A new study finds that women with the astrological sign Virgo are more likely to vomit when pregnant, and Libras are at greater risk for a fractured pelvises.

The conclusions are hogwash, it’s lead researcher will tell you.

“Scientists take pains to make sure their clinical studies are conducted accurately,” explains Peter Austin of the Institute for Clinical Evaluative Sciences in Toronto, “but sometimes erroneous conclusions will be obtained solely due to chance.”

At this week’s meeting of the American Association for the Advancement of Science, Austin used his flawed research to illustrate why it’s dangerous to base scientific decisions on the results of one study. The conclusions in his study are an example of the statistical chance that allows for erroneous associations. What makes for solid conclusions is when a study’s results can be replicated by other researchers and other methods.

“Replace astrological signs with another characteristic such as gender or age, and immediately your mind starts to form explanations for the observed associations,” Austin said. “Then we leap to conclusions, constructing reasons for why we saw the results we did. We did this study to prove a larger pointóthe more we look for patterns, the more likely we are to find them, particularly when we donít begin with a particular question”

Other studies (if you can believe them) say a third of all medical studies are wrong, and even when the scientists get it right, the media omits basic facts in medical stories.
