This seems to me an ineffective way of seeking to dismiss our natural responses to horror and tragedy, and it can be viewed as a variation on the widespread belief in a "just world," a concept first explored by psychologist Melvin Lerner:
Individuals have a need to believe that they live in a world where people generally get what they deserve.
Since the belief that the world is just serves such an important adaptive function for the individual, people are very reluctant to give up this belief, and they can be greatly troubled if they encounter evidence that suggests that the world is not really just or orderly after all.
And I'm reminded of something I wrote on February 8th, the last day I saw my friend Erik, reflecting on mortality without grasping just how close at hand it was: "I find myself considering how I spend my time--and with whom--and the image of a candle burning down readily comes to mind.
Instead of adding items to a 'bucket list,' I feel motivated to let things go, to devote less and less time to activities I find unrewarding, and to focus my energy on the people and experiences I find most meaningful."
