Final answer:
In the early 20th century, poor test scores among immigrants who were not of Anglo Saxon Heritage were attributed to cultural bias by some psychologists.
Step-by-step explanation:
In the early 20th century, the US government developed Intelligence test to evaluate new year arriving immigrants. Poor test scores among immigrants who are not of Anglo Saxon Heritage were attributed by some psychologists of that day to cultural bias. The idea was that the tests were biased towards individuals from Western Europe and did not take into account the cultural knowledge and experiences of immigrants from other regions. It was believed that these immigrants were at a disadvantage on the test not because of any inherent mental inferiority, but because of the testing methods themselves.
