"PowerPoint makes us stupid," Gen. James N. Mattis of the Marine Corps, the Joint Forces commander, said this month at a military conference in North Carolina. (He spoke without PowerPoint.) Brig. Gen. H. R. McMaster, who banned PowerPoint presentations when he led the successful effort to secure the northern Iraqi city of Tal Afar in 2005, followed up at the same conference by likening PowerPoint to an internal threat.
"It's dangerous because it can create the illusion of understanding and the illusion of control," General McMaster said in a telephone interview afterward. "Some problems in the world are not bullet-izable."
Commanders say that behind all the PowerPoint jokes are serious concerns that the program stifles discussion, critical thinking and thoughtful decision-making. Not least, it ties up junior officers -- referred to as PowerPoint Rangers -- in the daily preparation of slides, be it for a Joint Staff meeting in Washington or for a platoon leader's pre-mission combat briefing in a remote pocket of Afghanistan.
Senior officers say the program does come in handy when the goal is not imparting information, as in briefings for reporters.
The news media sessions often last 25 minutes, with 5 minutes left at the end for questions from anyone still awake. Those types of PowerPoint presentations, Dr. Hammes said, are known as "hypnotizing chickens."
