Interesting findings. I think it’s interesting that the decline in religiosity seems to be more lack of trust in religious institutions, rather than just non-belief. I’m curious how this will affect organized religions. It seems religion is becoming more personal, with less of a social aspect, for better or worse.
Organized religion has same issues as most human organizations. Organizations tend to develop a life if their own and do not always serve their customers or other stakeholders and can do things that are counter productive. They also can develop a internal power structure run by people seeking their own ends.
