Does anyone know of a pre-existing database of IQ questions & answers? I'd like to develop a web application that incorporates IQ tests, and I'd rather not scrape or invent tests if it can be avoided.

I'm open to suggestions that include licensing costs.

Thank you!

The usefulness of IQ tests depends on the prerequisite that the probands don't know the questions in advance (and did not train for the test). Therefore, all serious IQ tests are not publicly available and are sold only to qualified persons (usually psychologists with a degree). What you are trying to create would invalidate IQ tests. But I guess that's what you are after: helping people who'll pay you score higher. Isn't it? ;-) –  what Apr 20 '14 at 19:15
@what That's not what I'm after at all. I'm trying to create a filtering mechanism for stupid people. –  Calvin Froedge Apr 22 '14 at 4:30
