It makes sense to use a bold font to highlight information. Used sparingly and logically, bolding focuses the reader’s attention on a particular part of a message.
But too much bold text, which I am illustrating here, makes readers dizzy.
The other day I read a research report with bold text sprinkled everywhere. On one page, 25 separate instances of bolding fought for the reader’s attention. It looked just like this entry. I couldn’t fix my attention anywhere.
Have I made the point?
