Re: Money isn't everything
- I was amused by the article when I read it.
One of the questions I have when I read of economic experiments is
the context - how realistic (relevant to what we see and do in real
life) is the arranged situation?
I'm familiar with the ultimatium game and the normal rationale of the
participants, that it is free money for both, therefore the money
should be split 50/50%. The 60/40% vs 87.5/12.5% offer/accept
scenario is an extreme difference, but we can probably find a real
life example somewhere that is similar.
I agree that people think more in terms of seeking relative than
absolute prosperity, but I still don't know about the correct
relative weight of sociobiology rationales or cultural/social
conditioning as the best way of explaining it.
