If listening to someone talk on a cellphone seems incredibly distracting, there’s a reason for it. Researchers say the mind automatically tries to fill in missing information. So when you hear only half of a conversation, your mind tries to figure out what’s being said on the other end.
One study showed that people can tune-out a full-blown conversation, but have trouble tuning out a one-sided cellphone conversation.
So it’s not cellphones that are the problem, but our response to them. God designed us to be annoyed by cellphones.
