But Wisdom is the relevant ability when it comes perceiving what other people feel or want (Sense Motive), or just understanding other people in general...and that's a field Janine has trouble with.
And mental problems are often presented as a Wisdom penalty. Derros, who are mad, have a Wisdom penalty that gets fixed when they are cured of their racial madness.
I guess Janine, written as a character, would just have high Wisdom combined with a ton of Flaws: a huge penalty to Sense Motive and Diplomacy, to start with, and probably she would have to make Will Saves to avoid saying something inconvenient/awkward when meeting an attractive man, and to avoid being shaken when rejected...
