Why it worked

Opens with a short, self-contained line that is easy to take in at a glance.
Uses concrete numbers instead of vague claims, which makes it credible and quotable.
Contradicts something the audience already believes, which stops the scroll.
Follows a clear Hook → Context → Context → Landing shape, so the reader always knows where they are.
Ends on a short line that is easy to quote and repeat.
The opening line stands alone, so it reads completely before the post is expanded.

The mechanics

Hook: Plain observation
Structure: Hook → Context → Context → Landing
