Sorry, I meant the effect maxes. I think sage increases the max effects, with the same number of scientists required to reach the max. But I can't confirm this 100% yet but several threads in strategy said or implied this. You may want to check the other personality / race science effects too.
This is what your plug in is showing as sage:
Science Type Scientists Max Effect
Alchemy 15 15 +21.0% Income (30% max)
Tools 8 20 +4.2% Building Effectiveness (20% max)
Housing 11 25 +4.2% Population Limits (15% max)
Food 2 20 +14.0% Food Production (200% max)
Military 3 25 +1.3% Military Efficiency (15% max)
Crime 2 20 +7.0% Thievery Effectiveness (100% max)
Channeling 2 21 +8.4% Magic Effectiveness & Wizard Production (125% max)
