Except it's the opposite - empirical evidence is very easy to ignore. Between herding, the replication crisis, and the overall insularity of academia, trust in "studies" has never been lower.
But people still respond very well to demonstrative or pragmatic evidence. Empirically there's nothing special about a keto diet. But demonstratively the effects are very convincing.
That didn't happen. And if it did, it wasn't that bad. And if it was, that's not a big deal. And if it is, that's not my fault. And if it was, I didn't mean it. And if I did, you deserved it.
At the top level (of government and corporate entities) those people always knew it was real, the messaging just changed as it became harder to keep a straight face while parroting the previous message in the face of overwhelming empirical evidence.
Exxon's (internal) research in the 1970s has been very accurate to the observed reality since then.
They just didn't care that it was real because they valued profits/power/etc in the moment over some difficult to quantify (but certainly not good) future calamity.
You would think they would care at least in the cases where they had children and grandchildren who will someday have to really reckon with the outcome, but you'd be wrong, they (still) don't give a shit.
