The same Atlantic article mentioned below continued with this unique thought:
Pretty much no matter how you test it, children make us less happy. The evidence isn’t just from diary studies; surveys of marital satisfaction show that couples tend to start off happy, get less happy when they have kids, and become happy again only once the kids leave the house. As the psychologist Daniel Gilbert puts it, “Despite what we read in the popular press, the only known symptom of ‘empty-nest syndrome’ is increased smiling.” So why do people believe that children give them so much pleasure? Gilbert sees it as an illusion, a failure of affective forecasting. Society’s needs are served when people believe that having children is a good thing, so we are deluged with images and stories about how wonderful kids are. We think they make us happy, though they actually don’t.
The ‘multiplicy of self’ theory would posit the following answer:
There is no inconsistency between someone’s anxiously hiking through the Amazon wishing she were home in a warm bath and, weeks later, feeling good about being the sort of adventurous soul who goes into the rain forest. In an important sense, the person in the Amazon is not the same person as the one back home safely recalling the experience, just as the person who honestly believes that his children are the great joy in his life might not be the same person who finds them terribly annoying when he’s actually with them.
Any thoughts? I’m not so sure.
