You made it clear in another reply you weren't including work, which for me is where the bulk of disruptive interruptions come from. Some days it may only be a couple, but it can also easily be dozens. On a personal level, I don't consider "Netflix time" interrupting anything -- it's like the lowest priority thing I ever do, and I'd happily answer a call from a friend or family member. I and most of my friends have kids, so we rarely spontaneously call each other: it's usually preceded by a text along the lines of "You around?". I'm not sure what would happen with only phone; probably just less communication overall. Today I'll sometimes get (or send) a text in the middle of the work day, but I'm not sure that would be replaced by a phone call -- it would either happen outside work hours or not at all. Excluding group chats is also not really fair: for example a group chat I'm in now has been about arranging a get-together soon, and that would likely involve several phone calls to make it happen and figure out a time that works for most people. There's also some correspondence that happens over email today that you'd have to consider. For example, if you're moving (selling / buying houses) there's a whole ton of things with real estate agents, lawyers, bank and insurance that have to happen. If your lawyer calls to confirm a couple details, you either interrupt what you're doing or pay them extra as they can't finish their work and will have to pick it back up later (your return call is just as interrupting to them!).
