With today’s easy access to information it’s common that we no longer memorize “content”, but instead we make mental notes only about where to find it. We dog-ear book pages, underline paragraphs, bookmark websites, save videos. Etc.
If there’s something we need to be reminded of we know where to look for it. This creates the problem of not committing information to memory. We feel like we no longer need to, that we only need to know where to get it. Our memory has become an index. It shows us where to find the knowledge, but never holds the knowledge itself.
