The Greater Good Science Center helps sponsor research on social and emotional well-being ("the science for a meaningful life"). But don't take my word for it. Check it out.
I got involved through the Raising Happiness blog, written by Dr. Christine Carter, who was very influential as I wrote my thesis on the language used in parenting books. (The thesis for which I won a fancy-sounding prize). I'm a fan because I like the way she explains the research and applies it in a practical way.
My affiliation is as a volunteer and as editor of the weekly community Gratitude Journal. Check it out: here.
