Your brain doesn't just store memories — it stores predictions. Every time you recall something, you're not replaying a recording; you're running a simulation of what probably happened, shaped by everything you've believed since. This is the unsettling discovery at the heart of neuroscientist Daniela Schacter's work on 'memory errors' — but the philosopher Alfred North Whitehead saw something structurally similar a century earlier: reality itself is not a collection of fixed facts but a process of 'prehension,' where every moment inherits and reinterprets what came before. Together, they suggest something uncomfortable about how you plan your week. The mental model you call 'what I know about my work' or 'what that conversation meant' is not a library — it's an active argument your brain is constantly winning against the past. The practical move: treat your own confident memories of how a project or relationship unfolded with a scientist's skepticism. Not paralysis, just a small gap — the same gap you'd give a witness account.

What is one story you tell repeatedly — about a failure, a turning point, or a person — that you have never once fact-checked against another person who was there?
