I flagged it, too, because them calling this a "conservative estimate" makes it very likely that this is on the standard level of the COVID-related junk science. Edit: I was trying to dive deeper to call this out more specifically, but can't get over this quote in the introduction: > e.g., because they don’t take contact tracers seriously, distrust the government, are afraid of scams, social stigma, or have other privacy and cybersecurity concerns If these really are the reasons why you think people refused to participate in contact tracing schemes, you're probably too far removed from other parts of the population to make predictions about their behaviour.
