It looks like we will have tax free books in Denmark soon (Hurray!), partly to try an encourage more reading (though our libraries are booming) after #PISA2022 showed alarming decline in reading ability. This was IIRC the case across the OECD, I haven't seen a very convincing explanation for the decline in maths, science and reading performance (which started way before COVID shutdowns).
Has anyone done any research to understand why?
