Even if you can't recall things unbidden, recognizing that something fits with your "sense of history" or not is useful.

Yes, but it's the standard school approach of "throw a lot of everything at the wall, something will stick". It doesn't look efficient or effective. I can see some sense in it during the middle/high school years because you're basically training kids to deal the overwhelming amounts of information (e.g. by forcing them to figure out what's important and what's not) -- however adult self-education should be able to do a lot better.
