Occupying the 5th position in the Chinese Zodiac, the Dragon is the mightiest of the signs. Dragons symbolize such character traits as dominance and ambition. Dragons prefer to live by their own rules and if left on their own, are usually successful. They’re driven, unafraid of challenges, and willing to take risks. They’re passionate in all they do and they do things in grand fashion. Unfortunately, this passion and enthusiasm can leave Dragons feeling exhausted and interestingly, unfulfilled. While Dragons frequently help others, rarely will they ask for help. Others are attracted to Dragons, especially their colorful personalities, but deep down, Dragons prefer to be alone. Perhaps that is because they’re most successful when working alone. Their preference to be alone can come across as arrogance or conceitedness, but these qualities aren’t applicable. Dragons have tempers that can flare fast! excerpted from http://www.chinesezodiac.com/dragon.php
Just reading that description gives my self-esteem a (clearly superfluous) boost. Being a scientist, however, I can’t quite commit to the belief whole-heartedly. And given that we’re about to enter another year of the Dragon on Monday, it’s only fair to look at the evidence. Is there any compelling proof that the Chinese zodiac predictions are worth considering?
First, the caveat. Being a skeptical person by nature, and a psychologist by training, my working hypothesis is that the signs appeal to the vast majority of people, because the traits associated with a given sign include virtues of personality that we all share, or revere, alongside their equally-universal vices. Take the dragon, for example: in general, most people aspire to success and are passionate about, well, something. Most people prefer to live by their own rules and take solace in the notion that because they have to follow someone else’s rules to some extent (either at work, home or play), they are not as successful as they could be. And sure, if you’re ambitious, driven, self-motivated and prefer to be alone, you are likely to be perceived as arrogant and you certainly will feel exhausted at times. Going through the list of personality traits on the Chinese Zodiac page of Wikipedia, I find myself represented to some extent by each one of the signs. That is, of course, if I indulge in my natural tendency towards searching for confirming rather than disconfirming evidence, which psychologists call the confirmation bias. If I assess the extent to which these description fit my character, rather than the extent to which they miss key components of my personality, I can become quite convinced.
But enough speculation. What do the data show? Oddly enough, there aren’t that many studies of the effects of the Chinese Zodiac on pubmed. But those brave scientists who have published such studies have made some pretty fascinating discoveries. Giving the importance and unpredictability of childbirth, it comes as no surprise that the Chinese Zodiac is often used to gage whether a woman will become pregnant in a given year, and what will be the sex of the child. To test whether the zodiac does indeed correlate with its own predictions, Jungmin Lee and Myungho Park investigated the sex preferences and fertility in South Korea in the Year of the Horse and published their results in 2006. The horse is associated with masculinity and, in South Korea at least, the year is considered inauspicious for girls, as they are thought to suffer unhappiness and misfortune. Certainly, these predictions have as much to do with the society in which these girls are born as they have to do with the moon: as the authors point out, ‘in patriachal and Confusionist societies, women are expected to be subservient to men’. (Pardon me while I expel some smoke via my nostrils). Is there any evidence that the year of the Horse correlates with a higher birth rate of boys? Is it such a strong force that women might avoid getting pregnant and show a decrease in fertility? The authors seem to think so.
I must admit that those years don’t strike me as significant outliers. But what about the year of the dragon? In many Asian cultures, the dragon is considered (ahem) the best sign (though not so much for the ladies). In Hong Kong, birth rates peaked in the 1980s and then started to decline, even though the numbers of married women of child-bearing age continued to increase. Every 12 years, however, a blip in births was observed, coinciding with the year of the Dragon. In 2002, Yip, Lee and Cheung published a study of birthrates in Hong Kong in the journal Social Science and Medicine. These data seem more convincing to me, especially because Taiwan and Singapore both saw large increased in birth rates in the two previous dragon years.
But how can we assess
whether these effects are mainly driven by human
behavior or by the orbit of the moon? Luckily,
another study was recently published,
which assessed the accuracy of predictions by the
Chinese Lunar Calendar on 2.8 million Swedish
births between 1973 and 2006. Such a huge database
is pretty compelling and I’ll let the authors
speak for themselves: ‘We conclude that the CLC
method is no better at predicting the sex of a
baby than tossing a coin and advise against
painting the nursery based on this method's
result.’ There you have it. Once again, you’ll see
it if you believe it. That is, belief in the
zodiac will alter your behavior, such that it
becomes a self-fulfilling prophecy. Off I go then,
to follow my ambitions and take risks. Happy
Chinese New Year and best of luck in 2012!
