@LonM So, I’ve been asking around here in Iceland and the consensus here seems to be that reading comprehension has declined, but not as much as we’re hearing from English-language countries.
Still, I know of a few kids who are about to head to college who’ve complained that they feel incapable of reading what they call “grownup” books. Not because they aren’t interested but because they feel they don’t understand the books when they try.
