Which heading style is identified as a sign of AI writing?

• A. Title case headings
• B. All lowercase headings
• C. Bold-only headings
• D. Mixed-case headings

Answer: (A)

Title case headings are used as a clear, polished formatting choice that signals a professional, editor-style presentation. When major words in a heading are capitalized, it gives the text a clean, book-like look that AI writing tools often apply to make sections feel organized and formal. This consistent capitalizing pattern is recognizable and stands out as a deliberate editorial style, which is why it’s identified as a sign of AI writing in this context. For example, a heading like “Overview of AI Writing” uses title case and reads as a standard formal heading, whereas all lowercase headings (“overview of ai writing”) read as more casual or stylistic and are less diagnostic. Bold-only headings remove capitalization cues entirely, so they don’t provide the same editorial signal. Mixed-case headings — where capitalization is inconsistent — look irregular and aren’t typical of the steady formatting AI-generated text tends to aim for.
