Somehow people seem to think it makes them seem smarter when they speak in jargon, acronyms etc. They feel if they use terms that others don’t understand, it will demonstrate their intelligence and expertise in the subject matter.
Smart people know if they say something in a way that others don’t understand, it’s not the others who are lacking but rather the ones who communicated poorly.
If you want to seem smart, communicate in a way that others can understand. Speak simply.
Have a great day!
