I've been thinking about reworking IQ-based advantages like Common Sense and Intuition to a "frequency of appearance"-based model, like that used for Allies and Patron. Instead of rolling against IQ you roll against a target number, and modify the cost of the advantage accordingly.

Following the model for Allies and Patron, this would mean

Common Sense (6) costs 10x1/2=5 points
Common Sense (9) costs 10x1=10 points
Common Sense (12) costs 10x2=20 points
Common Sense (15) costs 10x3=30 points

Maybe some other progression - 1/2, 1, 3/2, 2 would be better. In any case, automatic success is not available; nor is Cosmic: No Die Roll Required.
