For many years, I used to brag about how little sleep I needed. 5 or 6 hours was plenty; 7 was a luxury. I even once blogged about the benefits of resting as an alternative to sleeping. I’m not alone. Many (perhaps even most) of my colleagues / acquaintances have told stories about getting very little sleep…
In the climactic scene of the movie A Few Good Men, Lieutenant Kaffee (Tom Cruise) demands the truth from a testifying Colonel Jessup (Jack Nicholson).

Both have certainly fundamentally changed our lives and it is difficult to imagine living without either of them. But a case can be made that the telegraph was just as impactful. The telegraph, for…
I’ve been doing some spring cleaning and stumbled upon one of my favorite University textbooks: Tversky and Kahneman’s “Judgement Under Uncertainty”. This book taught me the basics of probability, a ridiculously useful skill which I’ve relied on far more frequently than I ever would have imagined. A better understanding of probability can help us overcome…
Many people complain that they get too many emails and there’s even a phenomenon called Inbox Zero. But do we really get that many emails? And do we really want fewer emails? In the book The Tyranny of Email, John Freeman claims the average office worker “sends and receives two hundred emails a day.” According…
I recently took part in an event which the organizers described as happening under the Chatham House Rule. After talking to many of the participants, I realized we were uncertain exactly what this meant. We assumed the rule implied confidentiality – but we disagreed on how much. Most of us were wrong.
