Surely, if I sent you to them, they would listen to you. But the house of Israel will not listen to you, for they are not willing to listen to me; because all the house of Israel have a hard forehead and a stubborn heart. See, I have made your face hard against their faces, and your forehead hard against their foreheads. Like the hardest stone, harder than flint, I have made your forehead; do not fear them or be dismayed at their looks, for they are a rebellious house (Ezekiel 2:6b-9).
It’s called the Dunning-Kruger Effect—”a cognitive bias in which people wrongly overestimate their knowledge or ability in a specific area. This tends to occur because a lack of self-awareness prevents them from accurately assessing their own skills (Psychology Today). To some extent we all suffer from DKE, as I will call it. We can believe we know what’s best for ourselves and are smarter than we think.
