Over the past year, public health officials went from being the people who nudge us not to smoke, not to drink and drive, and to eat our veggies, to being a highly visible arm of government involved in calling a lot of the shots: which businesses could stay open and which had to close; who could go to work or be in school; ordering people to cover their noses and mouths. Public health became powerful. Many people looked to them to keep all of us safe — others have felt suspicious and resentful. Like — who are these people to tell us what to do? To restrict our rights? Can we trust them? Trust has become a major issue of our time — trust in information, in government, in science, and in public officials.

Last week, we explored scientific research and trust. On this episode — the second part of our deep dive into trust — we look at public health, and how they talk to us, the public. What gets people’s attention and cooperation? What creates resentment and rebellion? Do public health officials have an obligation to be totally transparent — or to do whatever it takes to keep the public safe?

Also heard on this week’s episode:
