My phone is set to Do Not Disturb by default. Only 5 numbers can reach me direct to ring and that is immediate family only. I never answer calls from unsaved numbers. If they really need to reach me they can leave a voicemail.

When you answer a call your brain kinda loses its ability to step back and think. Almost like the same trick that those people who ask for directions and steal your watch do.

Security is not the main reason I do this but it has been nice knowing I can't be reached directly by scammers and hackers.

I stopped answering unknown numbers because everything that's important comes via email anyway. But a friend of mine has a job that requires them to answer calls from weird numbers, so it's tough.

Doesn't any legit caller always leave a message? That way, you can think through the security issue before responding.
