Final answer:
Sir Francis Galton's intelligence tests had problems such as cultural bias, largely favoring students with knowledge linked to upper-class culture, which does not accurately measure intelligence across different demographics.
Step-by-step explanation:
The problem with Sir Francis Galton's intelligence tests is that they were biased towards certain cultural groups. This means that the tests tended to reward affluent students with questions that assumed knowledge associated with upper-class culture. Consequently, these tests potentially measured cultural knowledge rather than actual intelligence, as conflicts theorists suggest. This cultural bias was evident in items such as asking which instruments belong in an orchestra, a question that assumes a certain level of cultural exposure. Moreover, there are references indicating that Galton's views also included problematic assumptions about the inheritance of intelligence and its correlation with race, variables such as socioeconomic status were not accounted for as influentially as they are recognized to be today.
