I'd say Vizlet represents what she wants out of Yinglets as a whole
As is, she's at least as smart as the average 'conventionally intelligent' human, in that she's likely smarter than 50% of all humans. She's by no means a genius, but she's very sharp and more than a little savvy politics-wise.
That said she is definitely an outlier, the average Yinglet is, as stated before, roughly on par with a particularly dull child, with smarter ones, such as the patriarchs, being somewhere around early teen level in terms of self awareness.
What Vizlet no doubt wants is to institutionalize a widespread education program, in which the smart Yinglets and the dumb Yinglets will be more easily sorted out. She no doubt plans to breed smart Yinglets with other smart ones while denying or limiting the breeding rights of the subpar Yinglets. In this capacity Yinglets like Vizlet may rise up and become a ruling class of sorts.
To this end, she needs Kass and his connections to the Invenmoths to acquire the educational resources to implement her nefarious education schemes.
