Editor's Choice Understanding context effects for a measure of life evaluation: how responses matter
研究发现，调查中先问政治问题会降低受访者的生活评价，且不同人群受影响方式不同，如老年人评价相对提高、非裔美国人因被问及奥巴马表现而评价上升。
We study context effects on responses to wellbeing questions. We find that those who were randomized into being asked a series of political questions subsequently report lower life evaluation; those who were previously asked about their evaluation of the direction of the United States lowered their own life evaluation, but only if they disapproved of the way the country was going. Subgroups of the population are affected in different ways; the age profile of wellbeing is tipped in favor of the elderly, and African American’s life evaluations are increased when they are asked about President Obama’s performance. The context effects are large, not easily removed, and change wellbeing rankings across groups.
