What would Epicurus think about how "confirmation bias" describes our underlying tendency to notice, focus on, and give greater credence to evidence that aligns with our existing beliefs.
When forming judgments, confirmation bias causes us to selectively gather information based on what we already believe. Because this often occurs unconsciously, it can shape how we see the world completely outside our awareness. Even when we encounter evidence that might contradict our beliefs, we tend to interpret this new information in a way that still supports what we think. This can lead to some significant flaws and inconsistencies in our beliefs.
