Unreliable source but interesting concept. I don't get the same net effect from taking notes on a computer, either. I wish I understood how to take/capture notes digitally in a way that is as useful as paper notes.

A lost note written on paper is much easier to recall than a "lost" or difficult to locate digital note typed up with some reminder.

I think it has to do with the uniqueness of each handwritten note - whether in the margins of a book or on sheets of paper, each note is unique and has visual, sound, and even textural differences.

Picking up an old notebook with a coffee ring on one of the pages brings back "the day" and the moment of taking those notes much differently than opening a file last modified last week. As much as I love digitizing as much as possible, my brain seems better suited to paper.
