Nero, you are an example to all the children on this shuttle. Because most of them are so foolish, they think it is better to keep their stupidest thoughts to themselves. You, however, understand the profound truth that you must reveal your stupidity openly. To hold your stupidity inside you is to embrace it, to cling to it, to protect it. But when you expose your stupidity, you give yourself the chance to have it caught, corrected, and replaced with wisdom. Be brave, all of you, like Nero Boulanger, and when you have a thought of such surpassing ignorance that you think it's actually smart, make sure to make some noise, to let your mental limitations squeak out some whimpering fart of a thought, so that you have a chance to learn.

...you seemed to be listening to me, not to find out useful information, but to try to catch me in a logical fallacy. This tells us all that you are used to being smarter than your teachers, and that you listen to them in order to catch them making mistakes and prove how smart you are to the other students. This is such a pointless, stupid way of listening to teachers that it is clear you are going to waste months of our time before you finally catch on that the only transaction that matters is a transfer of useful information from adults who possess it to children who do not, and that catching mistakes is a criminal misuse of time.

I'm not stupid!" In Bean's experience, that was a sentence never uttered except to prove its own inaccuracy.

And then he thought: Is this how idiots rationalize their stupidity to themselves?

That's what Ender has to understand. There really is evil in the world, and wickedness, and every brand of stupidity. There's meanness and heartlessness and... I don't even know which of them is me." - Hyrum Graff

Hive Queen: They never know anything. They don't have enough years in their little lives to come to an understanding of anything at all. And yet they think they understand. From earliest childhood, they delude themselves into thinking they comprehend the world, while all that's really going on is that they've got some primitive assumptions and prejudices. As they get older they learn a more elevated vocabulary in which to express their mindless pseudo- knowledge and bully other people into accepting their prejudices as if they were truth, but it all amounts to the same thing. Individually, human beings are all dolts.

Pequenino: While collectively...

Hive Queen: Collectively, they're a collection of dolts. But in all their scurrying around and pretending to be wise, throwing out idiotic half-understood theories about this and that, one or two of them will come up with some idea that is just a little bit closer to the truth than what was already known. And in a sort of fumbling trial and error, about half the time the truth actually rises to the top and becomes accepted by people who still don't understand it, who simply adopt it as a new prejudice to be trusted blindly until the next dolt accidentally comes up with an improvement.>

Pequenino: So you're saying that no one is ever individually intelligent, and groups are even stupider than individuals-- and yet by keeping so many fools engaged in pretending to be intelligent, they still come up with some of the same results that an intelligent species would come up with.

Hive Queen: Exactly.
