A rich theoretical literature argues that, in contradiction to the Duverger’s law, the plurality voting rule can fail to produce two-party system when voters do not share common information about the electoral situation. We present an empirical operationalization and a series of tests of this informational hypothesis in the case of India using constituency- and individual-level data. In highly illiterate constituencies where access to information and information-sharing among voters is low, voters often fail to coordinate on the two most viable parties. In highly literate constituencies, voters are far more successful at avoiding vote-wasting – in line with the informational hypothesis. At a micro-level, these aggregate-level patterns are driven by the interaction of individual information and the informational context: in dense informational environments, even low-information voters can successfully identify viable parties and vote for them, but in sparse informational environments, individual access to information is essential for successful strategic voting.
