Tell them something important to remember, ask a week later.
Hell plenty normal people would fail your "test"
in our terms, intelligence is (importantly) the ability to (properly) refine a world model: if you get information but said model remains unchanged, then intelligence is faulty.
> humans
There is a difference between the implementation of intelligence and the emulation of humans (which do not always use the faculty, and may use its opposite).
I'm sorry to tell you this but there are many humans that would fail your test. Even otherwise healthy humans could fail your test nevermind Anterograde Amnesia, Dementia etc patients
I'm fairly certain you're incorrect.
