Replication: The Effect of Differential Privacy Communication on German Users'...
summary
Replication of Xiong et al. 2020 runs two online experiments with n ≈ 728 Germans and tests 11 wording variants of differential privacy; participants do not distinguish global model from local model, about 50% share sensitive data, and only ~13% report difficulty though five-question comprehension scores are very low. Willingness to share rises for health-app users and for people who spend ~3 minutes reading a description; overall results show homogeneous responses and call for clearer metaphors and graphics.
