Why Do Our Minds Cook the Past?

Our memories are not necessarily like a video recorder. Human memory doesn't have the hard drives based to video tape life in its entirety. Our brains play fast and loose with the footage. After all these edits, our memories are no longer accurate recordings of real life events. They're unconsciously spin doctored highlight reels. It's a bias that lee and her colleagues have referred to as rosy retrospection. But rosy retrospections aren't just memories we think back on passively. We also use them to predict what we will enjoy and won't enjoy in the future.
