Just for fun - let's play a game.

How well can we, at Less Wrong, tell the difference between truth and fiction? Let's play a little game, which I once saw in a movie.
In this game, we each say five things about ourselves, four of which are true. We then try to guess which ones are true and which ones are lies. (Go ahead and use Google, if you like.) I'll start.
My five facts:
1) I have another LessWrong commenter's autograph.
2) I once received the first place prize in an (unsanctioned, online) Magic tournament that lasted a total of ten rounds (seven rounds of Swiss pairings, plus three single elimination rounds) but only beat an opponent at Magic during four of them.
3) I've beaten Battletoads, on an actual NES, without using a Game Genie or other cheat device.
4) Not too long ago, I made a $500 donation to Population Services International, using my debit card. Unfortunately, this overdrew my checking account. My parents were not pleased, not only because I overdrew my checking account, but also because they disapproved of my donating such a large amount of money.
5) My favorite Star Wars movie is "Attack of the Clones."
(Note: I used a random number generator to determine which position would contain the lie.)

I like this game, but you've got to make it interesting. In that vein, here's mine:
1) Eliezer once wrote an Overcoming Bias post where he said something like "Make one little mistake in a whole long chain of inferences, and you end up in Outer Mongolia." The first time I read this post was from a webcafe in Outer Mongolia.
2) I have pet several full-grown tigers, and one of them almost fell asleep on my lap.
3) I once broke up with a girl partly because she was a deontologist.
4) One of my school teachers once accused me, in all seriousness, of being a witch. Not witch as in "Wiccan", but witch as in "has magic powers and consorts with the devil".
5) I was given a blessing by a Tibetan lama in the mountains of Nepal.

When you're reasoning out new knowledge in the absence of crushingly overwhelming guidance, you can miss one point and wake up in Outer Mongolia fifty steps later.

If we're being strict then #1. Though the name's still informally used to refer to Mongolia, there's really been no such place as Outer Mongolia during any period of history in which it's likely to have contained a webcafe.
If we're not then I'd guess #2, as your favorite David Berman thought experiment involves clearly and distinctly imagining tigers.

1) I have the complete Feynman Lecture Series
2) I have beaten professional Counter-Strike players while never having played in any tournaments or leagues.
3) I am a smoker (cigarettes).
4) I never finished Half-Life.
5) My watch has Mickey Mouse on it (his hands point to the time!).

I think it's (2). To win a 7/SS+top 8 tournament, you would definitely need at least 4 and probably 5 wins in the main tournament, plus three wins in elimination. The rules of the Swiss system don't allow any player to receive more than one bye, so you would need to have had 4 wins, 1 bye, and at least 2 but probably 3 forfeits. Online tournaments may be different, but of all the Swiss tournaments I've played in, I have only ever seen one forfeit, so the same player getting multiple forfeits is highly unlikely.

Only piece of information we're missing is how many people started in the tournament which would allow us to find out how many points he would need to get top8.
You sound like you know what a Magic tournament is about way more than I do (don't know what counts as a draw, or if there even is such a thing) and have revised my estimates accordingly.
(1) .1 (2) .35 (3) .35 (4).18 (5).02
5 is low due to pjeby's comment, the .02 is my probability that he would slash my tires or is wrong.

Draws are possible in Magic (kill both players at the same time), but they're quite rare. Unless for some reason you wanted to draw instead of win, in which case you could do so intentionally.
In an online tournament, in addition to anything the tournament format itself allows, there's always another way to get eliminated: disconnect / failure to show up. I don't remember the disconnect rate in Magic online being particularly high, but a tournament does involve a significant amount of time for people to misplan.
Replies from: jimrandomh↑ comment by jimrandomh · 2009-04-18T03:31:37.217Z · LW(p) · GW(p)
Drawn games are rare, but drawn matches are fairly common. A match is drawn if it runs over the time limit without either player winning, or if it's best 2 of 3 and each player has one win when the time limit is reached.
I didn't consider disconnects. Those would tend to greatly increase the forfeit rate, over the forfeit rate I observed from in-person tournaments.
↑ comment by jimrandomh · 2009-04-18T01:46:14.518Z · LW(p) · GW(p)
We don't know how many people were in the tournament, but we do have a very good proxy: the number of rounds in the Swiss portion. Swiss tournaments are supposed to have between log_2(P) and log_2(P)+1 rounds, where P is the number of players, so the tournament had between 64 and 128 players.
comment by gjm · 2009-04-17T23:22:51.701Z · LW(p) · GW(p)
My (crude) probability assignments for which one is the lie: 0.15, 0.1, 0.15, 0.1, 0.5. I know nothing about Magic and have never even heard of Battletoads, but I'll assume that #3 is impressive because otherwise you wouldn't have chosen it.
(My immediate reaction to your list: The lie must be #5 because the other statements are merely somewhat improbable whereas that one is an actual logical impossibility.)

The game works better (at least as an inference game) if you make the wrong statement very wrong and not just a little bit wrong. And I've never seen the appeal of Fgne Jnef either.

Maybe we should modify the game so that the lie has to be the approximate opposite of something that's true? (Actual opposite when used in a logic class.)

My rule is a restriction to prevent an underwhelming reveal, not a heuristic for choosing good lies.
If you're interested in the subject of choosing good lies: All of your statements (whether they are truth or false) should be statements that are unlikely to describe a randomly chosen person. That's why the witchcraft one would not make a good truth or lie.

comment by Jordan · 2009-04-18T06:03:45.971Z · LW(p) · GW(p)
I guess #1. Here are my five:
1) I've climbed Pão de Açucar
2) Every man I've kissed has been dressed like a woman
3) I've never had a single tooth cavity
4) I once hung off the wing of a plane (that was flying)
5) I'm going bald

Well, by devoting so much explanation to 2, you make it pretty clear that's not it (or you're just a very good faker.) I guess (.1, .1, .1, .5, .2)
↑ comment by CronoDAS · 2009-04-19T03:50:12.500Z · LW(p) · GW(p)
My analysis:
1) Pão de Açucar is in Rio de Janeiro, Brazil, and, according to Wikipedia, is climbed by a lot of people. I have no reason to consider this any more unlikely than any other random statement someone might claim.
2): This seems plausible, if we assume that Jordan is male. I wouldn't be surprised to find at least some men dressed like women during an event like Carnival. Another not too weird circumstance in which this might happen is if both men are actors, and the kiss is during a performance.
3): Unusual, but possible. Again, this doesn't throw up any more red flags.
4): This is just plain weird, and seems to be the least plausible. Indeed, is that even physically possible?
5) This is very common.
I guess that #4 is the lie.

Well, the plane was too small to jump out of directly without hitting the tail, so first I had to grab the wing and work my way to the tip before letting go. I've got to say, however much of a rush skydiving is, hanging from a wing is way more exhilarating.
The lie was (1), it's definitely something I'd like to do, just haven't got around to it.
↑ comment by MrHen · 2009-04-18T14:32:24.594Z · LW(p) · GW(p)
I would guess #2 due to ambiguous clothing definitions. What does "dressed like a woman" mean?

Replies from: Jordan↑ comment by Jordan · 2009-04-18T22:44:09.729Z · LW(p) · GW(p)
I suppose I could clarify:
Every man I've kissed has been dressed in clothing traditionally accepted by Western culture to be feminine and moreover this group is nonempty.
Likewise by (3) I don't mean that every time I've had a cavity I've had at least two.
