Dr Nesse’s hypothesis is that, as pain stops you doing damaging physical things, so low mood stops you doing damaging mental ones—in particular, pursuing unreachable goals. Pursuing such goals is a waste of energy and resources. Therefore, he argues, there is likely to be an evolved mechanism that identifies certain goals as unattainable and inhibits their pursuit—and he believes that low mood is at least part of that mechanism.
So depression helps to stop you being a persistent jerk in chasing that unattainable partner, for example,
It is a neat hypothesis, but is it true? A study published in this month’s issue of the Journal of Personality and Social Psychology suggests it might be. Carsten Wrosch from Concordia University in Montreal and Gregory Miller of the University of British Columbia studied depression in teenage girls. They measured the “goal adjustment capacities” of 97 girls aged 15-19 over the course of 19 months. They asked the participants questions about their ability to disengage from unattainable goals and to re-engage with new goals. They also asked about a range of symptoms associated with depression, and tracked how these changed over the course of the study.
In a society that places enormous value on 'succeeding at your goals', might this lead to further depression, or that happy poverty is somewhat due to knowing nearly any goal is pretty much beyond one's reach?
Dr Nesse believes that persistence is a reason for the exceptional level of clinical depression in America—the country that has the highest depression rate in the world. “Persistence is part of the American way of life,” he says. “People here are often driven to pursue overly ambitious goals, which then can lead to depression.” He admits that this is still an unproven hypothesis, but it is one worth considering. Depression may turn out to be an inevitable price of living in a dynamic society.
For myself, I've never suffered from depression, perhaps I give up too easily though most friends would say I'm pathologically stupid in believing I can do anything, which sort of fits the hypothesis as well,
What thinks NSG?
