I was always skeptical about this. A lot of people claimed people needed this motivation, especially the masks. That may be true of some people but it was usually discussed a rash of people would just do it. That isn't what is happening. What's happening, which is why I made sure to quote the part I did with the article another poster linked, is that people who didn't want to get vaccinated or were on the fence, still aren't but now they get to do mostly what they wanted..without having to get vaccinated. The motivation is actually lower for those people not higher. I kinda expected that to be the outcome. I haven't really heard from people much that the adjustment in mask wearing guidance for fully vaccinated has made the people they knew in real life to go get the vaccine. It really just placed businesses and states in this weird position of pressure to remove/reduce requirements without holding the unvaccinated accountable.
I think the most motivators are going to come from the local efforts but I don't know how successful they will be. I do agree with the larger point many have been making, hard to come back from these types of guidelines and I think we kinda expected that (especially with the masks). Compliance to get people to go back to that was always going to be an issue once you let it go.
