Astrology: More like Religion Than Science

By Sharon Hill via The Committee for Skeptical Inquiry (CSI)

I’ve discussed here and here how practitioners of paranormal piffle wish to look scientific. They fail under actual scientific scrutiny but, we have to admit, they are pretty effective at bamboozling the public with a sciencey show.

I came across a news story in Business Insider about an astrologer who was doing mighty well for herself. In times of uncertainty, society tends to turn to anything that will give them a sense of control. Astrologic and psychic advisors seem to fill that role for some people, even professional businesspeople. This astrologer, who thinks quite highly of her craft, had these things to say:

“What I do is scientific. Astrology involves careful methods learned over years and years of training and experience.”

“There are so many things we don’t understand in the world. What if 200 years ago someone had said that these metal barrels in the sky would get us around the world in a few hours? Or that we’d inject ourselves with mold to treat illnesses? People are so skeptical.”

And then I laughed.

Few examples of pseudoscience are more perfect than astrology, which has been studied A LOT, and whose practitioners still cannot demonstrate a root in reality.

Dowsing (a.k.a. water witching)

Via The Skeptic’s Dictionary

dowsing1Dowsing is the action of a person–called the dowser–using a rod, stick or other device–called a dowsing rod, dowsing stick, doodlebug (when used to locate oil), or divining rod–to locate such things as underground water, hidden metal, buried treasure, oil, lost persons or golf balls, etc. Since dowsing is not based upon any known scientific or empirical laws or forces of nature, it should be considered a type of divination and an example of magical thinking. The dowser tries to locate objects by occult means.

Map dowsers use a dowsing device, usually a pendulum, over maps to locate oil, minerals, persons, water, etc. However, the prototype of a dowser is the field dowser who walks around an area using a forked stick to locate underground water. When above water, the rod points downward. (Some dowsers use two rods. The rods cross when above water.) Various theories have been given as to what causes the rods to move: electromagnetic or other subtle geological forces, suggestion from others or from geophysical observations, ESP and other paranormal explanations, etc. Most skeptics accept the explanation of William Carpenter (1852). The rod moves due to involuntary motor behavior, which Carpenter dubbed ideomotor action.

In the 16th century, Agricola described mining dowsers using a forked twig to find metals (De re metallica). He didn’t think much of the practice. A miner, he wrote:

should not make us of an enchanted twig, because if he is prudent and skilled in the natural signs, he understands that a forked stick is of no use to him, for … there are natural indications of the veins which he can see for himself without the help of twigs. (Quoted in Zusne and Jones 1989: 106)

Despite this sage advice, dowsers continue to dowse, claiming that they have a special power and that what they are dowsing for emanates energy, rays, radiations, vibrations, and the like.

Does dowsing work?

Some people are less interested in why the rods move than in whether dowsing works. Obviously, many people believe it does. Dowsing and other forms of divination have been around for thousands of years. There are large societies of dowsers in America and Europe and dowsers practice their art every day in all parts of the world. There have even been scientists in recent years who have offered proof that dowsing works. There must be something to it, then, or so it seems.

Debunked: Astrology and Horoscopes


astrology_854_300pxOver 2300 years ago, the Babylonians came up with the idea that the gods lived among the stars and other celestial objects, and were able to impose their will on humanity by controlling the destinies of individuals and nations alike.  The Babylonians divided the sky into 12 “slices”:  which we now know as the signs of the zodiac… Taurus, Pisces, etc.  There are many variations of astrology, but they are all founded upon the idea that celestial objects can influence a person’s personality and destiny.

Today, according to a Gallup poll, 25% of American believes in Astrology.  In this article, we’ll investigate why horoscopes and astrology sometimesappear to be correct by reviewing the concept of subjective validation, the Forer Effect, and Gauquelin’s famous horoscope experiment; we’ll take a look at what an astronomer has to say about astrology;  we’ll review some of the logical issues with astrology; and finally, we’ll take a look at how easy it is to debunk horoscopes yourself.

Subjective Validation and the Forer Effect

crystal_ball_01“Subjective validation” occurs when two unrelated or random events are perceived to be related because a belief, expectancy, or hypothesis demands a relationship. Thus, people find a connection between the perception of their personality and the contents of their horoscope.

The concept of subjective validation was put to the test in 1948 by psychologist Bertram R. Forer.  Forer gave a personality test to each of his students. Afterward, he told his students they were each receiving aunique personality analysis that was based on the test’s results, and to rate their analysis on a scale of 0 (very poor) to 5 (excellent) on how well it applied to themselves.

The analysis presented to the students was as follows:

You have a great need for other people to like and admire you. You have a tendency to be critical of yourself. You have a great deal of unused capacity which you have not turned to your advantage. While you have some personality weaknesses, you are generally able to compensate for them. Disciplined and self-controlled outside, you tend to be worrisome and insecure inside. At times you have serious doubts as to whether you have made the right decision or done the right thing. You prefer a certain amount of change and variety and become dissatisfied when hemmed in by restrictions and limitations. You pride yourself as an independent thinker and do not accept others’ statements without satisfactory proof. You have found it unwise to be too frank in revealing yourself to others. At times you are extroverted, affable, sociable, while at other times you are introverted, wary, reserved. Some of your aspirations tend to be pretty unrealistic. Security is one of your major goals in life.

zodiac-sun-eye_250pxThe trick?  In reality, each student received the exact same analysis:  On average, the rating was 4.26/5(that is, the students found their “personal” analysis to be 85% accurate).  It was only after the ratings were turned in was it revealed that each student had received identical copies assembled by Forer from various horoscopes.

As can be seen from the profile analysis, there are a number of statements that are vague and could apply equally to anyone. These statements later became known as Barnum statements, after P.T. Barnum, who used them in his performances, allegedly stating “there’s a sucker born every minute.”

Later studies have found that subjects give higher accuracy ratings if the following are true:

  • the subject believes that the analysis applies only to him or her (for example, a horoscope)
  • the subject believes in the authority of the evaluator (for example, a psychic)
  • the analysis lists mainly positive traits (for example, most daily horoscopes)

Guaquelin’s Horoscope Experiment

Mass murderer

Dr. Marcel Petiot

In another experiment, the famous French Astrologer, Michael Gauquelin, offered free horoscopes to any reader of Ici Paris, if they would give feedback on the accuracy of his supposedly “individual” analysis. He wanted to scientifically test the profession of astrology. As with Forer’s experiment, there was a trick:  he sent out thousands of copies of the same horoscope to people of various astrological signs – and 94% of the readers replied that his reading was very accurate and insightful.

What they didn’t know was that the horoscope was that of a local mass murderer, Dr. Petiot, who had admitted during his trial that he had killed 63 people.  This is clearly another case of subjective validation where subjects focus on the hits of some general analysis that’s supposed to be unique to them.
