Better than any joke posted here for laughs and fundamental truths* exposed is this video: http://www.upworthy.com/2-monkeys-were-paid-unequally-see-what-happens-next?g=3
* including the basis for the Wall Street demonstrations / protests by mainly well off America compared to 95% of humanity.
Another "truth" well illustrated, but not mentioned, is the strong tendency to blame oneself for failing to do assigned task correctly when the promised or expected reward is not given (earned). I.e. after monkey did task (give rock to experimenter) and was not rewarded as expected the next time he was allowed to earn a reward, he first tested the rock to see if it was a "good solid rock" before giving it. I think he assumed that in the prior trial, his rock given was not good enough to earn the desired reward. - I.e. he assumed he did not do that prior task correctly. Recall this when things don't work out as you had hoped - Fault may be with "bad luck" or others, not with yourself.
Oh, I see, it was an excerpt from this ted talk. Frans de Waal: Moral behavior in animals.
That was awesome. I loved it!
Thanks, Billy!
