@Ratel, I think I disagree. It’s late already, will revisit tomorrow if I can.
Short reply:
at least in my cultural surrounding, plenty of people will take the app not as an indicator, a warning, but as the truth. Hence, no warning, no problems. Which is terrible for false negatives. Warning, problem. Which is very inconvenient for false positives. And false positives will be massive, if you want to reduce false negatives. It is a trade-off. And it will cause massive problems like this.
I think we will be worse off like this.
Additionally, it undermines the credibility of everyone advocating BT contact tracing now. Which is quite bad, since some virologist do, quite possibly trusting the technological advice they got from people who should have the same info @Aciantis posted, but apparently came to a different conclusion.
I still haven’t found one sound explanation why it should word, besides the arguments brought forth in this topic… Which worries me no end.
