What these two world views, pop psychology and religion, have in common is a deep-seated need for meaning and order, for a system or a narrative that makes sense of the world. The idea that maybe nothing happens for a reason is deeply unsettling to many people. For the rationalist, regretting past events or actions is tantamount to admitting to the terrifying possibility that failing is as easy as knocking over a glass. Goal-based decision-making gives structure to what would otherwise be a series of random events, and accomplishing those goals gives the illusion of meaning. The idea that it’s always preferable to keep your eyes trained on the future, to look on the bright side, and to let go and let God take over is deeply ingrained in both rational and religious world views.
