However, you should only put yourself in this situation if you can generally outplay the rest of the table by more than enough to negate your disadvantage against the shark; otherwiseChristopher Changhttp://www.facebook.com/profile.php?id=723726480noreply@blogger.comtag:blogger.com,1999:blog-5880610.post-79962383668684695022011-05-04T21:33:04.661-04:002011-05-04T21:33:04.661-04:00"... we assume that each player is rational f..."... we assume that each player is rational from some perspective"<br /><br />If that includes crashing a 747 into a skyscraper because of something you believe about the afterlife, then I suggest it's not much of a constraint on decisions / actions in this life.steve hsuhttp://duende.uoregon.edu/noreply@blogger.comtag:blogger.com,1999:blog-5880610.post-68920922308482168112011-05-04T21:17:00.659-04:002011-05-04T21:17:00.659-04:00@Dave and Vic

The early researchers in decision and game theory thought they might actually solve this problem but it's obvious they cannot. Is the goal (normative) to define what a "rational" person "should do" in a particular situation?

Game theory models scenarios of strategic competition. People in such real-world scenarios are more likely to make decisions rationally than they are other contexts, I suspect.
