Laurie Santos: How monkeys mirror human irrationality
wie Sie tun, machen, Film, Beispiel
http://www.ted.com Why do we make irrational decisions so predictably? Laurie Santos looks for the roots of human irrationality by watching the way our primate relatives make decisions. A clever series of experiments in "monkeynomics" shows that some of the silly choices we make, monkeys make too.

I Love Monkeys

One study and a lot of talk. The one thing I took from this is that she does not like financial advisors. Most people who dislike financial advisors want all the gains without any risk, which is impossible. Maybe a monkeys expectations are closer to reality than hers.

EV for grepes
1) (2x100%)=2
2)(1x50%)+(3x50%)=2
So both choices are equal. In long term monkeys will get 2 grapes on average.
The same with money - both choices are equal.
1)(1000x50%)+(2000x50%)=1500$
2)(1500x100%)=1500$
I have good news for everybody. We can easily overcame relativity and loss aversion biases just by using a math when it's possible. -
Can someone explain me why taking a 50% risk of loosing 1000 is a more rational choice than taking a 100% loss of 500. Because I don't see how any choice is better than other and so this video carry no message to me.

1 experiment and all these talk ?

Experimental economics has been doing similar work for an extremely long time. Check out Art DeVany or Ray Battalio's work.

Funny how she didn't mention the part about the monkey prostitution.....

I would like to see this scholar teamed up with Lara Broderinsky. I think the insights
could be very productive indeed. -
I knew it! I always said that the economy could be better managed by an ape!

there is big mistake in this...
first option: in average you can get 1000 usd (0+2000)/2 or 1500, so people chose 1500.
second option: in average you can get 1500 usd (2000+1000)/2 or 1500... so people can afford little risk -
i wonder what the monkeys would do with the tokens, if they were given some to hang on to when they left the market. do you think they would save them for next time? or maybe start trading them amongst them selves for stuff or favours like grooming and sex? monkey currency is fascinating. :)

Just goes to show I'm not human.
