The orphan statistic
A precise percentage, with no source, no scope, no date. The number does not support the demonstration: it stands in for it.
If nobody can say where the number comes from, the number proves nothing: it decorates.
What holds, and what does not
The technique itself is neutral. What changes is the gap between what the line promises and what the post delivers.
Cite the source with the number: author, year, sample, or link to it in the comments.
State the scope in the same sentence as the percentage.
If you cannot trace a number's origin, write instead what you observe at your own scale.
Do not open a post with a percentage you would be unable to source.
Do not write "according to a study" without naming the study.
Do not repeat a number because it circulates: its frequency in the feed is not a source.
Three markers
The number is precise, the source absent
87%, not "most": the precision imitates measurement. But no author, no date, no sample accompanies the percentage.
The scope is missing
Percentage of whom, where, when, measured how: the sentence does not say, and neither does the rest of the post.
It opens the post
The percentage sits in the first line, before any reasoning. Placed there, it concludes nothing: it hooks.
The same mechanism, three forms
« 92% of career changes fail within the first year. »
The number alarms and sets up the problem the post will solve. No study, no country, no definition of what "fail" means.
« According to a recent study, 78% of employees are thinking about quitting. »
"A recent study" imitates citation without allowing verification: no author, no date, no sample. The phrase serves as the source.
« 8 out of 10 recruiters reject a resume in under 6 seconds. »
The precision of the "6 seconds" gives the number the appearance of a measurement. Its circulation from post to post serves as its source.
The mechanism
In the feed, a number stops the eye before the words: it is the most visible element of a text and the fastest read. Placed at the opening, it sets up the problem the post promises to solve, with the authority of a measurement and the economy of a demonstration.
Precision imitates method: "87%" seems to come from a study where "most" would be a mere opinion. The reader has neither the time nor the means to verify while scrolling; they grant the number the credit of a statistic without demanding its source.
The orphan statistic circulates better than the sourced one: without a scope, it applies to everything and gets copied without citation. Many numbers in the feed now point only to other posts repeating them; circulation has replaced measurement.
Four questions
A percentage with no source and no scope.
An honest statistic comes with its author, its date and its sample. "A study shows that" is not a source, it is a phrase.
87% of whom: French recruiters, users of one tool, respondents to an online questionnaire? Without a scope, the percentage has no object.
Follow the number through the post. If it is never revisited or used after the first line, it was serving as a hook.
Look for it outside LinkedIn. Many of the feed's statistics point only to other posts quoting them, never to the study that supposedly produced them.
The neighbors
The pattern-break hook
The orphan percentage often supplies the bare number of the first line.
The cropped screenshot
Visual proof without verifiable context, cousin of the percentage without a source.
The round number
The same number-as-proof: here the source is missing, there the result is too neat to have been measured.
Say where the figure comes from, in the same sentence.
