Privileged individuals (those from high socioeconomic statuses) tend to come from resource-rich environments that don't vary as much as the environments of individuals from more diverse backgrounds. What does this predict about heritability estimates of IQ? A. Heritability estimates should be higher in privileged groups than in more diverse groups B. Heritability estimates should be higher in more diverse groups than in privileged groups C. Heritability estimates should not differ between groups, but estimates of the contribution of the shared environment should be higher in privileged compared to diverse groups D. Heritability estimates should not differ between groups, but estimates of the contribution of the shared environment should be higher in diverse compared to privileged groups
