The Earth Alliance government’s response to the appearance of human telepaths in
Babylon 5 would sadly probably be the most likely to happen if psychic powers ever became a reality.
- All humans displaying telepathic abilities are required to register with the government and become members of the Psy Corps, effectively segregating out telepaths from the population and putting a collar of control on their abilities. However, this also creates a monstrous organization full of jackbooted people in black uniforms who have been taught little to no connection with the rest of humanity, making it far easier to build resentment and foster feelings of superiority.
- Those who refuse to register with the government have 3 options: 1) agree to be jailed for the rest of their lives, 2) regular drug suppressants that have the side effects of depression and increased chance of suicide, or 3) go on the run.
Within
Star Trek, the nature of the Federation makes it harder to see laws targeting the abilities of certain species, since that would seem kinda discriminatory and go against the entire idea of building a diverse interstellar government. If I was a Betazoid, why would I join a Federation that would lay down rules about my abilities because they don’t trust me as who I am?
On the other hand, although it’s not canon, I seem to remember something, either in the novelization or some other non-canon material, about Lt. Ilia from
The Motion Picture having to take drugs/vaccine in order to deactivate the mind bending pheromones she has as a Deltan before serving in Starfleet. And I would guess something like that might be true for Tendi and the other Orion women that serve in Starfleet too.
