PowerPoint Tyranny -- Dickeson

They're included as presentations on the Internet sites and in e-mails. We're rapidly becoming a nation, in fact, a world, of PP heads.

Well, what's wrong with the PowerPoints? The principle fault, says Tufte, is that they tend to constrain thought to "bullet points." PowerPoint becomes a straitjacket for the mind, condensing thought to a linear outline of what you can say and what the audience can think. The real world doesn't work that way. Tufte traces much of the Challenger and Columbia space catastrophes to failed PowerPoint reasoning expressed by NASA and engineers of suppliers.
