This Counterpoint investigates the continued relevance of the 30-year-old Kogut and Singh (KS) index of cultural distance. KS was a seminal contribution, highlighting the relevance of cultural differences in IB. However, since then, simplistic replications of the original arguments and index have prevented us from progressing towards a better understanding of how cross-national differences matter. We discuss the mechanisms underlying the construct and how they relate to the algorithm, data, and its critiques. We call for more theoretically informed approaches, highlighting the underlying mechanisms, and specifying which data and algorithms best capture those mechanisms in each research context.
