I’d say I’m hovering around the 60% mark.
I don’t answer calls from numbers I don’t recognise, unless it identifies someone I’m expecting a call from with the “maybe” thing. I don’t use my phone for work (often). I don’t call people to catch up, I’d rather IM. My mother or my best friend call and I ignore them more often than I probably should.
But really I just don’t like talking on the phone that much.
This is part of why I straight up do not trust most “reliable polls”, because tons of them are still conducted via phone, and in the era of constant spam and caller ID, most people younger than boomers just don’t answer unknown numbers, and also don’t even have, and in fact have never paid for, a landline. Not to mention, I still have a west coast area code, and I live on the east coast, and most of my friends have area codes from wherever they grew up, not where they live now, so targeting by area code is often nonsense.
