“We have an illusion of understanding. We think we understand the past, which means we're probably overconfident about our ability to predict the future. What we do not know is how much of our understanding depends on an explanation that we construct on the spot.”

Daniel Kahneman
Thinking, Fast and Slow (2011), Farrar, Straus and Giroux, Part I-II
Commentary
Kahneman identifies 'the illusion of understanding' as a systematic bias: we construct post-hoc narratives explaining the past, then treat these narratives as evidence of understanding. This false confidence extends to future prediction.
This is humbling: our sense of comprehending complex phenomena is partly illusory. We mistake narrative coherence for genuine understanding. This applies to history (why did the 2008 crash happen?), psychology (why did he behave that way?), and politics (why did the election go this way?). The narrative seems obvious—but only in hindsight.
