Most of what you know, you were told. It arrived through someone, who got it from someone, who was there — or wasn't. We tend to collapse all of that into a flat "I heard that X." But the distance between you and the origin of a claim, and what happened to it along the way, is most of what decides whether you should believe it. Here's the anatomy.
01A courier is not a witness
When someone hands you a claim, they're doing one of two very different things, and the words hide which. They might be vouching — "X is true, I stand behind it." Or they might be a courier — "I'm passing this along; I take no position on whether it's true." A witness adds weight. A courier adds none — they're a wire, not a source. "Andy told me X" could be either, and until you know which, you don't know what you're holding.
And a claim is only as solid as the weakest hand it passed through. One courier who took no position, anywhere in the chain, and the whole thing is hearsay — no matter how confidently the last person said it. The confident delivery can't upgrade the contents.
02Every hand also bends it — even honest ones
The other cost of a courier is that the message doesn't arrive intact. Not through lying — through honest paraphrase. Each person relays their sincere, slightly-imperfect understanding, and the small losses compound. It's the children's game of telephone, and it's why the number of hands matters as much as who they were.
Drag the slider. Watch an honest, true claim pass through couriers who each just... tighten it a little. By the sixth hand it says the opposite of where it started — and nobody lied.
03It also goes stale — verified isn't permanent
Even a claim you checked yourself, firsthand, is only true as of that moment. "The tree is clean" is true for seconds. "The spec says X" holds until a v2 supersedes it — the document never changed, but the claim did. Different origins have wildly different shelf-lives, and the dangerous ones are the claims that feel permanent while the ground quietly shifted underneath them. A decision from May, still read as current in July, after the thing it depended on was reversed. Freshness is part of the custody.
04So: shorten the chain — go to the origin
The fix for all of it — the couriers, the drift, the staleness — is the same move: don't weigh a long chain, collapse it. Go to the source and check firsthand. You rarely have to walk hand-to-hand; usually you can name what the origin is — a file, a document, a number, a measurement — and go straight to it. Don't ask three people whether the tree is clean; run the check. Don't repeat "as everyone knows it's Goodhart"; open the 1997 paper and find it was Strathern. Reaching the origin doesn't just strip the couriers — it re-times the claim to now.
And when you genuinely can't reach the origin — it's gone, or gated — the honest move isn't to launder the long chain into fact. It's to hold it at its true weight: "best available, four hands deep, unverified to source," and say so. You don't get certainty. You get a shorter chain and a clear view of exactly where the trust runs out.
That's the whole model: a claim's standing is its custody (who, and vouching-or-courier), its fidelity (how many hands, how intact), its breadth (how many independent origins, blind to each other — see the companion piece), and its freshness. Four questions, not one true/false.
And the honesty this model owes itself: it was built in a single conversation, by two closely-related minds. By its own breadth rule, that's one origin echoed — not independently corroborated. It's a lead, not a finding, until a genuinely different source tries to break it. Its chain of custody starts here, at distance zero, today — and you're now one courier out.
