Id pay special attention to Study 4 which seems to really hit my key points of criticism as a layman. Study 4 controlled for census region but I’d really like to see this controlled for rural vs urban populations at a finer scale. Without that adjustment I question the validity of other studies included.
That said study 4, if I’m reading it right, still found a correlation with happiness in conservatives but that correlation did not survive when religion was accounted for. Which tells you everything you need to know.
The conservatism isn’t the primary ideology, this is just a roundabout way of asking if religious people report being happier and having more meaning and of course they do. The religious aspect almost overrules the political angle entirely.
Consumers don’t relate low inflation to bad inflation but as you can see the fed wasn’t able to hit its target all of 2020. That’s a really bad sign by itself, the US is very lucky that it never got a true recession/depression.
