What determines if a soldier is gifted with psionic powers?
After just building the psionic training facility, I immediately test all my soldiers for having the gift.
Among my original collection of soldiers, two soldiers had the gift, the rest had not. I immediately started ordering new rookies, testing them all for psionic abilities. But after hiring 20+ soldiers, none of them had the gift.
Is this normal that it is so rare for the soldiers to have the gift? Or can there be a problem that no psionic abilities are found when testing soldiers with no combat experience?
I am playing the PS3 version (but I doubt that it should matter)
