Conservatives Are Happier, and Extremists Are Happiest of All - NYTimes.com
Well, I made the retired part up, but I really suspect it us true.
Not a lot of new news here, people are happier when they know where they fit and have solid relationships in that fit -- which the more extreme you are, the more likely you are to hang together. Flat Earthers and Moon Landing Deniers soon end up finding each other in the internet age.
Turns out that actual multiple thousand year old religions tend to work a lot better than those thought up yesterday in the happiness department.
Should we care? Well, I'd argue that we don't have a choice -- we are wired to seek happiness, it really isn't an option for this relrase of humanity.
