It's worth noting that they were speaking about their personal experience in that paragraph. So probably for them, the "how do you get to that conclusion" is "trial and error".

But I've noticed that many many many people report the same effect, that there's something about pen-and-paper writing that's more effective for thought-lubrication. I resisted for a long time, but now I too am a convert to this school of thought.

Similarly almost everyone notices the downside: it's easier to reorder, reorganize, cross-link, etc, those thoughts, in a text editor (to say nothing of more sophisticated software tools). Some people have systems for doing complicated things with paper that they say mitigates this downside, but I am not currently one of them.

I guess it's possible that your brain just doesn't have this pattern in it. (That is, the pattern of finding pen-and-paper more effective for getting the thoughts to flow.) I mean, for all I know, maybe the huge silent majority doesn't have this pattern.

In my personal experience, a helpful feature of pen and paper is that it is less effective than keyboards, it takes me more time and focus to write things down. Maybe this gives the rest of my brain more time to catch up and understand the things that I am writing.

Written text is also less efficient when it comes to searching. This forces me to organize my thoughts better because I know I won't be able to CTRL+F random keywords later.

Another benefit of text is search, especially across documents. Also great for spellchecking and rearranging phrases, sentences, paragraphs.

But writing enables arrows, lines, crossing-out, small-text notes, circling, variable pressure, colour, etc. Richer than ordering/indenting text. Also higher contrast.

I will go even further. The physical sensation of pen on paper ... including the texture and pressure you apply to key words, capitalization, underlines, etc ... all of it being fed back though your muscles into your brain and getting processed/stored/intertwined with those very ideas and thoughts you are putting on paper ... and the mental faculties you allocate to aligning the text against the margins, ensuring neat spacing, etc ... puts your brain in a zone better tuned to the task at hand IMO.

Some of it may be just ... overload your brain so it cannot think of anything else ..so you stay focussed for lack of choice.

I mostly came to this conclusion in math classes at uni. Handwriting my notes was far superior (in terms of knowledge retained) to using my laptop. My recall was excellent. You could argue that writing math is hard in a text editor (due to the required symbols) but I think it was deeper than that. Writing on paper requires more mental focus than smashing keys, it takes longer and that feels good when you're digesting abstract concepts.

I don't write code on paper for (probably) obvious reasons, and I tend to write essays in a text editor although I also enjoy the act of writing on paper in that situation.

Different people undoubtedly come to different conclusions on this.

Personally, I find while the computer provides powerful writing tools, it also provides powerful distractions.

Maybe you get notifications you just quickly want to check, that slack message from the boss could be urgent. Maybe you decide to just check you're using that obscure word right, or to research a detail for your writing and an hour you haven't written the number of pages you set as your goal. Or maybe sitting in your netflix-watching chair looking at your netflix-watching screen just doesn't put you in the right mindset.

My habit for college essays was to write scratch notes on paper, with lots of bullet points, and arrows for re-arranging text, to get the outline of the essay in place, but to actually put the real words together on the computer.

I remember my mother once doing the opposite: she wrote a long letter on the computer, so she could edit and re-write until she was happy with it, then printed it out and copied it by hand, for the personal touch of a hand-written letter (a peacemaking letter to a relative).
