The Redundancy Effect

If you are part of an organization that does lots of briefing, then you have likely had a boss who can’t stand it when the briefer reads verbatim the text that’s on a slide.

“Thanks, I can read.”

This is a common pet peeve. Anyone can read text from a slide. People start to wonder, is the text simply there as a crutch for the briefer?

If you’ve been around long enough, you may have come across a briefer or a boss who takes this one step beyond and states that actually, reading the text from the slide helps solidify the information – because it is being read and heard at the same time.

Strong opinions abound on the topic.

If you actually care, there is research into this. Out of it comes something called “the redundancy effect.”

Basically, it has been determined that reading the text on a slide verbatim does not assist in information retention as it tends to overload the short-term memory of the recipient.

Better, is a mixed approach, where the briefer augments text with narrative.

Better still is to reduce the use of text on the slides altogether and instead use images, charts, or data to augment the narrative of the briefer.

What’s your opinion? I know you have one.
