Isn't the difficulty tuned to produce a histogram close to that of a normal distribution? Yes it's true that the contents of the test have changed (removing analogies, and then recently circa 2016 revamping the writing/reading sections to be more like the ACT) but fundamentally it doesn't really look that different to me. In fact if anything now the reading section relies more on understanding and analysis of passages rather than just memorizing words and definitions which if anything seems like slightly raising the bar.
