I make mixups like that all the time or use loose language to convey a general point that's rather narrow and approximate and even shortsighted rather than precise, and I see nothing inherently wrong with doing that whatsoever. That's what discussions and critical thinking are for! I like when people have a back and forth with me, and offer different ways of conceptualizing things, and it's totally fine if they're not pedantically precise about everything.

It can sometimes be helpful to be super precise, and that's something I'm good at, but you don't ever have to feel bad about saying something that happened to be wrong or that was right but imprecise. If I correct you or offer an alternative viewpoint, I'm really just building on the wisdom that you bring. If you hadn't said it, I wouldn't have been able to engage with it, and I do so love engaging in discussions, which is why I do it.

Education is a good point too! If we substitute that for IQ I bet you're right and the same tendency holds true.
