I said design an intelligence test that a good chunck of humans wouldn't also fail.
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
You think that if we told the average fifth grader in america that they must remember something that is VERY IMPORTANT a week later, and then had them do, say, a book report on a brand new book, and then asked them the very important fact, a 'good chunk' would fail?
Lol yes. People will fail. Any amoumt is enough to show your test is clearly not one of general intelligence unless you believe not all humans fit the bill.
