There was a good discussion on LW about Arthur Chu's performance on Jeopardy LINK - especially how he took advantage of regular patterns underlying question selection and "random" events to try and maximise his winnings.
The comment thread on that discussion also mentions other "rationalist" practices by other contestants.
Note that Arthur does not consider himself a rationalist, and hates LW.
This thread is for asking any questions that might seem obvious, tangential, silly or what-have-you. Don't be shy, everyone has holes in their knowledge, though the fewer and the smaller we can make them, the better.
Please be respectful of other people's admitting ignorance and don't mock them for it, as they're doing a noble thing.
To any future monthly posters of SQ threads, please remember to add the "stupid_questions" tag.
