I've come up with a bio-demographic IQ test. All you have to do is make the following calculations, and it should give you a rough estimate of your IQ.
Start by assuming your IQ is -1.251, and then add or subtract based on the following 25 instructions. Be honest or your estimate will not be accurate.
Education
1. If you graduated from elementary school, add 6.212 points
2. If you graduated from high school, add another 6.212 points
3. If you have a university degree, add another 6.212 points.
4. If you have a graduate degree or attended an elite college or high school, add another 6.212 points.
5. If you both attended an elite college AND have a graduate degree, add yet another 6.212 points.
Head Size
6. Multiply your cranial circumference (in inches) by 2.768 and add the resulting number of points.
Height
7. Multiply your height (in inches) by 0.418 and add the resulting number of points
Weight
8. Multiply your weight (in pounds) by 0.0927 and subtract the resulting number of points
Race
9. If you’re less than half-black, add 2.666 points
10. If you’re less than a quarter black and less than a quarter Native American, add another 2.666 points
11. If you’re more than 75% Northeast Asian, or more than 50% Ashkenazi Jewish, add another 2.666 points
12. If you’re more than 75% Ashkenazi Jewish, add yet another 2.666 points

13. Which of the following do you most prefer for entertainment: a) fun TV shows like sitcoms, reality TV, game shows, sports, and popular talk shows, b) intellectual TV shows about science, history or politics, c) fun books like romance novel or thrillers, or d) intellectual books like literary novels or academic texts. If you chose “a” add 0 points, if you chose “b” add 3.451 points, if you chose “c”, add 6.902 points, and if you chose “d”, add 10.353 points.
Sex
