Social proof, as the analysis uses the term: the post shows that other people — customers, peers, numbers of them — already did the thing or believed it. 285 posts in the library lean on it, and they reach a median of 633 likes against the library's 632.

What it travels with

Social proof rarely works alone. In these posts it most often appears beside specificity (285 of 285) and reciprocity (14). The opening that carries it most often is an observation — 150 of the 285.

How to use it without faking it

The mechanism is a description of why something worked, not an instruction to manufacture the effect. The post shows that other people — customers, peers, numbers of them — already did the thing or believed it — so the question to ask of a draft is whether that is actually true of it, not whether it sounds like it is. The posts above pass that test; the library's rejected ones mostly did not.

From the analysis of the strongest example: Preserve the Hook → Landing structure and the plain observation opening. Replace the subject matter entirely with the writer’s own product, story and numbers.
