Yes, you've made a good point. But the way I understand the Kruger effect, is something slightly different. My earlier definition was simplified.
The effect is really about when someone has low/not enough knowledge about a topic, but because they get some information—especially if they hear the same message repeated a few times—they start to think they know enough to be an "expert." They begin to trust that information so much that they feel ready to educate others, they feel very firm about their opinion. Here’s an example: Someone hears in the media that vaccines are safe and effective. They decide to "double-check" and see two more sources saying the same thing, and only one saying otherwise. Since they don’t want to dig deeper into why that one source disagrees, they just go with the majority view. They now believe vaccines are safe and effective, and they'll repeat that to others—even though their own knowledge is still pretty thin. And the more someone challenges their view, the more defensive they get and the stronger their belief becomes. That’s how misplaced confidence builds. Overall, it’s a kind of bias—a mental trap that can happen to all of us, where we take in some information, attach it to whatever narratives suits us, and then treat it like the only truth, without ever really checking for gaps or flaws. I'm not saying the effect is 100% correct and occurs always everytime to everyone but in many cases it's correct just proving that human brain often triggered by ego, mental laziness or whatever the cause, is very prone to makes us believe in too many things that are not verified. Simply, makes us trust the given status quo.
