When Big Claims Backfire¶
Two days after the most successful LinkedIn post I'd published — 25 likes, 19 comments, six qualified leads — I posted the worst one.
Not the lowest engagement. The most counterproductive.
The post¶
The 330x post led with the productivity multiple. The mathematics: lib-pcb took eleven days; industry standard was nine to twenty-four months; the implied multiplier was 330x at the low end of industry time, higher at the high end.
Correct arithmetic. Terrible communication strategy.
Six likes. Three comments. Zero conversions. Comments that engaged with the claim as an extraordinary statement requiring extraordinary evidence, rather than as a real project with verifiable metrics.
What went wrong¶
The 330x number is defensible — as a mathematical relationship between specific known quantities. But leading with it as a headline claim puts the reader in the wrong frame. Instead of "this person has interesting results to show me," they're in "this person is making an extraordinary claim, let me evaluate whether to believe it."
Evaluation mode is hostile to conversation. It's a debate posture, not an engagement posture. The reader is looking for holes rather than understanding.
The Jan 25 workshop post, two days earlier, said: here's what we're trying to solve, here's the specific work, here's your invitation to participate. The 330x post said: here's a number, believe it.
The first is a conversation starter. The second is a claim to adjudicate.
The lesson in concrete terms¶
There's a version of every productivity claim that's true and verifiable:
- lib-pcb was built in 11 days
- The same scope would typically take 9-24 months
- The resulting library has 197,831 lines, 7,461 tests, 99.8% pass rate
- Manufacturing-ready output
Those specific facts are each individually checkable. They tell the same story the 330x number tells, without triggering the defensive response that round numbers invite.
Conservative specific claims close deals. Large round claims provoke skepticism.
This was the lesson that turned "10-30x typical, 100x+ possible" into the standard framing for all subsequent presentations. Not because it's less true, but because it's more credible — and credibility is what converts.
What to do with a failed post¶
The failure was informative. The three comments that did appear were pointing at the real objection: "you haven't accounted for X, Y, Z in the comparison." Those objections weren't wrong — they were the right questions to anticipate.
The fix wasn't to abandon the productivity story. It was to lead with the concrete evidence and let the audience draw their own conclusions rather than stating the conclusion and asking them to believe it.
"11 days vs 9-24 months" is a fact. "330x productivity" is an interpretation. Facts are easier to believe than interpretations, even when the interpretation follows directly from the facts.
