I apply the Getting Things Done methodology my personal task management. Additionally, I employ the Zettelkasten method, as described by this: www.soenkeahrens.de/en/takesmartnotes
In case that you might be familiar with those methodologies, there is a mandatory temporary or previous stage of everything that I process that I do in paper. As such, I use pen and paper for capture and for meeting notes. Afterwards, I process those into the right places using digital tools for later review. I could not fathom capturing these snippets of information using digital tools. Pen and paper is simply faster and more convenient.
I work in IT, specifically managing projects and coordinating teams. They always give me weird looks when I wipe out my notebook and pen and start taking notes. I am unyielding in this matter. Additionally, I always prefer using a whiteboard when discussing something with other people, instead of using some kind of bloated online app. It is faster, and future-proof.
Also,
There is scientific evidence that taking quick notes with pen and paper has cognitive advantages over keyboard typing.
I would say that the biggest difference between taking notes in pen or keyboard is that, using pen and paper I’m able to synthesize and draw information in a more free-form and unstructured manner. While taking notes with a keyboard feels more like I’m an stenographer, merely transcribing word by word what is being said.
