The launch statistic we cannot source
One of our own guides claims that a launch with the maker present converts twice as well as an unattended one. We cannot find a primary source for it. This post explains why we published it, why an unsourced number is worse than no number, and the rule we now apply to every claim.
By the Launchelion team
A guide on this site carries the sentence: a launch with the maker present converts twice as well as an unattended one. It reads well, it matches what experienced makers say, and it is the kind of line that gets quoted. We cannot find a study, a dataset or a primary source behind it.
This post exists because the honest response to that discovery is to say so publicly rather than to quietly edit the sentence and move on.
How a number like that gets published
Not through malice. A plausible figure circulates in launch advice, gets repeated in a dozen posts that cite each other, and by the time it reaches a draft it feels like common knowledge rather than a claim requiring evidence. The multiplier is memorable, which is exactly what makes it spread and exactly what makes it hard to trace.
The underlying advice is still sound. Being present in the comments all day genuinely does change how a launch goes. The problem is the doubling, which asserts a measurement nobody appears to have made.
It is also the shape of claim that is hardest to check and easiest to repeat: no platform publishes conversion data split by maker presence, and no individual maker runs both versions of the same launch, so there is nothing to verify against even in principle.
Why an unsourced number is worse than none
It converts a defensible qualitative claim into an indefensible quantitative one. A reader who checks and finds nothing learns to discount everything else on the page, and a competitor who checks gains a free argument against the site.
There is also a mechanical cost. Answer engines lift extractable statements, so an unsourced statistic is precisely the sentence most likely to be quoted elsewhere with your domain attached. Being cited for a number you cannot defend is not a win.
The rule we now apply
That last rule exists because we have seen exactly that failure in our own research inputs: a star count that was accurate in March 2026 and wrong by mid-year, and a revenue figure repeated across secondary blogs that the closest thing to a primary source contradicted.
- Every statistic appears with its source named in the same sentence, plus the date of that source.
- A claim with no source is cut, not softened. Rewording it as studies suggest is worse, not better.
- Our own numbers are computed from our own rows, with the method and the sample stated.
- Vendor metrics are verified on the day of publication, because star counts, revenue figures and user totals rot within weeks.
What we ask of makers, for the same reason
The listings on this board carry numbers: revenue, launch dates, votes. Revenue connected through a payment provider is labeled verified and everything else is labeled claimed, and it stays that way even when the claimed number is probably true. Applying a weaker standard to our own guides than to submissions would be indefensible, which is the whole reason this post exists.
