Heh, that's higher than I expected, based on personal experience...
But yes, I have complained about this subject (the dumb questions I mean) several times, it's not just here but everywhere.
And while it's always been a thing, it has gotten exponentially worse over the last 5-10 years, and I think diminishing social skills also plays a small part in it, not just the lack of thinking.
Hell, 22 years ago when I was in AP calculus in high school, I was floored at how dumb everyone was. Like, this was supposed to be advanced track math and it took 2 weeks to go over the first night's homework, which was just a review of algebra and the most basic parts of trig. Like how did they even get in the class?
And so often teachers have to teach to the test rather than teach understanding. Like, as an example, kids today just memorize and are taught area of a triangle is 1/2 • base • height but not why that is (because area of a rectangle is base • height and any triangle can be duplicated and rotated on itself to be a rectangle or parallelogram, so if all triangles are half of a rectangle, then their area formula is half that of the formula for a rectangle).
They're no longer forced to think, they're just given answers or given a formula, and they have no ability to extrapolate, and lock up when things aren't exactly/explicitly "by the book". They don't understand the real world is messy and you need wiggle room.
It's a lot of confluent factors involved.
