AI Content & Publishing Market: Why People Mistake Em-Dashes for AI Writing

Storytelling Edge's newsletter explores why readers increasingly associate em-dashes and polished prose with AI-generated writing. It references a Wired story on a growing 'anti-AI literary counterculture' in which writers avoid AI conventions like negative parallelism and deliberately introduce small mistakes to signal human authorship. The piece cites an Economist study showing ChatGPT now rarely uses em-dashes, while Claude still uses them more than human writers. Linguist Gretchen McCulloch explains the linguistic concept of enregisterment, linking the em-dash's stigma to learned associations rather than measurable overuse by AI. The newsletter also discusses Substack's AI-detection feature built with Pangram, citing University of Chicago and UPenn studies that claim over 99% accuracy, and notes Pangram CEO Max Sperro's unclaimed $100 bounty for false positives. The author concludes that writers should develop a distinct personal voice rather than simply avoiding AI tells.
