Statistically Valid Inferences from Privacy Protected Data (Harvard, Privacy Tools Project), at Harvard University (via Zoom), Monday, April 20, 2020:

Unprecedented quantities of data that could help social scientists understand and ameliorate the challenges of human society are presently locked away inside companies, governments, and other organizations, in part because of worries about privacy violations. We address this problem with a general-purpose data access and analysis system with mathematical guarantees of privacy for individuals who may be represented in the data, statistical guarantees for researchers seeking insights from it, and protection for society from some fallacious scientific conclusions. We build on the standard...

Simplifying Matching Methods for Causal Inference (Hebrew University of Jerusalem) Wednesday, January 1, 2020:
We show how to use matching methods for causal inference to ameliorate model dependence -- where small, indefensible changes in model specification have large impacts on our conclusions. We introduce methods that are simpler, more powerful, and easier to understand than existing approaches. We also show that propensity score matching, an enormously popular approach, often accomplishes the opposite of its intended goal -- increasing imbalance, inefficiency, model dependence, and bias -- and should be replaced with other matching methods in applications.  See ...

Statistically Valid Inferences from Privacy Protected Data (University of Chicago) Friday, November 8, 2019:
The vast majority of data that could help social scientists understand and ameliorate the challenges of human society is presently locked away inside companies, in part because of worries about privacy violations. We address this problem with a general-purpose data access and analysis system with mathematical guarantees of privacy for individuals who may be represented in the data, statistical guarantees for researchers seeking insights from it, and protection for society from some fallacious scientific conclusions. We build on the standard of ``differential privacy'' but, unlike most such... Read more about Statistically Valid Inferences from Privacy Protected Data (University of Chicago)
How to Measure Legislative District Compactness If You Only Know it When You See it (University of Chicago) Thursday, November 7, 2019:

To deter gerrymandering, many state constitutions require legislative districts to be "compact." Yet, the law offers few precise definitions other than "you know it when you see it," which effectively implies a common understanding of the concept. In contrast, academics have shown that compactness has multiple dimensions and have generated many conflicting measures. We hypothesize that both are correct -- that compactness is complex and multidimensional, but a common understanding exists across people. We develop a survey to elicit this understanding, with high reliability (in data where...
