ANN ARBOR, Mich. – As of Saturday, Michigan lifted mask requirements for most indoor and outdoor settings for fully vaccinated residents. The move matches newly issued guidance from the CDC.

There is no way to tell who is vaccinated and who is not, which puts Michigan residents on an honor system. A University of Michigan researcher spoke with Local 4 about how to make the right choice and trust people around you are doing the same.

There is growing concern that more people will choose to not get vaccinated against COVID.

“It does depend on the type and the format of the information that people are getting. So sometimes we’re pretty good and sometimes we’re really not so great,” psychologist Josh Ackerman said.
