Explanation

This question is asking for the identification of true and false statements about race and IQ. The statements provided are about the comparison of IQ scores between different racial groups, the influence of environmental factors on IQ, and the perspectives of sociologists on IQ-based explanations for racial differences.1. "As a group, Blacks have lower IQ scores than Whites." - This statement is generally considered to be true, as numerous studies have shown that, on average, Black individuals tend to score lower on IQ tests than White individuals. However, it is important to note that these differences are often attributed to socio-economic factors and educational opportunities rather than inherent racial differences.2. "Sociologists give little weight to IQ-based explanations for racial differences." - This statement is also true. Sociologists generally focus on socio-economic and environmental factors when explaining racial differences in IQ scores, rather than attributing these differences to inherent racial characteristics.3. "The gap between Black and White IQ scores has remained steady for many decades." - This statement is false. Research has shown that the gap between Black and White IQ scores has actually been decreasing over time, largely due to improvements in educational opportunities and socio-economic conditions for Black individuals.4. "Environmental influences affect individuals' IQs." - This statement is true. Numerous studies have shown that environmental factors, such as educational opportunities, socio-economic status, and access to resources, can have a significant impact on an individual's IQ score.
