> Professonal quizzers can absorb huge amounts of information but typically don't use flashcards.
Professional quizzers almost all use flashcards. Jeopardy! people definitely do. The range of questions that you can ask in a general knowledge quiz are surprisingly limited. You're not going beyond a surface-level overview on anything. Do a ton of general knowledge flashcards for a year and you'll annihilate people at pub quizzes.
I suppose you could just read encyclopedias over and over again, and books of lists.
Ken Jennings doesn't! I am speculating though so I'll defer to your knowledge here. I was trying to say, for some people it comes naturally. I doubt the majority of quizzers are doing 300k reviews a year.
Reminds me of that guy who "mastered the NYT Crossword" by flashcarding questions/clues. I also learned to do the Saturday consistently - just by doing the crossword every day for a while. You don't always need flashcards.
