The Pokemon literally called Psyduck isn’t a Psychic type. What?????

In fairness, its Japanese name (Kodakku – probably ko, child + duck) doesn’t have any reference to psychic ability, and nor does Golduck’s name, in any language.  I’d suggest that the reason Psyduck isn’t a Psychic-type is because of his infamous lack of control over his psychic abilities, which only manifest when his headaches send him into a trance that he can’t remember once it’s over – true Psychic Pokémon have much greater focus.  Then again, I’ve actually argued in the past that this was originally supposed to be a character trait of Misty’s Psyduck specifically, not Psyduck in general.  The first Pokédex entry from Red and Blue says of Psyduck: “while lulling its enemies with its vacant look, this wily Pokémon will use psychokinetic powers,” which is a very different perspective than just about every later portrayal.  It’s only in Yellow version, which is based on the anime, that we get “always tormented by headaches. It uses psychic powers, but it is not known if it intends to do so.”  So what I’m saying now is actually contradicted by other things I’ve thought about Psyduck in the past; I’m probably wrong about one of these things, but I’m not sure which I like better.
