I sometimes have thoughts of suicide. That does not mean I would ever come within a mile of committing the act of suicide. But my brain does simulate it; though I do try to always reduce such thoughts.
But what I have noticed is that 'suicide' is triggered in my mind whenever I think of some embarrassing event, real or imagined. Or an event in which I'm obviously a low-status actor. This leads me to think that suicide might be a high-status move, in the sense that its goal is to recover status after some event which caused a big drop in status. Consider the following instances when suicide is often considered:
- One-sided break-ups of romantic relationships. The party who has been 'dumped' (for the lack of a better word), has obviously taken a giant status hit. In this case, suicide is often threatened.
- A samurai committing seppuku. The samurai has lost in battle. Clearly, a huge drop in status (aka 'honor').
- PhD student says he/she can't take it anymore. A PhD is a constant hit in status: you aren't smart enough, you don't have much money, and you don't yet have intellectual status.
I see suicide as often a reaction to the pain of a decrease in status, particularly when the status decrease is believe to be permanent.
I'd suggest, however, that much of the pain of the status change is temporary. I've had my own setbacks. The new lower status state is not so fearsome and horrible that it can't be faced. It's refusing to face the change that prolongs the pain. Suicide is a strategy to evade the pain of the evasion of the truth.
