The wise connoisseur of argumentation will quickly learn to recognize these tactics and appropriately discount everything the speaker says, noting that they care not for what is true but for what they can make you believe is true. As such, you can't really accept any claims they make: you have to verify for yourself. (You can, of course, verify the valid application of any logic yourself.)

It doesn't mean that the speaker is wrong in their conclusion, only that you will get little to no help from them in determining whether they are right or wrong and to what extent.

And an enlightened society will not lean into these tendencies but teach people how to recognize and appropriately discount them.

It's too common these days to note the problem and go, "Oh, well, I guess humans are just hopelessly irrational--let's get with the program and BS everything." Except that itself is BS: there are many examples of many people being able to reason effectively even in the face of concerted well-crafted BS. (Check out an election in California, for instance. While Californians are by no means perfect, their record in not being taken by BS about various propositions is reasonably good; BS isn't a magical "automatic win" card, when well-done it can shift things by a few points and that's about it.)
