It's no doubt accurate to say that everyone is subject to the Dunning-Kruger effect (heretofore DK). The problem is, there is an inverse relationship between its effects and awareness of its presence: in other words, the less we know, the more we think we know.
Now, we all like to think we're immune to the effect, but it seems to me that it is built into the nature of things. Literally. For as we've discussed before, it is only possible to know anything about anything because we cannot know everything about a single thing.
In other words, our finite intelligence is, as it were, an echo of God's infinite intelligence. That being the case, one could define God as the one being who necessarily doesn't suffer from DK but makes it inevitable (or in-Eve-ate-apple) for the rest of us. Awareness of this principle makes a man humble. Denial of it makes a man proud. See Genesis 3 for details. Indeed, you could say that DK is merely a form of idolatry (or maybe vice versa).
Is there more DK these days than in the past? The answer may surprise you. But first I have to think about it.
I was about to say there is more of it, but it's much like trying to determine if there is more greed, cowardice, lust, or envy than in the past. All we can say is that these are all permanent features of human nature, so they will always be present to one degree or another. We do, however, agree with Sr. Dávila that
Modern stupidities are more irritating than ancient stupidities because their proselytes try to justify them in the name of reason.
Modern sophisticates like to imagine that people of the past were immersed in a religious worldview that caused them to think they knew much more than they did -- in other words, that religion is just a cover for ignorance. But again, the temptation to idolatry is ineradicable, such that we have any number of ideologies (or better, ideolatries) that serve the same function, e.g., scientism, Marxism, Darwinism, and all the rest.
Science? Please. We love science, but to think that it can provide any kind of comprehensive explanation of the world is the purest DK. No one can can be a great scientist -- or thinker at any rate -- who is only a scientist. Consider:
--To believe that science is enough is the most naïve of superstitions.
--Nothing proves more the limits of science than the scientist’s opinions about any topic that is not strictly related to his profession.
--Stupidity appropriates with diabolical skill what science invents.
--Being only falsifiable, a scientific thesis is never certain but is merely current.
--What is capable of being measured is minor.
Exaggerate much? No, not at all, because Science, when it finishes explaining everything, but being unable to explain the consciousness that creates it, will not have explained anything.
In other words, once you've reduced to the world to a calculation or quantity, you'll still have to account for the calculator and quantifier. And there is -- literally -- an infinite distance between the two. This distance is -- literally -- unbridgeable from the bottom up. Conversely, from the top down it is not only explicable but even necessary, in the sense that it is necessary for the Creator to create.
Which is another way of talking about the complementary principles of immanence and transcendence. Scientism imagines the world can be intelligible without intelligence, which is to say, immanent without transcendence. But if intelligence isn't transcendent, it isn't intelligence, precisely.
Or, put it this way: if there is no transcendence -- no vertical inscape hatch -- then all statements are ultimately tautologies. To take an obvious example, if we are explained by our genes, then we couldn't explain our genes. Rather, the explanation would be genetically caused and therefore circular.
Only recourse to transcendence accounts for both the continuities and discontinuities of the world. Again, from the bottom up -- from any materialistic standpoint -- intelligence and intelligibility, mind and matter, must be discontinuous. And if they are purely discontinuous, then there is no accounting for knowledge. Knowledge could only be an illusion of continuity, just a projection of our own psychic categories. Taken to the extreme, it would mean we can know everything about nothing. Terminal DK.
In truth, there are real continuities and discontinuities built into the nature of things, the former being radial, the latter circumferential. Imagine a circle with a point at the center: ʘ. That's God (or Creator) at the center, world (creation) at the periphery. However, there are multiple worlds, e.g., metaphysics, physics, chemistry, biology, et al. As such, we have to imagine a series of concentric circles, each corresponding to a particular world.
But there is also continuity, which can be conceptualized by imagining an arrow (or arrows) emanating from the center. And guess what: you -- your soul -- is one of those arrows, precisely. This is what it means to be in the image and likeness of the Creator (the center), and why we can have real knowledge of the other circles. Each circle discloses truth, but only because they are linked (via the arrows) to the Center.
DK prevention, right there.
