Jargon is that beguiling insider language that makes you and your cohorts feel like members of a secret society. Jargon is a short cut that communicates a concept in a few choice words. It's also natural to rattle off jargon while you're speaking. So why not pepper your speeches and presentations with jargon?
Why not, indeed?
1) When you use fresh language to explain or describe the concept convered by jargon, the brains in your audience pay attention. Audiences are at the mercy of their human brains that tune out anything that is too familiar. Brain science has proved that once a thought, picture, or concept is stored in the filing cabinet of your brain, each time you encounter that idea again it makes less and less of an impression.
2) Sticking to jargon restricts your own mental accuity and inventiveness too. Speaking and presenting should be oppportunities to expand your own thinking, not keep it in a rut. When you dig into your deeper vocabulary, you get energized and you transmit that energy to your listeners.
3) The combination of an attentive audience and a deeper thinking speaker is the only way to break new ground. Think about the most successful companies today--they are lead by people who saw what the crowd did not see and then took action. When you break out of the confines of jargon, who knows where and how far you'll find you can go?
Never default to jargon when you're speaking. The English language has upwards of 600,000 words in it. Use a few more words each day than the day before and soon you'll be succeeding by the power of the language.
