This paper takes issue with the trend to attribute differences in economic growth rates to differences in interpersonal trust. I discuss the World Values Survey (WVS) measure that is used to operationalise trust at the macro level. I hypothesise that there is a mismatch between the theoretical argument and the empirical operationalisation of trust. Instead of measuring trust, the WVS measure may instead proxy the well-functioning of institutions. I provide circumstantial evidence for this thesis by a principal components analysis of trust and institutions and a robustness test of Zak and Knack's (2001. Trust and growth, Economic Journal, vol. 111, 295–321) seminal study on trust and economic growth.
