Math ability is one of the best proxies for IQ so I decided to create a little math test for anyone who’s interested. It’s completely anonymous. There are only 10 questions ranging from extremely easy to extremely difficult. The easiest question can probably be answered by over 99% of the general U.S. adult population while the hardest can probably be answered by less than 0.1%. To enhance the g loading, I picked questions that emphasized mathematical intuition and conceptual understanding as opposed to brute number crunching.
There’s no time limit, but try to take the test in one sitting without use of calculator, pen, paper or other aids, though I doubt they would help much. Take the anonymous poll to let us know how you scored.
