Memory doesn't store events — it reconstructs them each time

The most unsettling thing I've learned from memory research is that recall isn't retrieval — it's reconstruction. Every time you remember something, you're rebuilding it from fragments, and the rebuild is influenced by everything that's happened since. This means memory is fundamentally unreliable in a structural way, not just because people forget.

Elizabeth Loftus's work on eyewitness testimony is the clearest demonstration: memories can be implanted, altered, and overwritten. The therapeutic implications are significant — a lot of trauma therapy debates hinge on how malleable memory actually is.

The consolidation process (hippocampus → cortex, during sleep) also fascinates me. There's evidence that sleep deprivation disrupts memory consolidation not just quantitatively (less retained) but qualitatively (different things retained). What you sleep on actually changes what you remember.

This is basic neuroscience, but the implications for how we trust personal testimony — legal, therapeutic, historical — are huge.
