I'm sure a few people on here have been watching Survivor. If you haven't, the premise is that 16 people are deserted on an island and filmed. Every three days, someone is voted off of the island by the others. The last two people left are voted on by the previous seven who were there. The winner gets one million dollars.

Now, aside from all the strategies I've heard about how to win/survive, it appears that the only successful way to win is to lie at some point during the 39 days on the island (i.e. telling person A you are going to vote for person B to get booted but actually voting for person A). First of all, do you think that someone could win without ever lying? Second, is lying acceptable in this situation? Why?

Bonus question: Do you think a person who would never lie outside of this situation would lie because of the money or because it is a TV/Game Show where the rules are different?
