who never talked to each other before are now in the same workflow. **Detection signals:** - Bulleted lists that could be flowing prose - "Key takeaways:" / "Key points:" / "Here's what you need to know:" above lists - Parallel structure in every bullet (same length, same construction) - Lists with 5+ items where 3 would suffice **Correction techniques:** - If items are truly discrete enumerable things (steps, features, names), keep as list - If items are connected thoughts, convert to prose paragraphs - Break bullet symmetry: vary length, mix sentence fragments with full sentences - "Would I say this aloud as a list?" test - if you'd narrate it, it's prose --- ### 4. Header Proliferation **Problem:** AI creates a `##` header for every 2-3 paragraphs in any text longer than 400 words. Human prose flows continuously - headers appear when genuinely changing topic, not every 150 words. **Before (AI):** > ## Introduction > The problem is clear. > ## Background > Here's context. > ## Current Situation > Things have changed. > ## Analysis > Let's examine this. > ## Conclusion > In summary... **After (human):** > The problem is clear - and it's been getting worse since 2023. [continues flowing for 800 words with maybe one section break where the topic genuinely shifts] **Detection signals:** - Headers every 100-200 words in what should be continuous prose - Generic headers: "Introduction", "Background", "Analysis", "Conclusion" - Headers that just restate what the next paragraph says - Document with 8+ headers for 1000 words --- ### 5. Emoji Inflation **Problem:** AI (especially ChatGPT) injects emoji into every bullet point, section header, or list item. Human writers use emoji occasionally and contextually, not systematically. **Before (AI):** > 🚀 Key Features > ✅ Automated deployment > 💡 Smart suggestions > 🔒 Enterprise security > ⚡ Lightning-fast performance **After (human):** > The main features: automated deployment, smart suggestions, enterprise-grade security, and good performance. (It handles 10k requests/second on our benchmark.) **Detection signals:** - Emoji on every list item - Emoji in headers - More than 2 emoji per 500 words in professional text - Systematic emoji (same emoji category repeated: all checkmarks, all rockets) **Correction techniques:** - Professional context: remove all emoji unless the format genuinely calls for them (social posts, chat) - Social context: keep 1-2 per post, used for emphasis or tone, not decoration - Never use emoji as bullet point markers in serious writing
