Recall that in the 1930s, when anti-Asian prejudice was commonplace in the United States, LaPiere (1934) had no trouble finding pleasant accommodations for himself and his Chinese traveling companions

Surprised, LaPiere later sent letters to the establishments they visited, asking whether Chinese visitors would be welcome. More than 90 percent of those who responded replied that they definitely would not accommodate Chinese. Although LaPiere's study suggests that there is a weak link between attitudes and behavior, his results should be interpreted with caution. Why? a. Later, more systematic research revealed that there is generally a strong relation between attitudes and behavior. b. Prejudice has generally declined in the United States since the 1930s. c. His sample of proprietors was not randomly selected. d. Proprietors' attitudes might have changed between LaPiere's visit and the time he sent the letters.
