We have always taken it for granted that there are certain groups for whom lying is natural and habitual. No sane person has ever expected politicians, lawyers or journalists to tell the truth.
Today we have a situation in which many groups that we used to regard as being relatively trustworthy are now also habitual liars. Scientists, school teachers, historians, clergymen, even doctors are now quite likely to lie to us. Not all the time of course, but often enough to represent an enormous sea change in western society. If half the scientists lie to us half the time then that means that we have to assume that scientists are people who cannot be trusted.
There is of course a difference between outright conscious lying and merely repeating falsehoods. In some cases the people repeating falsehoods actually believe their own lies. Sometimes they know that what they’re saying is untrue but they’re too scared not to go along with the lies. I don’t think that many doctors deliberately lie but I am sure that they’re aware that there are certain things that it’s better for them not to question - it’s best to stick to the party line so you don’t get into trouble. I think that very few clergymen deliberately lie - I really think most of them believe it when they tell us that diversity is good for us and that homosexuality is A-OK. In the case of historians and other academics I think it’s a mixture - some believe their own nonsense and some are lying trough their teeth to protect their nice comfy positions in academia.
It doesn’t make much difference in practice. It still means that we now live in a world in which the safe assumption is that we’re probably being lied to most of the time.
We don’t just have fake news. We have fake science. We have fake medicine. We have fake religion. We have fake history. If everything is fake where do we find truth? Does it even exist? Or do we just settle for truthiness?
This is of course an ideal situation for the elites. It doesn’t matter too much to them if we don’t really believe the Narrative that they push. If lies are everywhere and truth cannot be distinguished from lies then we have little choice but to believe the Narrative. Or maybe not believe, but accept it even while knowing that that it is false. Anyone who has read his Orwell knows that from the point of view of the elites being able to force us to believe something that we know is a lie is even better than having us actually believe. It demoralises us even further.
