True, But Incomplete
Half-Truths Are The Whole Trick
TL;DR: There’s a word for using true facts to create false impressions. It’s not lying – it’s worse. And you’ve probably already fallen for it this week.
Someone at a dinner party told me CO2 is making the earth greener. I did what any annoying person would do. I checked.
They were right.
A 2016 study in Nature Climate Change found that rising CO2 explains roughly 70% of observed greening across the planet. NASA confirmed it. Satellite images confirmed it. Peer-reviewed, replicated, real.
I almost stopped there. That’s the dangerous part.
Because “CO2 is greening the earth” says nothing about ocean acidification, extreme weather, sea levels, or that the greening itself is already slowing. One data point, surgically removed from everything around it, walks into the room wearing the full authority of science. You check the data. It checks out. So you extend credit to the conclusion, and the conclusion was never in the data to begin with.
Turns out there’s a word for this: Paltering.
The active use of truthful statements to create a false impression. Harvard Business School calls it: “How To Deceive Others With Truthful Statements”.
Not lying, where you say something false. Not omission, where you stay quiet. Paltering is active. You reach for a true fact, cite it correctly, and arrange it so the listener walks away with a conclusion the fact alone doesn’t support.
A lie can be caught. You can point at it, label it, fact-check it. Paltering hides behind the facts. You can’t call it false.
You can only ask: what didn’t you tell me? And that question is much harder to ask when the first thing you were told was verifiable.
Call it the first-fact free pass.
Once you verify the opening claim, you extend trust to the conclusion.
Verification is expensive – so we verify the number, not the inference. We check whether the data is real, not whether it’s sufficient. A lie requires you to fabricate something that survives scrutiny. Paltering just requires one fact that does. The rest rides free.
The Trillion-Dollar Silence
Every number DOGE (Department of Government Efficiency) published is, in a narrow sense, accurate. Contracts were cancelled. Ledger entries were removed. Add up the sums and you get something around a trillion dollars.
Now watch what didn’t get said.
Many of those contracts still need to happen. Some were cancelled on paper and quietly recontracted through different channels. Some grants, counted at full ten-year value, were cancelled before a single dollar was disbursed. Saving money by cancelling a gym membership you never used.
The promised dividends never materialized.
The savings were announced. The benefits weren’t. (Classic Musk)
The methodology is the trick, and methodology doesn’t fit in a press release. By the time you understand why “cancelled contracts” doesn’t equal “money saved,” the headline has done three news cycles and moved on.
“Renewables are cheaper than fossil fuels” runs the same play: the Levelized cost of electricity (LCOE) numbers are real, and they quietly assume someone else pays for storage, intermittency, and grid buildout.
Germany learned this the expensive way – Energiewende hit every cost target and still raised household electricity prices to among the highest in Europe. Same mechanism, different jersey.
Your Feed, Their Frame
A geologist posts the same CO2 greening study on X with the caption: “We will look back at the demonization of CO2 with shame.”
120,000 views. 4,000 retweets. The thread explaining why it’s incomplete gets two hundred.
The algorithm didn’t palter. It just learned what keeps you scrolling.
(It says so in the privacy policy – which is itself optimized for nobody reading it.)
The palterer and the platform feed each other. Neither planned it. Both benefit.
The thing is, nuance has a distribution problem – and by the time you notice, you’re two conclusions downstream from where the trick happened.
My imperfect heuristic: when a fact arrives pre-shaped into a conclusion, I ask what else would have to be true for it to actually hold.
I keep coming back to that dinner party… not because I was lied to, but because I was being curated into a worldview, one verified fact at a time.
The person who told me about CO2 greening wasn’t malicious. They’d read a real study and shared a real finding. The paltering wasn’t theirs. It was upstream, baked into whatever article stripped the context before it reached them.
They were doing the palterer’s work for free.
Most of us are.
