Let’s start with the hard science. It has been well and repeatedly proven that people who take notes by hand, rather than on a device, understand the material better and retain it longer. Likewise, children who learn to read through writing by hand remember and recognize letters more accurately. Whereas, what we type — to mangle a metaphor — goes in one ear and out of the other.
This research has actually been around for a while, and it is undergoing a weird disjunction: The more often the experiments are repeated and validated, the more people ignore them. I believe the research is ignored because it implies an entirely new paradigm, one that asserts we see with our hands as much as our eyes — or more accurately, we remember with our bodies as much as our brains.
Writing by hand is an embodied act; our muscles remember the gestures that form the shapes. Writing by keyboard, on the other hand, disengages our motor memory because every key is the same, and what we see on the screen bears no relationship to what we are doing with our hands.
But the hard science actually goes a lot further — so far, in fact, that researchers hesitate to trumpet their discoveries because they seem almost miraculous. I’ll quote myself here, from a passage in my most recent book, By Hand:
“An article in JMIR Mental Health, summarizing previous studies (which now number in the thousands), found [that journaling] had ‘clinical benefits tied to expressive writing in patients with autoimmune and inflammatory conditions such as arthritic conditions, lupus, and asthma; fibromyalgia; irritable bowel syndrome; and HIV or AIDS. In addition, expressive writing has been found to have beneficial effects on blood pressure and on several health-relevant outcomes following the experience of a heart attack, such as reduced number of medical appointments and prescription medications, increased self-care behaviors, improved cardiac symptoms, and improved health-related quality of life.
“‘Expressive writing has also been associated with small, but consistent, improvements to well-being among diverse cancer groups — especially breast, renal, and prostate cancer patients. Finally, a relatively small study of…people diagnosed with major depressive disorder found that those writing about their deepest thoughts and feelings related to emotional events had significant reductions in depression immediately after writing and over one month thereafter.’”
I myself found this hard to believe until I experienced the health benefits of writing by hand, as well as the moments of self-revelation.
