We are really saved from ourselves by our curiosity. If you think you understand something, it's time to learn more about it. Because the mind is an associative machine, and it takes whatever you've learned so far and constructs a story that make sense. Whether or not you have really dug deep and learned what you need to know. In trying to help you understand the past so you can prepare for the future, the 'fast-thinking' mind seeks coherence NOT truth. Truth comes from the slow, hard process of thinking more deeply and questioning what you know. For me, the easiest way is to just get curious about it.
Thinking, Fast and Slow by Dan Kahneman, 2011
The world makes much less sense than you think. The coherence comes mostly from the way your mind works.
