New evidence that bullet-points don’t work
October 7, 2009
At last, we have some scientifically rigorous evidence to show that slides full of bullet-points don’t work.
The research is the work of Chris Atherton, a cognitive psychologist. Chris recently delivered a presentation at the Technical Communication UK Conference and has put up her slides on slideshare. There’s been a tremendous amount of interest in them, but as they were designed to complement Chris’s talk – they only tell half the story.
In this post I’ll explain the findings of Chris’s research. I’ve written the post based on Chris’s slides and asked Chris to comment on various aspects. Chris has also reviewed this post to make sure I’ve got all the science right.

January 9, 2009
