There May Be A Good Reason You Don't Understand Something

"The next time you hear something you don't understand, ask for clarification. You don't have to be apologetic about it, and the situation doesn't have to be confrontational. Those with science and facts and evidence on their side will be happy to explain what they mean. If the speaker cannot explain what he is talking about in plain language--or without resorting to other, even less clear terms and concepts--that's a warning sign that there's confusion on both ends of the line."
