>>48820387There's no lore ever stating psychic Pokémon are more intelligent than others. Second that doesn't matter at all because all Pokémon display similar levels of intelligence, even more so in the anime like an octillery that was a chef. Similarly you can look at other media like Yogi Bear talking, speaking, wearing a tie and hat and having human level intelligence but at the end of it all he's still a bear that is looked after the park ranger.
It doesn't really matter how intelligent it really is because Pokémon doesn't take that into account. It's still not a person in universe, it's fed dog food, kept in pastures, ranches and zoos, lives like a wild *magical* animal and the games have you play fetch with it like it's your pet dog. Pokémon has never said this Pokémon is more human or alien than the others, it presents Pokémon as being one big group who are grounded in what an animal is in the real world with fantastical qualities. Gardevoir is a fantasy animal just like Cinderace or eevee albeit with a more fantastical design like Indeedee and Victini. It is not an alien who can't be compared to a twi'lek especially one of those very human aliens.
