Mining Enron’s E-Mail

In our recent podcast called “The Dilbert Index,” we explored the idea of workplace morale. A recent study by Eric Gilbert, “Phrases That Signal Workplace Hierarchy,” provides an interesting window into who says what within firms, and why. From the abstract:

Hierarchy fundamentally shapes how we act at work. In this paper, we explore the relationship between the words people write in workplace email and the rank of the email’s recipient. Using the Enron corpus as a dataset, we perform a close study of the words and phrases people send to those above them in the corporate hierarchy versus those at the same level or lower. We find that certain words and phrases are strong predictors. For example, “thought you would” strongly suggests that the recipient outranks the sender, while “let’s discuss” implies the opposite. We also find that the phrases people write to their bosses do not demonstrate cognitive processes as often as the ones they write to others. We conclude this paper by interpreting our results and announcing the release of the predictive phrases as a public dataset, perhaps enabling a new class of status-aware applications.

The usage of “weekend” in a work email, for example, is likely to be sent to a superior. This is also true for the words “attach,” “that night,” “tiger” and “shit.”  Here are the top five in each group – upward means the recipients of the email outrank the sender, and downward the opposite:

 Top 5 Upward Predictors

  • the ability to
  • I took
  • are available
  • kitchen
  • thought you would

Top 5 Downward Predictors

  • have you been
  • you gave
  • we are in
  • title
  • need in

Keep in mind these findings are from the body of Enron e-mails, which may or may not be remotely typical. Gilbert notes: “the models build on data from a profoundly dishonest company which ultimately fell apart. At the same time, the Enron email corpus is without parallel in the research community. Nowhere else can you find such a rich, complex and naturally occurring email dataset.” 

And, while Gilbert doesn’t comment on what e-mail language says about employee morale per se, it’s not hard to imagine that a similar study could try to do so. If you were authoring that study — and perhaps you are — what do you suspect you might find as indicators of low, or high, morale?

    Downward indicator of high morale: thank you.

    I think it is interesting to try to ferret out whether the usage rates are indicators of deference and rank, or are predictors of success.

    For instance, would inserting “tiger” into more emails result in vaulting up the corporate chain? Perhaps not, but maybe a person bold enough to do so would vault anyways.

      Dear Boss:

      I took your advice attached that s–t to the project proposal for you, Tiger! I thought you would like that.

      Now I’m off to the kitchen to see if any leftovers are available. I hope this weekend is nothing similar to that night when I didn’t even have the ability to see straight when I left the bar!

      See ya monday, Tiger!

    Surely “kitchen” refers to Louise Kitchen, former Americas COO?

    Was this specific to Enron or is it common for people in corporate environments to discuss excrement and large felines with their bosses?

    Here’s one I’m wondering about – not morale exactly, but is it possible to predict layoffs or divestitures by tracking employee use of LinkedIn? Purely anecdotally, it seems to me that when employees have a sense that the company is ‘unhealthy’ and they suspect impending layoffs, that people spend more time updating their LinkedIn profiles, making new contacts, etc. If statistically valid, this could be a great tool for picking stocks.
