In The Elephant in the Brain authors Kevin Simler and Robin Hanson investigate human communication and ask why we are so quick to speak, communicate, and share information we have acquired, even if we acquired that information at great personal costs. Humans communicate a lot, and we generally like to be the one talking and expressing something about ourselves and our experiences. The problem however, is that it would make more sense for us to do all the listening, and only talk when absolutely necessary or when we were getting a reward.
If I spend a lot of time reading a book and learning something interesting and useful, I should desire a reward for the cost of learning the information I know. Before I write a blog post about interesting information, pontificate at the water cooler, or tell my family something I find fascinating, I should ask to be compensated. Instead, what we usually see, is that we can’t wait to tell people about the interesting thing we have learned. We expend a lot of effort in learning new information, and then we give that information away as quick as we can to anyone.
We also don’t do a great job listening. Rather than spending a lot of time absorbing what the other is saying, we prepare ourselves for what we are going to say next, missing the entire thing that is actually being said as we mentally prepare for our turn to talk. From an economic standpoint, this does not make sense.
“We aren’t lazy, greedy listeners. Instead we’re both intensely curious and happy to share the fruits of our curiosity with others.” Write Simler and Hanson, “In order to explain why we speak, then, we have to find some benefit large enough to offset the cost of acquiring information and devaluing it by sharing. If speakers are giving away little informational ‘gifts’ in every conversation, what are they getting in return?”
I’ll explore this idea a little more in coming posts, but the authors argue that conversation is not really (at least not solely or even primarily) about conveying information. We do a lot of group and alliance signaling in our conversation. We show how creative and insightful we are. We demonstrate to others that we are willing to go learn new and useful information that can benefit the whole group and we show how altruistic we are by sharing this information which we acquired at a great cost. These are important but often unrecognized or unacknowledged parts of our communication. When we speak and when we share information, we are doing much more than just telling people what is inside our head.
