Research on right populist support and redistribution preferences increasingly argues for the explanatory power of subjective over objective social position. However, scrutiny of a widely used measure underlying such findings is lacking. I provide a multifaceted assessment of the Top–Bottom Self-Placement question (“Topbot”), which is primarily used in the International Social Survey Programme. Through 36 cognitive interviews and analysis of secondary data sets, I evaluate Topbot’s psychometric qualities, how it is interpreted by respondents, and how far this corresponds to the (contradictory) interpretations assumed by researchers. Consonant with findings of low reliability and high, non-random non-response when a “Don’t know” option is available, the interviews highlight that Topbot is worded ambiguously, leading to varied interpretations and often puzzlement. The most frequently mentioned bases of self-placement represent economic resources. Clustering of responses in the middle is widely known; interviews reveal explanations beyond misestimation. As additionally evidenced by convergent validity analyses, interpretations of Topbot as measuring perceived income decile or subjective social status in a specifically Weberian sense are untenable, and empirical claims made on these bases should be revisited.
