I think there's a big problem in science that a lot of of public facing is done by people who are not scientists or are the kind of scientists that no longer care about science. The reason for this is that people feel and scientists feel like they cannot communicate with each other.
With this in mind, you end up in a scenario where there's a lot of miscommunication happening with the scientist side promising things that are impossible or reducing the complexity of things to a point where the science that was done doesn't make much sense anymore.
I think there is really a need for better communication, humility might come from the perspective that scientists need to admit this is a problem. It's not that the people are dumb it's that academics are failing at educating them.
