Memory is always biased. And memory is something very organic, changing, breathing, living. It is far from a static piece of information, stored away in some folder of your brain. Yet many people think that’s exactly what it is.
In fact, the more you try to remember something, the more this memory might change from how things really were. With every recollection, you are more and more convinced that what you could barely remember at first really happened the way you remember. Your memories become your past, your life.
