As the psycholinguist Herb Clark has pointed out, human communication is optimized for small numbers of people to talk together face-to-face in real time. The further we get from this ideal situation, the more opportunities there are for communication to go awry.
And, yet, so many of us work with people who we never see in person because they (or we) work remotely, are in different offices, or in different parts of the world. This can make communication challenging. This is particularly true when the situation or topic of conversation is going to create stress for you, the other person, or both of you.
When you are trying to explore topics with your colleagues that are emotionally or conceptually difficult, it’s good to get as close to the ideal situation as possible. Being able to interact in real time lets people interrupt a speaker if they get confused or have trouble following the conversation. This coordinated negotiation is a hallmark of effective communication.
