NB: Participating in this study requires an Android or Apple smartphone with a Play or App store account. Big Sister is not publicly available; you will be invited to download the app via this account. This app generates inferences about your personality using data you provide by linking a Twitter or Facebook account, or by processing a text you have written yourself. It provides music recommendations through a linked Spotify account. If you participate, any data you share through these services will be stored on your device. This data will be processed for non-commercial academic purposes and will not be shared with third parties.

Do you use these digital platforms to discover new products, like books, songs, movies, television shows, etc, by following their algorithmic recommendations? These include the “Discover” feature on Spotify, for example.

The following questions will provide us with some more information about who you are so that we can ensure that we recruit a representative sample of participants for our study. This data will be retained on Warwick servers and will only be used for academic purposes.

Please provide us with an email address so that we can contact you about participating in our research project
