[Does Rumination Have A Purpose?]

Excerpts:

The alternative, of course, is that depression has a secret purpose and our medical interventions are making a bad situation even worse. Like a fever that helps the immune system fight off infection — increased body temperature sends white blood cells into overdrive — depression might be an unpleasant yet adaptive response to affliction. Maybe Darwin was right. We suffer — we suffer terribly — but we don’t suffer in vain.

In the late 1990s, Thomson became interested in evolutionary psychology, which tries to explain the features of the human mind in terms of natural selection. The starting premise of the field is that the brain has a vast evolutionary history, and that this history shapes human nature. We are not a blank slate but a byproduct of imperfect adaptations, stuck with a mind that was designed to meet the needs of Pleistocene hunter-gatherers on the African savanna. While the specifics of evolutionary psychology remain controversial — it’s never easy proving theories about the distant past — its underlying assumption is largely accepted by mainstream scientists. There is no longer much debate over whether evolution sculptured the fleshy machine inside our head. Instead, researchers have moved on to new questions like when and how this sculpturing happened and which of our mental traits are adaptations and which are accidents.


... research has reinforced the view that rumination is a useless kind of pessimism, a perfect waste of mental energy. ...
That, at least, was the scientific consensus when Andrews and Thomson began exploring the depression paradox. Their evolutionary perspective, however — they see the mind as a fine-tuned machine that is not prone to pointless programming bugs — led them to wonder if rumination had a purpose.
