The Zoe Symptoms Study app and the Mass Science app, alongside a range of other platforms, have demonstrated that millions of people are willing to share their sensitive personal information (e.g. symptoms, test history, vaccination status, location, happiness, alertness etc.) with third parties if it is easy to do, their information is secure and they believe they are contributing to public good. Similarly, an increasing number of people are wearing health trackers (e.g. Fitbit) and are willing to share their data with third parties if it is easy to opt in, their information is secure and they believe they are contributing to the common good. The opportunity: charities and government organisations could generate invaluable real-time insight into people’s opinions, preferences, priorities, behaviours, health and wellness (helping them improve services and policy) by extending and building on millions of peoples’ experience self-reporting and sharing their personal information for the public good during the pandemic.
