I have been forming in my mind a series of essays called “Everything I Ever Needed to Know, I learned in Freshman Chemistry”. As I was working on my PhD, I taught freshman chemistry every semester. I truly enjoyed the teaching but also began to see that virtually every theory you learn in that survey course has an element (pun intended) broadly applicable to life. They don’t call it a Doctorate in Philosophy for nothing. From the Laws of Thermodynamics through Quantum Mechanics, there is always something important we can learn about life if we think about that theory in a broader context.
Today, I want to share one piece of advice about communication that I often gave to mentees (still do, in fact). It is related to the concept of the half-life of a radioactive element. Really. Let me explain. All radioactive elements decay over time, meaning they release subatomic particles and energy and become a more stable element. If you control this process, you can use that released energy to generate electricity. If you choose not to control the process, you can level cities in seconds. The graph that accompanies this essay demonstrates how this process can be viewed: the amount of the element remaining over a period of time drops exponentially; how fast this happens–the rate constant–is characteristic of that element. The time that it takes for half of the starting quantity of the element to decay is called its half-life. This concept is very useful, actually, in thinking about human interaction. I call this law the “Half Life of Effective Communication”.
When I first formulated this theory, there were limited means of communicating with someone. You could meet face-to-face, of course. You could talk on the telephone or leave voice messages. You could send letters, emails, faxes. That was about it. Texting came later, as did video conferences and now virtual and augmented reality. I began to realize that it was those face-to-face meetings that drove the quality of the relationship between individuals and my theory took shape: the effectiveness of communication via telephone, email, etc. decays exponentially since the last time you met with that person face-to-face. Additionally, the rate constant—or how fast that effectiveness decays—is a function of the relationship depth between the two individuals. If I’ve known you for a long time or if we worked next door to each other for a while, then one face-to-face visit will mean fun phone calls and preferential email attention for quite some time. If I’ve never met you or barely know you or it’s been ages since I saw you, then don’t expect preferential response. You are just less on my radar. While I admit to being very face-to-face oriented, I have found that most people are like to this at least to a degree.
Here is one way this plays out for me and this requires a bit of a confession: I really, really hate talking on the phone. I hate calling people I don’t know. I hate calling people I do know. I hate the phone. Whenever I want to be a really good partner to Trish, I volunteer to call and order the pizza. I’m still trying to convince her that is an effort worth recognizing. If you get a phone call from me, know that I’ve had to work up a certain amount of courage and/or overcome a significant amount of “eh” to dial you. If I actually answer the phone when you call me, consider it a small miracle (unless we’ve arranged a time for a chat and I’ve had a chance to prepare myself emotionally). I just hate talking on the phone. But if I recently saw you, I still have warm fuzzies from that personal interaction. Picking up the phone feels like continuing that recent face-to-face. It’s easy.
When you think about it, this theory makes sense. We humans have at least five senses (many consider intuition a sixth sense and who knows what else our bodies may be doing that we don’t yet know about). However, in phone calls we are using only one of those senses—hearing. You have the advantage of hearing tone, but you get no body language. In the written word, which we have become increasingly reliant on, we are using only sight in the form of reading. Not only are you not getting body language, you are not even getting tone (no matter how many emoticons someone uses). And we wonder why there is so much miscommunication! In person, we use sight, hearing, smell, touch, maybe even taste as an adjunct to smell. And our intuition is in overdrive, pulling on data from these senses and more. Relationships are built on all these data. In fact, they require all this information to get a holistic picture.
What happens if you are only using sight (in the form of reading) and maybe sound? Your brain fills in the gaps with assumptions. And you all certainly know how I feel about assumptions! How many times have you begun a relationship with a colleague by phone or email and when you finally meet them they are totally different from what you had pictured in your mind? Or a long distance working relationship seems rocky but YOU HAVE NEVER EVEN MET? There IS no relationship yet. How many times have you tried conflict resolution by email? Did that ever work for you? This phenomenon is even worse in our personal life, either on-line dating or social media, when people purposely try to show you only a small part of who they really are.
When video conferencing first came out, it was marketed as a way for companies to save money on travel since it would be “just like being there”. Except that it isn’t, even while increases in bandwidth have smoothed out early jerky movements. I worry that virtual and augmented reality are being touted anew as substitutes for being there IRL (in real life). We rely so much on social media for connection, but even Facebook is most effective with those with whom you have a deep personal relationship. There truly IS no substitute for IRL for honest relationship building. These other tools are all wonderful for extending the effectiveness of getting together face-to-face, but they can’t replace it.
I remember a commercial many years ago for some airline. The Big Boss had called his subordinates into a conference room and talked about how doing business had changed. They were doing so much more by phone and email and less in front of their customers face-to-face. In fact, he had recently gotten berated by an old friend and longtime customer for that lack of attention. He then tossed airline tickets on the table to each person, sending each out to see a key client. He held up his own ticket—one to go visit that old friend. Corny and self-serving to be sure—but with a big dose of truth. We MUST get face-to-face to build and maintain relationships. Don’t shy away from calls, emails, texts, video conferences, VR/AR–but remember the Law of The Half Life of Effective Communication.
