One of the bigger issues with communicating science to the general public is how educators continue to overestimate the hoi polloi’s grasp of scientific vernacular; ie. they ignore or forget the fact that laypeople hear one thing but understand another, simply because the scientific meaning to those terms is foreign or unknown to them. We see it all the time, with perhaps the most notorious example being those who claim that “Evolution is just a theory!” (as if that were a dismissal of anything other than their own credibility on the matter).
To demonstrate just how prevalent this problem is, here’s a useful, if somewhat discomforting, chart:

Phil Plait has more. It’s really crucial for the experts to understand that most people don’t share their expertise and simply won’t understand what they mean to say unless they speak a language that John and Jane Doe can actually understand, even if this means simplification to the extreme at times. That’s the price of communication.
