Saved information is remembered less well than deleted information, if the saving process is perceived as reliable.

Memory 2021 Aug 2:1-10. Epub 2021 Aug 2.

Department of Psychology, University of California, Santa Cruz, CA, USA.

Prior research has shown that people are more likely to remember information that is deleted from a computer than information that is saved on a computer, presumably because saving serves as a form of cognitive offloading. Given recent concerns about the robustness and replicability of this "Google Effect," we conducted two experiments seeking to replicate and extend the phenomenon by identifying a potential boundary condition for when it is observed. In Experiment 1, we replicated the Google Effect, but only when participants experienced a practice phase demonstrating the reliability of the saving process. Read More

Democracies Linked To Greater Universal Health Coverage Compared With Autocracies, Even In An Economic Recession.

Health Aff (Millwood) 2021 Aug;40(8):1234-1242

Thomas J. Bollyky is the director of the Global Health Program, Council on Foreign Relations.

Despite widespread recognition that universal health coverage is a political choice, the roles that a country's political system plays in ensuring essential health services and minimizing financial risk remain poorly understood. Identifying the political determinants of universal health coverage is important for continued progress, and understanding the roles of political systems is particularly valuable in a global economic recession, which tests the continued commitment of nations to protecting their health of its citizens and to shielding them from financial risk. We measured the associations that democracy has with universal health coverage and government health spending in 170 countries during the period 1990-2019. Read More
