confirmation bias
Confirmation bias is a ritual in which we lavishly offer the dearest fragments of reality to the altar of our preconceptions, meticulously ignoring any inconvenient truths. It handpicks agreeable evidence and dismisses dissenting facts with the efficiency of a seasoned bouncer. In our minds, we become sagacious arbiters of truth; to others, we are merely stubborn architects of self-deception. When defending our beliefs, we see only what pleases us and hear only what flatters us.
