If everyone knew about this, democracy might be more effective. We would only elect depressed people to positions of power, favoring their superior acumen. The most convincing speeches would be nihilist considerations on the uselessness of trying and the futility of life, then we would know, "this is the one who sees things as they are". One issue, though, might be that the military commander in chief might try to use that power against themselves.

Edit: Reading further into the article, it seems my utopia is actually unrealistic, how unfortunate.
