I'm a 12-year-old from an Atheist Asian country and I don't even know bible stuff so I looked it up ;-; Luckily I learned some neutron stuff at school recently so I survived that question- The test could have been more specific though but it's basically free so- :)))

So I did the quiz, then looked at my results and the answers I got wrong. I had answered several things completely different from what it said. I think I should have gotten a higher IQ.

Prior knowledge definitely does play a part in IQ test. Take the Weschler Adult Intelligence Scale (WAIS) for example, where Verbal comprehension (i.e., VCI) is measured by a subtest that assesses fund of knowledge (i.e., general intelligence). If I can recall, this assesses crystalised intelligence, which is how well people store and retrieve general information in their long-term memory. However, using cultural specific items, such as the question about the bible, is highly biased to certain cultures and should not be used.

Sorry for my rant haha,
