Social scientists are facing a crisis of confidence in quantitative results. Multiverse analysis provides concerned scholars a tool for verifying the robustness of findings. This article introduces political scientists to multiverse analysis through an application. It identifies how differing approaches to data processing led to divergent conclusions about the representation of lesbian, gay, and bisexual (LGB) Americans in Congress in a 2015 Journal of Politics article. The analysis casts doubt on the original conclusion that the size of the LGB population in a district is significantly associated with the bill sponsorship activity of its representative. More broadly, it demonstrates how researchers can keep a running tally of data-processing decisions and parsimoniously present the consequences of those decisions for the findings. Multiverse analysis can help scholars publish replicable results in original work as well as replicate and extend previously published work. [ABSTRACT FROM AUTHOR]

If politicians in the United States were paid better, would more middle- and working-class people become politicians? Reformers often argue that the low salaries paid in state and local governments make holding office economically infeasible for lower-income citizens and contribute to the enduring numerical under-representation of the working class in our political institutions. Of course, raising politicians’ salaries could also make political office more attractive to affluent professionals, increasing competition for office and ultimately discouraging lower-income citizens from running and winning. In this article, we test these hypotheses using data on the salaries and economic backgrounds of state legislators. Contrary to the notion that paying politicians more promotes economic diversity, we find that the descriptive representation of the working class is the same or worse in states that pay legislators higher salaries. These findings have important implications for research on descriptive representation, political compensation, and political inequality. [ABSTRACT FROM PUBLISHER]
