PowerPoint Tyranny -- Dickeson
The outcomes of those flights might have been different had opinions been more clearly expressed than they were in bullet point outlines of linear thinking.
Tables and charts in PowerPoint can only show limited information because of the space available on a computer screen or in a computer printout. A more complete picture might have triggered additional thoughts. They represent a formal managerial style of hierarchy.
The outline format represents the speaker's reasoning. Real audience interaction, were it not constrained by the PowerPoint logic prepared by the speaker, might lead to an entirely different conclusion. The PowerPoint abbreviated form of reasoning is, therefore, a restraint on audience interaction. Hence the tendency to nod off in boredom or to reach a mistaken, or limited, view of a problem.
It's strange, but the PowerPoint outline style—linear reasoning format—makes no sense at all to the Japanese or other Asian peoples. In the Orient, supporting points loop around the main point without creating a linear argument, leaving the reader open to inference. Does this tell us something?
It's true, as Tufte and others point out, that we read printed materials much faster than we speak them. As a result, members of an audience will grasp written words on a PowerPoint screen at a much greater speed than a speaker can say them aloud. This explains why many bullet point presentations must delay revealing those points, waiting for the speaker to catch up, or trying to get ahead, of the group.
And then there's all that PPPhluff, as Tufte calls it. It starts with the colors and presentation style of "templates" that further constrain the space available for context. It includes the points flying in from left or right, above or below, in some kind of mysterious pattern of appearance and disappearance, or fading to different colors. There are even sound effects for emphasis. Anything, anything at all to keep the audience awake!
