There has to be a name for this state of being

Adult ADHD.

*Undiagnosed & untreated ADHD

Undiagnosed.

Being smart is largely about being able to process information, not retain it. Retaining it is being educated.

Also a bit of knowing about a lot of topics but not well enough to explain any of them
Not entirely. In case of ADHD, the memory is highly choosy in what to retain. Which has genetical causes.
- Right. My husband is intelligent, able to process information well. However, he also has ADHD and can't remember things for shit. He's also not highly educated, though, so not the best example. Still, you can be intelligent without being able to retain information is the overall point.
- And thus, those with ADHD are uneducated. Next!

Clever.

They're trying to make a joke, but that's the word for someone who is capable in unknown situations.

That's a clever answer!

...or maybe a smart answer. Depends if you've seen the question before.

I think in elementary school they refer to that as “bright.”

“Oh little Billy is one of the brightest students.”

Fast forward, little Billy graduated college, moved to Philly, works as a barista, knows the complete lore of 40k but doesn’t use their degree in any meaningful way.

Intelligence 20 Wisdom 0

Shouldn't it be the opposite? High WIS but low INT?
- Intelligence represents how clever you are and what you know, basically how quick your mind is at improvising solutions.
  
  Wisdom is your awareness of your surroundings as well as how much of that you retain and can access on demand without further stimulation.
  
  Int 18 Wis 8 would be like a professor of advances sciences or engineering (doesn't matter what field) who can give indepth breakdowns of things in their field work and expected outcomes of things related to that field. But that same professor can never remember where they put their glasses, lab notes, the homework or remember anyone's name without serious attempts to grill it into their long term memory.
- I dont think so. Intelligence is aptitude, capability, or skill. Wisdom is knowledge and experience, etc. So op is right, i believe

Impostor syndrome.

The closest concept is severly deficient autobiographical memory (SDAM), a lifelong inability to vividly recollect or re-experience personal past events from a first-person perspective.

You can just call it ADHD my man.
...this is another aphantasia thing, people can recall memories in first person!?
although there's also stupidity
