Anomalies:

"How you respond to anomalies is a good indicator of your open-mindedness. Anomalies are like a glitch in the matrix. You can identify these moments when you find something surprising, missing, or strange. Anomalies indicate the world doesn’t work the way you thought it did. These moments can be worth their weight in gold if you pay attention. Closed-minded people tend to ignore or gloss over anomalies. Open-minded people want to dive in and understand. Of course, diving in is hard as it may require you to discard your ideas and beliefs."
