Yesterday I wrote about how our speech conveys information in the direct meaning of what we say and also conveys additional information about us as a person. Our messages include the specific thing we said, and also something about how we are the type of person who knows about or cares about the thing we just communicated. This second layer of communication is very important, and is often more important than the information we actually express, even though we likely never acknowledge it.
As an example, Kevin Simler and Robin Hanson write the following in The Elephant in the Brain, “When you’re interviewing someone for a job, for example, you aren’t trying to learn new domain knowledge from the job applicant, but you might discuss a topic in order to gauge the applicant as a potential coworker. You want to know whether the applicant is sharp or dull, plugged-in or out of the loop. You want to know the size and utility of the applicant’s backpack.”
This example is really clear and we can see that the things being communicated are less important than the behind the scenes things that the communication tells us about the person. Have they been in situations that demand creativity, were they able to navigate those situations well, and can they now look back and clearly express what they learned from those situations? These questions are hard to ask directly, but the communication from the interviewee will give us answers to these questions whether they are directly asked or not.
As an example from my personal life, the other week I drew a river on a coworker’s whiteboard because I learned some really fascinating information about erosion and deposition within rivers from the Don’t Panic Geocast. The information I shared about rivers is not going to help either of us in our jobs or life in any meaningful way, but I found it interesting and wanted to share. What I was really conveying, however, was that I am the type of person who gets excited about science and fun geological processes. I was telling her, “hey, I’m the kind of person who picks up interesting but obscure information from across the world and can remember it.” If I just walked around saying that I would probably annoy everyone (not to say drawing rivers on other peoples whiteboards doesn’t) but at least in this way I can show my interests in the world and share a little bit about myself in a less obnoxious and intrusive manner.
We all do things like this at times in our lives. We are not conscious of it, because being conscious of it doesn’t actually help us be much better in conversations and social situations. Our brains continuously monitor, adjust, and respond to social situations, and we are able to send a lot of messages without either ourselves or the people we talk to actively noticing what we are doing during these conversations.
