It's not a matter of testing it, it's a method of being theoretically possible. How would it work, can it be explained via physics, via psychology etc. Like pyro, moving molecules faster, you got more heat, which can turn air to plasma, so we got fire. Plausable. In other cases, it's a division that has no point nor affinity, so we might consider it just as a thing you can psyhically do,via EM or PK or whatever, and don't make a special category for it.
