“Memory isn't about playing back a perfect recording of the past. It's highly reconstructive, piecing together a higher-fidelity picture based on fragments and guesswork.

He didn't. Or whether the Berenstein Bears were actually once the Berenstein Bears. My take on this is that brain psychology and memory are messy things. Memory isn't about playing back a perfect recording of the past. It's highly reconstructive, piecing together a higher fidelity picture based on fragments and guesswork.
