How your brain keeps memories tidy

How do our brains keep our memories tidy?  "An experiment conducted by Nicholas Turk-Browne, an associate professor of psychology at Princeton, and his colleagues found that the human brain uses memories to make predictions about what it expects to find in familiar contexts. When those subconscious predictions are shown to be wrong, the related memories are weakened and are more likely to be forgotten."

I wonder if Marie Kondo approves?
