Sometimes teachers field stories like this to foster critical thought and encourage insightful book reports. It’s stimulating material even with a flawed premise, and that’s the point.
My teachers always seemed to be the type that had these stories in the curriculum, but weren’t the type to follow up with the thinky-thinky bits. This had rather predictable results.
I was in the “gifted/advanced” track too. Teachers saw this one of two ways. Half of them got the memo: you got extra interesting stuff to noodle through because we’re all under-stimulated in a typical class. The others decided to just double your homework load and call it a day. At least the teachers in the first group had some interesting takes on brain teasers and reading material.
And on that note: I must have thought about Flowers for Algernon every week since I read it. Since the 90’s. I’m tired, boss.
