One of the most challenging pub quiz trivia questions is: What is the largest desert in the world? The answer is Antarctica, which is considered a desert because it has very little liquid water or air humidity. The reason this trivia question is so difficult is that most people will wrongly assume deserts need to be hot and never even consider a location like Antarctica.
Respondents to a trivia question survey indicated they had the least confidence in their answers on sports or political trivia. Questions like who scored a pivotal goal in a specific game or who a second-tier politician like a state governor is make for difficult trivia questions.
Here are some examples of more questions from the survey for which people tend to give an obvious, but wrong, answer: What animal are the Canary Islands named after? Answer: dogs. What is Paul McCartney's middle name? Answer: Paul (his full name is James Paul McCartney). How many man-made objects can be seen from space? Answer: none. (The Great Wall of China, which many people erroneously think can be seen from space, is far too thin.)
Despite most survey respondents listing entertainment as their best subject, most get this one wrong: In the TV series Dallas, who shot J.R. Ewing? Answer: Kristen Shepherd (not Sue Ellen Ewing).
