A personality psychologist is interested if being a snob is heritable. To answer this question a personality psychologist recruits a huge sample of 2,593 identical twins and found that identical twins were similar in how snobby they were with an effect size of r=0.56. They also recruit a huge sample of 1,845 fraternal twins and found that fraternal twins were also similar in how snobby they were with an effect size of r=0.35. Calculate the heritability coefficient for being a snob. Remember that your data here is made up, so please don't tell your friends about how heritable their snobbishness is? Now interpret the heritability coefficient you just calculated in plain English.
