And I wish that honesty extended to other realms of knowledge.
Imagine somebody saying, "I think I remember something that said the capital of Honduras was Guadalajara, right?" Sounds weird. It's way more natural (and true) to say "The capital of Honduras? Uh, I have no idea."
But that ^ is exactly what a lot of folks do when faced with conversation on science topics they don't know about, or history, or any number of fields: blurt out half-remembered anecdotes in the hopes of landing on knowledge by coincidence.
People are terrified of the perceived embarrassment of admitting ignorance (read: inviting the opportunity to learn), and yet consistently commit to the assured embarrassment of not knowing what they're talking about.
Except when it comes to geography. That's something people are comfortable not knowing, comfortable saying so, and comfortable looking it up. As it ought to be.
