This test was done for people being examined for military service. It looks like Norway doesn't force military service, but does force people to be examined. Perhaps people just take a mandatory military exam less seriously than they did during the cold war. Also the culture of Norway is much less homogeneous than it was in the 70s and it's impossible to completely remove cultural biases from IQ tests--not to mention far more people who don't speak the language natively.
