I notice that non-damaging moves in generation 1 can affect the type that has immunity. For example, tail whip can lower ghost-type's defense. Confuse ray can cause confusion in psychic type. I have been told that thunder wave cannot affect ground type. I haven't tested this, but will anyone please explain this exception?

Thunder Wave is the only status move that accounts for type immunity, in all generations.
