True, except something like a geography test would exclude about 75% of Americans under 40 years of age (being over 40, I can say that).
The W3C is
unhappy about the existence of captchas, claiming they discriminate against visually impaired Internet users. One could use an audio captcha, but that discriminates against the aurally impaired. And I'm afraid a logic or geography test discriminates against the intelligence impaired.
How do you broaden the test so you can include these groups of humans, while excluding machines?
