4. ‘technology’, as the computer
scientist Bran Ferren memorably
defined it, is ‘stuff that doesn’t
work yet.’ We no longer think of
chairs as technology, we just
think of them as chairs.

Part 1: How to make a bad
presentation
!Low-contrast text
!Distracting backgrounds
!44pt 32pt 24pt 18pt 12pt Small text
!Cheesy Animation that distracts from the
point
!paragraphs that go on and on in fonts that are hard to
read, animated in in such a way that you can't read the
whole thing right away but must wait for it to slowly
march in, and you are distracted trying to read it so you
don't pay attention to what the person is saying, even
though they are just going to read the paragraph to you
as you read it to yourself making the presenter redundant.

68. 3 kinds of information:
• your notes
• slides
• handout = paper
!
THESE ARE ALL
DIFFERENT
70. Presentations largely stand or fall on the
quality, relevance, and integrity of the
content. If your numbers are boring, then
you've got the wrong numbers. If your
words or images are not on point, making
them dance in color won't make them
relevant. Audience boredom is usually a
content failure, not a decoration failure.
71. At a minimum, a presentation format should
do no harm. Yet the PowerPoint style
routinely disrupts, dominates, and trivializes
content. Thus PowerPoint presentations too
often resemble a school play -very loud,
very slow, and very simple.
72. The practical conclusions are clear.
PowerPoint is a competent slide manager
and projector. But rather than
supplementing a presentation, it has
become a substitute for it. Such misuse
ignores the most important rule of speaking:
Respect your audience.
