We see that a lot in bad PowerPoint presentations. The presenter clutters up his slides with all those animations and cheesy clip arts on top of the 10 bullet points.
All these special effects do nothing but make the audience dizzy. They distract the audience from the message. The audience sit there wondering how the next batch of bullet points are going to appear. Are they going to fly in from the left? Or from the right? Or are they just going to dissolve first and then explode? Which bells are going to ring and which whistle will be blown? It is all utter nonsense.
Listen to Napoleon! Keep it simple and don’t try to be clever.
