One of the difficulties with interpreting group-differences in intelligence, is that these studies are almost all
A) experimental.
B) correlational.
C) biased.
D) unfalsifiable.
Answer: B
Rationale: Group-differences research on intelligence is almost entirely correlational—it is just not possible to conduct randomized experiments (e.g., randomly assigning someone to a certain socioeconomic class, for example). Correlations do not provide evidence for cause-and-effect relationships. Therefore, we should not assume that the genetic patterns that contribute to a particular race also account for differences in intelligence.
