I think many people have heard this story before:
Five monkeys are caged together and there are some bananas hanging from the top of the cage. Some scientists attach an automated device for sensing if the bananas are moved; once a monkey tries to get any, an electric shock travels through the cage so that all monkeys get shocked. In the beginning, a single monkey climbs up to the bananas, touches them and every monkey gets shocked. So he doesn’t try anymore, but the other four monkeys try the same thing and the result comes to be the same. Therefore, the monkeys learn something in common: that is, do not get the bananas! You’ll get a painful electric shock! The scientists then replace one of the original monkeys with a new one. This new monkey sees the bananas and wants to get them right away, but the other four monkeys beat it when they see its actions. Since these original four monkeys think the new monkey will make them get shocked, they stop the new monkey from getting the bananas. This monkey tries a few times and the others beat it every time without it ever getting the bananas. Of course, all five monkeys don’t get shocked. The scientists then replace another of the original monkeys with a new one. This second new monkey sees the bananas and you bet it wants to get them immediately. But, sadly, the others beat it and the first new monkey beats the newest one even harder then the others (for the newest one is the rookie and has the lowest social status). Just like before, the newest monkey tries several times to get the bananas and is stopped by the others when they attack him. The scientists continue to replace all the original monkeys until no monkeys who actually felt the electric shock remain. Now none of the five new monkeys dare to touch the bananas yet none of them know why. They only know whomever wants to get the bananas will be beaten.

An article called “Chinese villagers eat dinosaur bones” from several months ago has more interesting things to say. Villagers in central China dug up a ton of dinosaur bones and boiled them in soup or ground them into powder for traditional medicine, believing they were from flying dragons and had healing powers. Until last year, the fossils were being sold in Henan province as “dragon bones” at about 4 Yuan per kilogram, scientist Dong Zhiming said. Dong, a professor with the Institute of Vertebrate Palaeontology and Paleoanthropology of the Chinese Academy of Sciences, said when the villagers found out the bones were from dinosaurs they donated 200 kilograms to him and his colleagues for research. The calcium-rich bones were sometimes boiled with other ingredients and fed to children as a treatment for dizziness and leg cramps. Other times they were ground up and made into a paste that was applied directly to fractures and other injuries.

These days Eastern philosophies, exercise, and Chinese herbalism are getting popular in the West. There are many people learning Zen, Yoga, Tai Chi, Qi Gong, and Chinese medicine etc. This is because of the popular belief that, since these practices are steeped in tradition and have long histories, they are good. But how many of these practices have elements like the “dragon bones” of Chinese medicine…in reality being fossilized dinosaur bones changed by people’s imagination? For instance, Chinese traditionally believe that tiger’s penis can enhance sexual ability but now we know Viagra works much better.

Sakyamuni Buddha in the Kalama Sutra taught us like this:
I have heard that on one occasion the Blessed One, on a wandering tour among the Kosalans with a large community of monks, arrived at Kesaputta, a town of the Kalamas. The Kalamas of Kesaputta heard it said, “Gotama the contemplative — the son of the Sakyans, having gone forth from the Sakyan clan — has arrived at Kesaputta. And of that Master Gotama this fine reputation has spread: ‘He is indeed a Blessed One, worthy, & rightly self-awakened, consummate in knowledge & conduct, well-gone, a knower of the cosmos, an unexcelled trainer of those persons ready to be tamed, teacher of human & divine beings, awakened, blessed. He has made known — having realized it through direct knowledge — this world with its devas, maras, & brahmas, its generations with their contemplatives & priests, their rulers & common people; has explained the Dhamma admirable in the beginning, admirable in the middle, admirable in the end; has expounded the holy life both in its particulars & in its essence, entirely perfect, surpassingly pure. It is good to see such a worthy one.'” So the Kalamas of Kesaputta went to the Blessed One. On arrival, some of them bowed down to him and sat to one side. Some of them exchanged courteous greetings with him and, after an exchange of friendly greetings & courtesies, sat to one side. Some of them sat to one side having saluted him with their hands palm-to-palm over their hearts. Some of them sat to one side having announced their name & clan. Some of them sat to one side in silence. As they sat there, the Kalamas of Kesaputta said to the Blessed One, “Lord, there are some priests & contemplatives who come to Kesaputta. They expound & glorify their own doctrines, but as for the doctrines of others, they deprecate them, revile them, show contempt for them, & disparage them. And then other priests & contemplatives come to Kesaputta. They expound & glorify their own doctrines, but as for the doctrines of others, they deprecate them, revile them, show contempt for them, & disparage them. They leave us absolutely uncertain & in doubt: Which of these venerable priests & contemplatives are speaking the truth, and which ones are lying?” “Of course you are uncertain, Kalamas. Of course you are in doubt. When there are reasons for doubt, uncertainty is born. So in this case, Kalamas, don’t go by reports, by legends, by traditions, by scripture, by logical conjecture, by inference, by analogies, by agreement through pondering views, by probability, or by the thought, ‘This contemplative is our teacher.’ When you know for yourselves that, ‘These qualities are unskillful; these qualities are blameworthy; these qualities are criticized by the wise; these qualities, when adopted & carried out, lead to harm & to suffering’ — then you should abandon them.”

The Pali says “Traditions are not to be followed simply because they are traditions. Reports (such as historical accounts or news) are not to be followed simply because the source seems reliable. One’s own preferences are not to be followed simply because they seem logical or resonate with one’s feelings. Instead, any view or belief must be tested by the results it yields when put into practice; and — to guard against the possibility of any bias or limitations in one’s understanding of those results — they must further be checked against the experience of people who are wise. The ability to question and test one’s beliefs in an appropriate way is called appropriate attention. The ability to recognize and chose wise people as mentors is called having admirable friends. These are, respectively, the most important internal and external factors for attaining the goal of the practice.” This is explained as translated from the Pali by Thanissaro Bhikkhu 1998 and found on the Internet at Access To Insight.
