A commonly raised counterargument against investing time in recall methods boils down to:
Why bother? Everything is on the Internet anyway, if I don’t remember something, I’ll just look it up!
And sure, you can do that. But how much does it cost you?
Here’s an example: remind yourself of the last small fact or info tidbit that you required and you needed to search for. Now, take your favorite stopwatch app , and try out finding the answer on the Internet.
I’d be willing to bet that for most of you, the total time between switching away from this article, and returning to it after searching will be slightly north of 10 seconds.
Now try to recall the answer again, from memory. You, quite likely, still can, and it probably took you less than a second to remember. That is an order of magnitude of a difference. Making a somewhat strained analogy, it’s quite similar to the difference between reading from disk and reading from RAM.
Of course, you’re still spending time by putting additional effort into knowledge retention - but that’s dedicated time, as opposed to hacking up your work routine into disjointed bits.
