The most common mistake when giving a presentation
By far the most common mistake when people give presentations: writing out full sentences on a slide and reading them out loud to the audience. This is considered to be a mistake because it does not take into account the ‘redundancy effect’.
The redundancy effect is a very straightforward principle that says that if someone READS a message and HEARS the message at the same time, the brain shuts out (no retention). Therefore this ‘technique’ of presenting is extremely ineffective.
Although it is not recommended to use too much text (or text at all for that matter) in slides, if you do, NEVER write out full sentences when using bullet points. Use a couple of keywords you can use to construct a full sentence when presenting.
