A demonstrated and strong correlation exists between intelligence and depression. In some respects, I believe this correlation to be so strong it functions as a natural barrier to how smart humans can be, at least without concurrent evolution of alternate brain structures. I traditionally justified this correlation by stating: “The world is a pretty tragic place. The smarter one is, the more one realizes this.” And I stand by this assessment. But of late I’ve been thinking a lot, (which I’ll admit is also usually somewhat detrimental to my overall happiness) and have come up with another, potentially even more causative reason: the smarter one is, the more one recognizes the complete lack of control one has over one’s life.
A sense of control, moreover, is fundamental to our happiness. Why this is may not be clear, but that it is has been fairly conclusively proven (Tara Hunt, who *OMG I actually know IRL!*, has a lovely post on the issue here). If only as a defense mechanism, most of us spend our days imagining we have at least some control over our futures. But for all people, no matter how wealthy or powerful they may be, this sense of control is largely illusionary; random factors far beyond an individual’s scope have as great or greater an impact on their lives than anything within their realm of influence. The better informed one is, the more one knows about the world and one’s place in it, the more difficult it is to maintain this illusion. And thus, yet another trip down Depression Lane. (It’s near Sesame St., and adjacent to Melancholy Alley.)
Zen Buddhism, most notably, attempts to challenge this biological precept by suggesting that practitioners should learn to accept a lack of control over their destinies. For some this may be possible; for others, given how much this tenet conflicts with ingrained biology, I’m not as confident. Still, it’s a lovely concept, and if it doesn’t work out I hear there’s a great new chocolatier at the intersection of Depression and Self Destruction, right next to the tobacconist.
