Still plenty (nowhere close to a majority, but more than a few nutters) who are certain the problem is we didn't have a hard enough Brexit. The reason the scientific method is considered an actual discovery is that this whole "In light of new data I realise I was wrong" just isn't how we tend to behave.

For many Leave voters, the fact they voted Leave necessarily means voting Leave was correct - some of them rationalise this as "I was lied to" => "Maybe Leave was the wrong choice but I was misinformed" plenty more reached "Leave was correct but politicians screwed up Leaving somehow, it's not my fault". The current iteration of the Nigel Farage party, named Reform, takes this sort of line.

Once I was writing about the Achilles and the Tortoise story in GEB where the Tortoise rejects Modus Ponens and Achilles discovers, the hard way, that it's useless to argue any point with an interlocutor who rejects this principle. Somebody else on HN pointed out that most people probably would not accept Modus Ponens. And they're probably right, as hopeless as that outcome is.
