Starting today in the US, some people will see a link at the top of News Feed to an optional, off-Facebook survey to help health researchers better monitor and forecast the spread of COVID-19. The survey — run by Carnegie Mellon University Delphi Research Center — will be used to generate new insights on how to respond to the crisis, including heat maps of self-reported symptoms. This information can help health systems plan where resources are needed and potentially when, where and how to reopen parts of society. If the results are helpful, we’ll make similar surveys available in other parts of the world.
CMU Delphi Research won’t share individual survey responses with Facebook, and Facebook won’t share information about who you are with the researchers. To help them measure results while protecting your privacy, we’ll share a random ID number that CMU will send back to us when someone completes the survey. Then we’ll share a single statistic known as a weight value that doesn’t identify you but helps correct for any sample bias.
