Two key features robustly describe ideological differences in society: (i) individuals persistently disagree about objective facts; (ii) individuals also disagree about which sources can be trusted to provide reliable information about these facts. We develop a model in which these patterns arise endogenously as the result of small deviations from Bayesian information processing. Individuals re...

American politics has become more polarized. The source of the phenomena is debated. We posit that human mate choice may play a role in the process. Spouses are highly correlated in their political preferences, and research in behavioral genetics, neuroscience, and endocrinology shows that political preferences develop through a complex interaction of social upbringing, life experience, immedia...

We present a formal model explaining that US presidents strategically unionize federal employees to reduce bureaucratic turnover and ‘anchor’ the ideological composition of like-minded agency workforces. To test our model’s predictions, we advance a method of estimating bureaucratic ideology via the campaign contributions of federal employees; we then use these bureaucratic ideal point estimate...

The Semple antirabies vaccine was developed by David Semple in India in 1911. Semple introduced a peculiarly British approach within the Pasteurian tradition by using carbolized dead virus. This article studies this unique phase of vaccine research between 1910 and 1935 to show that in the debates and laboratory experiments around the potency and safety of vaccines, categories like "living" and...

Critics of Hindutva nationalism see it as either an elite conspiracy or a mass political movement with no necessary relation to the Hindu faith. I focus instead on its ideological deployment, treating it as a modern religious construction of Hinduism that legitimates capitalism—much like Christianity in the 17th and 18th century. I mobilize Slavoj Žižek, Erenesto Laclau, and Louis Althusser’s t...

Political sophistication is a concept that encompasses political reasoning, the coherence of people's issue attitudes, and their knowledge of political processes. To what extent is political sophistication affected by genes and environments? Do these distinct but related measures of sophistication share a common genetic structure? We analyze survey data collected from participants in the Minnes...
