Paying attention to data and predictions teaches the lesson to suspect models
By paying close attention to the new observations and comparing them to past interpretations, we are able to gain a better appreciation for our ignorance. Our models may be imperfect. There may be previously unknown variables that can have major consequences. We need to pay attention in order to observe the failure of new information confirming old expectations. Doing so teaches us respect for our ignorance. In particular, such experiences justify fears and doubts for future decisions.
