The effects of pulling out a notepad and jotting notes are markedly different than pulling out a phone or tablet- especially in a conversation or meeting. IME a phone signals disengagement, while a notepad signals the opposite. When I pulled out my pad, I could see body language and word choices change almost immediately. If it was a positive or neutral conversation, people tended to show appreciation for my interest in what was being said. If it was a negative interaction, people started to be much more careful about what they were saying.
Now I carry an attaché case and use larger, more professional looking, notebooks. Even in the age of Zoom, I angle my camera to ensure it’s obvious I’m taking notes. Sure, it’s an extra step to digitize the important stuff, but I think it’s worth it.
