Language Tells
- •"Here's what I learned"

- •"Sometimes [X] is the best [Y]"
- •Overuse of "leverage," "impact," "scale"
Emotional Arc
- •Crisis → Struggle → Lesson → Success
- •Vulnerability without specifics
- •Perfect narrative arc (too clean)
- •Generic relatability hooks
Research Finding
54% of LinkedIn long-form posts analyzed in 2024 showed strong AI signatures. The platform's algorithm appears to favor the predictable engagement patterns of AI-generated content, creating a feedback loop where formulaic posts outperform authentic, idiosyncratic human writing.
