 Similarly, Schwarz has found that when a question about marital satisfaction precedes a question about general life satisfaction, responses for the two questions are highly correlated because the first question renders information about one's marriage highly accessible, but other studies have found the same correlation when the marital satisfaction question is asked after the general life satisfaction question, presumably because marital satisfaction is chronically accessible.Schwarz also found that this correlation vanishes when the two questions are framed as subordinate parts of a larger question, presumably because the respondent infers that the interviewer does not want redundant information and thus marital satisfaction should be specifically subtracted from general life satisfaction.Similar reasoning has been applied to understanding the relation between people's ratings of social groups' central tendency and variability.
