The dual-action system of scientist + books is probably causing alot of problem. Might be difficult to control, as is obviously shown. Reverting to just 1 direct parameter to increase/decrease, instead of two with labs and schools etc, would probably make it alot easier.

It may "force" everyone to pump scientists for 2-3 weeks at start of age, to be able to be competetive in the end... seems a bit boring with lots of denied wars back and forth.
