It’s a hard lot being a human, these psychologists explain. You walk around with the knowledge that the world is fundamentally uncaring, that no matter how hard you work there is no promise of success, that you are competing against billions, that you are vulnerable to the elements, and that everything you ever love will eventually be destroyed. A little lie can take the edge off, can help you keep charging forward into the gauntlet of life, where you sometimes, accidentally, prevail.
