As Quartz reports, The pen is not only mightier than the sword, but in some cases also mightier than the keyboard.
It may well be that the physicality of shaping letters cements concepts in the mind. For example, to type the word “typing,” I made the same motion on the keyboard six times, choosing which letter to type but not forming them. But if I were to write the same thing by hand, I’d have to shape six different letters and put them together. That takes more effort and seems to both demand more of the brain and leave a deeper imprint on the mind than typing. That imprint appears to be critical when learning new things.
Plus, there’s the priceless benefit of limiting distraction. Technology can be a trap. The simple act of shutting your laptop and putting pen to paper can help you to improve focus.
