Social interaction now-a-days is drastically different then it was seven years ago. The idea of e-interaction has basically altered social interaction forever. With the advent of websites designed with the intent of being a “Place where friends meet” (myspace.com) or “[Facebook is] a social utility that connects you with the people around you.” (obviously facebook.com) one cannot expect to ever have to leave the comfort of home again. Basically sites like these allow for their users to meet people and talk to each other in one of two ways, private (email) style messaging or publicly commenting (wall writing).
On page four he instantly comes to griping with that, “These costs arise from the cognitive style characteristic of the standard default PP presentation:….” Tufte then lists at least ten things that a normal PowerPoint presentation is either lacking or weakening its data content.
Tufte cites “foreshortening of evidence and thought” basically meaning that PP is weakening a presenter’s argument to begin with because its taking away from that which you are using to support your argument because of a limited data field and using fragments of ideas instead of the whole.
Another critical fault in PP, Tufte states, is its “hierarchal bullet list”. He says how for hundreds of years information has been conveyed without bullet style points, but PowerPoint only uses bulleted points. He then shows the reader, on page 18, a bulleted version of the Gettysburg Address and begs the question, What if
What also ties into that previous facet, is that there is no causality within PowerPoint. It’s impossible to follow the data presented in a PP, unless its in a graph (which even then is statistically lacking), because there is no linear relationship between one piece of information and the next.
The low-resolution style of PP is also problematic, claims Tufte. He uses a brilliant example of two pictures of the space shuttle
Tufte’s most brilliant point, for me, is the fact that PP wasn’t intended to bring information to people in the way that it is being used. PP was developed for business people to make presentations to develop powerful points for the products that they are selling. By using PP presenters often turn otherwise useful information into a sales pitch.
