> though the technology worked relatively well, people did not respond well to being told to isolate by an app. I would have thought that this depends a lot on the nature of said "message". It needs to be a personal decision based on evidence you make available to the individual. For example - if you were to send a message like - here is a photo of you on a bus, this person sitting next to you has tested positive, you sat next to them for 25 minutes - then sure, people will likely take action based on that. The Government sending a message saying "you need to stay indoors for 2 weeks now because computer said so" is just not compatible with most people's world view, of course that's going to be completely ignored, it's arbitrary house arrest. It also doesn't help that the UK Government are acting like circus clowns, people are going to say things like "Boris told me to stay indoors, but I needed to test my eyesight[1]".
