Obnubilating abaft applied vernacular

We have all been in a meeting or listened to a talk where the presenter waffles convolutedly on a topic. You only end up understanding around ten percent of what has been spoken. If you find yourself listening to something science or medicine related, you may feel like you’re listening to another language entirely. But like any language, you can begin to understand the jargon, and begin to understand the substance of discussion. Sometimes this jargon is the key to a topic, where a single word may contain an encyclopaedia of conceptual information. And sometimes this jargon is complete and utter rubbish. It can be nonsensical word junk designed to fill your ears and mind with the sense you’ve listened to something meaningful. 

Confucius say: Why waste time say lot word when few word do trick.

As you gain greater understanding of the complexities of language on a topic, you begin to make improved judgments on whether the speaker is an expert or a pretender. Try and truly understand what they are saying, instead of the surface level appreciation that you get because they possess more knowledge in a particular area than you. We must overcome our cognitive bias of automatically giving power to those who speak on topics we are yet to understand.  Humans are always looking to conserve energy. It's much easier to repeat something as fact if you don't understand it, than look up all the relevant topic information and make your own judgement. This has caused the increased rate of spread of both misinformation and information. 

Who should the train of information run over?

As always, we must be mindful of our audience. We must remember the practical applications of our speech and use common sense. If a simple explanation is expected, then a simple explanation is required. If a technical audience demands intricate detail and nuance, then you should provide them with high-tech blueprints a wordsmith would be proud of. There is no point stroking your ego in a talk for your own sake. Clarity of information is the same as freedom of information. Although an encyclopaedia may contain a lot of information, if it is hidden behind complicated cryptography it is useless. And always beware the expert who speaks in paragraphs but rarely says a word.
