Simulations show politically motivated gerrymandering mostly evens out on a national scale

A group of political scientists from Harvard University, working with a colleague from Yale University, has found via simulations that politically motivated gerrymandering in the U.S. tends to cancel out as both sides change voting borders. In their study, reported in Proceedings of the National Academy of Sciences, Christopher Kenny, Cory McCartan, Tyler Simko, Kosuke Imai and Shiro Kuriwaki used simulations to compare congressional mapping in the U.S. using data from the 2020 census.
