Jerry Wei will present his MSE thesis talk "Browser Beware: An Empirical Study of Disinformation Warning Effectiveness" on Wednesday, May 8, 2019 at 1:30pm in CS 402. The members of his committee are Jonathan Mayer (adviser) and Marshini Chetty.. Everyone is invited to attend his talk. His abstract follows below. We present the first-of-its-kind user experience study to assess whether browser warnings are effective measures for preventing users from accessing disinformation websites. Current browser warning research has focused on the use of warnings to protect users from malware, phising, and security vulnerabilities. We create warnings in Google Chrome that caution users against disinformation by adapting the existing security warnings, and conduct a laboratory experiment to examine users’ reactions when they encounter disinformation sites. To our knowledge, we present the first in-depth field study of browser disinformation warnings, and their impact on user behavior.
