Depression as an adaptation

According to the latest edition of Scientific American Mind, new research suggests that depression is not necessarily a a disease or aberration. In many cases, having a depression might increase your chances of survival.

[D]epression should not be thought of as a disorder at all. In an article recently published in Psychological Review, we argue that depression is in fact an adaptation, a state of mind which brings real costs, but also brings real benefits.
The researchers go out of their way to acknowledge that depression is a terrible problem for many people who should seek out help. Nonetheless, they also suggest that the mode of thinking characteristic of many bouts of depression is focused, highly analytical and systematic:

Analysis requires a lot of uninterrupted thought, and depression coordinates many changes in the body to help people analyze their problems without getting distracted . . . [D]epression is nature’s way of telling you that you’ve got complex social problems that the mind is intent on solving. Therapies should try to encourage depressive rumination rather than try to stop it, and they should focus on trying to help people solve the problems that trigger their bouts of depression . . . [D]epression . . . seems . . . like the vertebrate eye—an intricate, highly organized piece of machinery that performs a specific function.

For further reference: I first rand in to this idea that many bouts of depression might be useful in a book called Why We Get Sick, by Randolf Nesse.

Exercise great caution when peeling back the skin of life.

As human animals, we are condemned to live with great ignorance in an unpredictably violent world.  To compensate, most of us work hard to develop an extraordinary expertise to protect ourselves from considering our precarious existence.  We work hard to pre-screen toxic thoughts.  We rarely contemplate our own inevitable deaths, for example.  We are often successful at protecting ourselves from real-life things that would terrify us if we dared to squarely consider them.

Once in a while, though, we get a terrifying glimpse of unvarnished reality.  For instance, we sometimes suddenly realize that we are affixed to that Conveyor Belt of Life, a “belt” that inexorably moves us toward a time when we will be old if we’re lucky, then lifeless.  Whenever this terrible thought brings shivers, we quickly change channels to consider something less macabre.  Yet we are all strapped onto that Conveyor Belt, even our precious young children.  In 150 years, everyone currently living on Earth will be dead.  It is difficult to conjure up more disturbing thoughts.

What other toxic thoughts occur when our mental guard is down?  How about the thought that we are not meaningfully different from each other.  Or that the world is full of mobile intestinal tracts–walking talking intestinal tracts.  Or that our bodies are rife with parasites. And that we are animals. Or that we are breathing, thinking meat, a point directly yet elegantly made by a touring entourage of corpses known as BodyWorlds.  And here’s another toxic truth most of …
