Why the same content performs differently on two platforms
The file is identical; the ranking function is not. Each platform optimises a different behaviour, and the content is scored against that behaviour.

Intuition test — answer before you read on
Why does identical content reach very different audiences on two platforms?
Correct answer: B
Option A is partly true but the audiences overlap substantially. Option C matters at the margin, not by an order of magnitude. Creators demonstrably infer ranking criteria from fluctuating reach and reshape output around them, and ranking systems encode a specific designed definition of relevance rather than measuring interest neutrally.
The same eleven-minute video: forty thousand views in one place, two hundred in another, posted the same hour with the same title. Creators conclude one audience has better taste. The audiences overlap heavily. What differs is what each system was built to increase.
What everyone sees
Performance is treated as a property of the content, so identical content should perform comparably wherever attention exists. Performance is a joint product of the content and the function that ranks it. One system rewards watch time, another completion rate, another reply volume — and the same artefact scores differently against each without changing at all.
What is actually happening
Bucher’s study of creators working under algorithmic distribution documents how they infer the ranking criteria from fluctuating reach and then reshape their output around the inferred rule — what she describes as an orientation towards the threat of invisibility rather than towards an audience. Gillespie’s account of the relevance of algorithms supplies the other half: ranking systems encode a specific definition of what is worth surfacing, and that definition is a design decision rather than a neutral measurement of interest. By 2026 the divergence is sharper than when either was written, because platforms optimise for retention windows measured in seconds and publish nothing about the weighting. Identical uploads therefore diverge by an order of magnitude, and the cause is not visible from either result.
Why it stays hidden
The asymmetry hides because creators receive only outcomes, never criteria. Analytics report what happened, not what was rewarded. So the low number gets read as a verdict on quality, and the response — changing the content — addresses the one variable that was already held constant.
Reach is content scored by a ranking function. Change the function and the same file becomes a different object.

The hole in your pen cap is a lung
That small hole in the top of a ballpoint cap is not for airflow to the ink, or for pressure, or for manufacturing. It is there because people chew pens and occasionally swallow the cap.

The reason a platform’s rules change after you build on them
The rules were generous when they needed builders. Once the builders are invested, the rules can be revised, because the cost of leaving exceeds the cost of complying.
AdeptThe hidden part #0287Generous terms attract investment. Investment creates dependency. Dependency permits revision. The sequence is not accidental.

Why network effects make second place worthless
The value of the first network rises with each user. The value of the second rises too, but the gap between them widens rather than closes.
AdeptThe hidden part #0284The first network large enough owns the people. The second can copy every feature except the one that matters.

The reason a habit survives the loss of its reward
The reward that started the habit can vanish entirely, and the habit continues. What was once a means to an end has become the end itself.
