Religion and Subjective Well-Being

Could be personality factors. Subjective is the key word, isn't it?

Yes, I agree. Could it be that the personality types that are attracted to religion are just more positive/happy?

Yes. Personality types is often overlooked in many questions.

Some people are actually happy that they exercise daily. I've often wondered if it's the exercise making them happy. It seems possible happy people like to exercise. I make that up on the spur of the moment, but you kind of get the idea.

I often hear that too from people that exercise regularly. They state that it makes them happy and I have also wondered if they are already happy and just more motivated to exercise because of this positive personality trait....thank you for your response...

I would imagine that anyone who engages meaningfully with a long-term hobby or passion would report much the same. Just my guess, but maybe people who don't report such well-being are at least to some extent those who are prevented from engaging passionately in something that they chose. Maybe nobody ever encouraged them to cultivate such an interest, or maybe they just gave it up for work or family or something else. Hard to say for sure. Like, roger, I just made that up.

You say "from what i have read." Where did you read it? If it refers to a study, what was their methodology? Could someone have gone looking for a confirmation of their bias, and--wonder of wonders--have found it?

I would be surprised if that was actually the case. Do you remember where you read it?
