Anyone who answers at least 50% correctly will be listed as a recipient of the prestigious Pumpkin Person degree in heritability, and anyone who scores in the top 10% of test takers will be listed as a magna cum laude graduate. You may not discuss questions or answers in the comment section.

TEST QUESTIONS ………………………………………

ALL QUESTIONS ASSUME THE PHENOTYPE = GENOTYPE + ENVIRONMENT MODEL; ALL ANSWERS ASSUME BROAD HERITABILITY

1) If the correlation between identical twins separated from conception into random American environments is 0.8, what is the heritability of IQ in America?

2) If everyone had the exact same environment, what would be the heritability of IQ?

3) If everyone had the exact same genes, what would be the heritability of IQ?

4) If IQ has a heritability of 0.8 in America, what is the correlation between IQ and genetic IQ among Americans who as embryos, were implanted into random wombs and were adopted into random homes?

5) If g has a heritability of 0.8, and only the g component of IQ was heritable, what would be the heritability of an IQ test with a g loading of only 0.6?

6) If the IQ of the same individuals tested twice correlate 0.9, and the IQ correlation of identical twins raised together is 0.8, what percentage of IQ variation is explained by unshared environment, uncorrected for reliability?

7) If the IQ of the same individuals tested twice correlate 0.9, and the IQ correlation of identical twins raised together is 0.8, what percentage of IQ variation is explained by unshared environment, corrected for reliability?

8) If the IQ correlation between criminal fathers and their criminal children is 0.5, and the average criminal has an IQ of 90, what would be the average IQ of criminal children who have criminal fathers with an IQ of 150?

9) If the IQ correlation between criminal fathers and their criminal children is 0.5, and the average criminal has an IQ of 90, what would be the average IQ of criminal fathers who have criminal children with an IQ of 150?

10) If the IQ correlation between MZ twins raised together in America is 0.9 and the correlation between DZ twins raised together in America is 0.5, what is the heritability of IQ in America believed to be?

11) If heritability in America is 0.8, and Americans have a mean IQ of 98 with a standard deviation of 15, and each American has an identical twin, born, raised, and gestated in the Third World and their Third World twins have a mean IQ of 75, and an SD of 15; what would be the IQ correlation of the separated identical twins?

12) If heritability in America is 0.8, and Americans have a mean IQ of 98 with a standard deviation of 15, and each American has an identical twin, born, raised, and gestated in the EXACT SAME Third World environment and their twins have a mean IQ of 75; what would be the IQ correlation of the separated identical twins?

13) If the IQ correlation between people in China and their identical twins in Kenya is 0.5, assuming every country has the same environmental variability, what would be the IQ correlation between identical twins separated randomly all over the World if average environmental differences between countries was controlled for?

14) If brain size correlates 0.4 with general intelligence, and natural selection for general intelligence alone caused brain size to increase by 2 standard deviations, by how many standard deviations did general intelligence increase?
