While facts can be verified or refuted—and we should do so expeditiously and relentlessly—we must also recognize the possibility that more complex truths are often in the eyes of the beholder. This fact of human cognition doesn’t necessarily imply that relativism is correct or desirable; not all truths are equally valid. But because the particular narrative that one adopts can color and influence the subsequent course of inquiry and debate, we should strive at the outset to entertain as many interpretations of the same set of objective facts as we can, and hope that a more nuanced and internally consistent understanding of the crisis emerges in the fullness of time.
