Aug 3 2010: Probably someone pointed it out already, so it will be just +1, but could you, please, explain me, what actually is irrational in behaviour she described?
Those are completely different examples. If scientists wanted to analyze irrationality (or rationality in this case), they should have given such choices: sometimes plus 3, sometimes plus 1 OR always plus 2 grapes. The point is, what "sometimes" mean here statistically. If it's 50/50 - no big deal, both are the same, but for equal supply chain option 2 is better. In any other case - there's very rational explanation for choosing the right option, but people/monkeys will need time to decide.
Now, loosing. This behaviour, if "sometimes" was 50/50, was just as rational, as would be the other. In the long run, you get the same. Choosing one depends on your personal goals.
She hasn't said anything new. And Dan Ariely did it better. Gush, they probably were paid for this "research" with taxpayers money. Hope they saved it.
