At first this seemed high considering the amount of work already done by Google/Apple, but I remembered that the German government must also put together the infrastructure that temporarily houses all the matching data (between those infected and those who they contacted).
Of course we can see the cognitive dissonance between those who do not trust the app but feel comfortable sharing deeply personal information on social media networks. I’m sure there are even those who do not trust this app but have volunteered their genetic information to 23andme.
On one hand, that’s frustrating. On the other, I’m not sure how we can expect anything different. There is absolutely no formal education on this subject for children or adults in the United States. Congress has been passing digital privacy legislation for over a half century and it seems largely ineffective. Most likely because lawmakers also don’t understand the issue very well.
Your informal survey is pretty interesting. On your first group, I’ve found even when I try and educate friends and family who trust me on this issue, they still don’t feel like they have enough information. It seems like it’s not a one-shot fix. The education problem is broad; the app is a symptom.
