An Overfull Slide With A Long Title Nobody Is Going ToRead In Time Anyway

Well, see, overfull slides are a distraction from the talk itself, and do not helpANYONE. The time you need to read this slide you cannot use to listen tothe speaker, who is going to tell you something else (because, well, the otherthings are on the slide, aren’t they?) So, you miss stuff, and maybeimportant stuff. On the other hand, if you listen to the speaker, you missthe stuff from the slides, which will not be repeated, because . . . I think youget the point.To maximize confusion, do not use overlays, because this would actually helpreading the slide. Just put everything on one slide, talk while the slide is onscreen (but not too long!) and then go on. Nobody will ask questions aboutyour talk then, that’s guaranteed.

Using Itemize to Decrease the Auditorium’s Attention

I If you have to use itemize, make sure it does fit on the screen

I Better make slides with too few words than with too many.I Don’t make long entries in the itemize environment, this will just

confuse anybody who wants to read what you have on your slide.Anyway, presentations should not be summaries of your papers, shouldthey? Well, then! And of course, long sentences on your slides arealways a bad idea.

I Don’t use nested itemize environments

I They won’t help!

I And won’t clarify stuffI Important stuff

I Which may be relevant!I But nobody is listening anyway!

I But instead is checking emails . . .I Or is surfing the webI Or is doing other (not so important) stuff

Because they tend to be rather thin
