>>54897253It's one of those relationships that isn't strongly defined by popular culture, so the game devs are totally free to just dictate how the interaction works in their world.
You couldn't have ever reasonably made it so that Grass wasn't weak to Fire for example, pop culture and basic logic demands it be that way. But how do a phantom and PSI-user interact? There's no precedent/conflicting pop culture interpretations so it's free game. Sure, NOW we're all used to Psychic being weak to Ghost but if we had grown up with Ghost being weak to Psychic we would all perceive it as normal. Just say ghosts are immaterial beings so psychics are among the only ones who can hit them dead-on in the immaterial plain. Y'know whatever. It can go either way
