Chimpanzees Choose more Rationally than Humans


Tell us something we already don’t know … Chimps choose more rationally than Monkey-cushionhumans. In other words, Monkeys do not make irrational choices to punish someone they perceive as unfair. Its not a matter of getting even, its a matter of self interest and self preservation. End result when it comes to choice, monkeys are rational. So how does this rational decision making play into stories that have been commented on this site?

The researchers concluded chimpanzees do not show a willingness to make fair offers and reject unfair ones. In this way, they protect their self interest and are unwilling to pay a cost to punish someone they perceive as unfair.

And sometimes Monkeys choose even more rationally than certain humans.

LEIPZIG, Germany, Oct. 8 (UPI) — German researchers have demonstrated chimpanzees make choices that protect their self-interest more consistently than do humans.

Researchers from the Max Planck Institute of Evolutionary Anthropology in Leipzig studied the chimp’s choices by using an economic game with two players. In the game, a human or chimpanzee who receives something of value can offer to share it with another.

If the proposed share is rejected, neither player gets anything

      My own personal feelings on the subject is that the animal kingdom, including chimpanzees, act on instinct that is usually based on “Mother Nature’s” rule of self preservation.

      As human’s, we have the right to choose between right and wrong. Our thought processes are much more complex in dealing with several factors that dictate our choices. A few examples are conscience, ego, super ego and ofcourse id, the function that is most prevalent in animals. As bad as we can be, sometimes, we really do excel over the animals in reasoning skills and in intelligence… some of us just don’t act like it sometimes.

      A chimp is not a monkey.
      SM: Get over yourself Yoyo –

      Because of their similarity to monkeys, apes such as chimpanzees and gibbons are often called monkeys in informal usage, though they are not monkeys

      I would consider this informal usage wouldn’t you Yoyo? (klaasend)

      Don’t let anyone make a monkey out of YOU …

      (well, unless you’re already a scared one, that is; and if you’re not, join us!)


      It’s worse than the jungle.
