You know, at first the idea of the Galvans being high intelligence-low wisdom made me wonder if the Cerebrocrustaceans have slightly more wisdom than the Galvans to contrast being slightly less intelligent than them.
Then I remembered that one of their best scientists thought that a reasonable response to First Thinker-senpai not noticing him was to blow his planet up, and realized that nope, they’re just as lacking in the wisdom department.
Now I'm just imagining the Contumelia coming up with alien species to populate the newly-created galaxy with and making two ridiculously smart ones before going “wait, we can’t make them too OP, we have to nerf them somehow”, and in addition to having one species be five inches tall and giving the other species no hands, deciding to make them complete dumbasses when it came to practicality and sound judgment.
Galvans are considered smarter on the long term, being typically more intelligent than cerebrocrustaceans on the technicality that they plan thinks beyond one certain goal; there's a longevity to galvan tech that cerebrocrustacean tech has not been designed around, which is not quite 'planned obsolescence' persay but 'right to break' style fixing and updating versus 'goal a, b and c' design philosophy.
But that tends to make galvans 'slower' to think because they (as a generalised statistic) like to plan things to a more completed state, whereas cerebrocrustaceans are great at coming up with disposable instant ideas and solutions and move on to the next to outthink the situation they're in. In other words... autism vs ADHD /lh /hj adlkfhgfkl-!
I think the reason why species known for their wisdom aren't heard about in the wider galactic sphere (beyond just not having a concept in the world of Ben 10) is because they have a high enough wisdom to not get involved too heavily beyond their own scope. I mean certainly they'd be wise enough to retort were anything to happen to drag them out but, unless you're a 'wise guy' sarcastic trickster individual or 'look at what i can make' big brain smart alec, wisdom might not get you heavily well known (unless you're a geochelone aerio against a power hungry Aggregor)-
Nnnn the contumelia... considering that the construction of the universe is beyond our feeble human understanding, being the looks something up fifth-dimensional beings that they are (depending on what Ben 10 defines as dimension, this could mean they are beings of split timelines and come in the visual form that they do because of the very limited 3D snapshot a three dimensional being imagines which at the very least manifests in matters of emotional sway) they may create and destroy universes for perhaps the intrigue of divergent timelines, but I do not think they have control over the actual species that make that universe home. Something something I don't want to discredit achievements (even fictional ones) to the work of one specific cause, yada yada the contumelia being5D beings that are perhaps entertained by the comparably one dimensional 3D lives merely through the creation of new variable timelines.
