Now I'm just being silly:

I have a feeling that a Syker managing to use another Maian would burst every blood vessel in their body, or their skin would automatically flay itself and they'd become a human circulatory system exhibit. It's just so naturally wrong in this world.

Probably like how if a human in the real world tried to use The Force, they'd probably burst a blood vessel in their head before they actually manage to do anything.
