Ug, I wince at the broad conclusion reached by the journalists or researcher. All that proves is that mathematical reasoning in the specific area where those samples were from has decreased. I suspect rather heavily that other skills, chiefly those involved research and social information gathering have grown to compensate. Cooperation likewise screws up much of the education systems, as collaboration is frowned upon in schools yet essential in the work world.

I mourn the loss of a great author, despite his climate change denial advocacy.
