Been distracted lately. Adjusted Intelligence value, and added Cunning.

Intelligence:
=============
* Basic cost increased from 25 to 50.
* Threshold lowered from 20 to 10.
* Positive threshold cost lowered from 100 to 75.
* Negative Threshold cost increased from 10 to 40.

This means "the cheap bonus" is +10 for 500 points, instead of +20 for 500 points.
+20 costs 1250 points, and +50 would cost 3500.
Playing a "dumb" race is now more viable - a 90% race gets 500 points, while a 50% race gets 2100.

Cunning:
========
* Threshold lowered from 20 to 10.
* Positive threshold cost lowered from 100 to 40.
* Negative Threshold cost increased from 10

This means less can be gained by lowering cunning, and raising it is more expensive between 110% and 122%, but less expensive for a heavy spymaster race over 122%. Maximum 150% Cunning costs 1850 points. Minimum 50% gains 650 points.
Part of the reason for the overall reduction is that defensive intelligence projects have multipliers to their effectiveness, so even a 50% Cunning empire can build up fairly effective defenses against a single antagonist without a lot of effort. The other reason is that concentrating in intelligence seemed very expensive for the amount of advantage gained. 150% Cunning in the unmodded game costs 3500 points, which is way more than it was worth compared to other advantages.
