Still, if we rely solely on e-mail at work, the absence of a channel for the brain’s emotional circuitry carries risks. In an article to be published next year in the Academy of Management Review, Kristin Byron, an assistant professor of management at Syracuse University’s Whitman School of Management, finds that e-mail generally increases the likelihood of conflict and miscommunication.

One reason for this is that we tend to misinterpret positive e-mail messages as more neutral, and neutral ones as more negative, than the sender intended. Even jokes are rated as less funny by recipients than by senders.

We fail to realize this largely because of egocentricity, according to a 2005 article in the Journal of Personality and Social Psychology. Sitting alone in a cubicle or basement writing e-mail, the sender internally “hears” emotional overtones, though none of these cues will be sensed by the recipient.

When we talk, my brain’s social radar picks up that hint of stridency in your voice and automatically lowers my own tone of exasperation, all in the service of working things out. But when we send e-mail, there’s little to nothing by way of emotional valence to pick up. E-mail lacks those channels for the implicit meta-messages that, in a conversation, provide its positive or negative spin.

On the upside, the familiarity that develops between sender and receiver can help to reduce these problems, according to findings by Joseph Walther, a professor of communication and telecommunication at Michigan State University. People who know each other well, it turns out, are less likely to have these misunderstandings online.

These quirks of cyberpsychology are familiar to Clay Shirky, an adjunct professor in New York University’s interactive telecommunications program. His expertise is social computing — software programs through which multiple users interact, ranging from Facebook to Listservs and chat rooms to e-mail. I asked Professor Shirky what all of this might imply for the multitudes of people who work with others by e-mail.
