«In a nutshell: Astrology is the idea that the stars, planets, and other objects in the sky shape who you are and what your life will be like. The science doesn’t favor this idea.»
Astrology is a kind of fortune telling based on the positions of stars, planets, and other objects in the deep sky (called celestial objects). Astrologers believe that the position of celestial objects affect what kind of personality you have and also cause such things as forest fires, floods, volcanoes, earthquakes, hurricanes, and tornadoes.
Astrology is sometimes confused with astronomy, which is the scientific study of planets, the Sun, stars, comets, galaxies, and other things outside of the Earth’s atmosphere. Astronomers know that celestial objects like the Moon and the Sun affect the ocean tides but have nothing to do with what kind of personality you have. Astronomers also know that the position of celestial objects has nothing to do with such things as forest fires, floods, volcanoes, earthquakes, hurricanes, and tornadoes.

Thousands of years ago in Babylon (now in modern Iraq) astrologers charted out the path that the Sun seems to make around the Earth. They divided the path into twelve equal parts. The stars in some of the twelve parts of the sky looked like the outlines of animals to them. The chart is called a zodiac (Greek for circle of animals). I was born when the Sun was in a part of the sky where the stars looked sort of like the outline of a bull’s head to those who were charting the zodiac. According to Sun sign astrology, I am a Taurus. The bull has a reputation for being stubborn. Sun sign astrologers believe that those born under the sign of the bull will have bull-like qualities. Scientific skeptics think this idea is a bunch of bull. When I’m asked what sign I was born under, I say “St. Joseph’s Hospital.”

In addition to Sun sign astrology, there are several other astrologies, but none of them are scientific. All systems of astrology make unscientific claims about the effects on people or things on Earth by the positions of planets, comets, and other things in the sky.
Confirmation bias: Selective thinking whereby one tends to notice and to look for what confirms one’s beliefs, and to ignore, not look for, or undervalue the relevance of what contradicts one’s beliefs.
Some of these systems are very complicated and involve making charts that connect the positions of many different celestial objects. With many charts covering many different possibilities, it is easy to find one that matches something on Earth like a forest fire, an earthquake, or a tragedy in some famous person’s life.
It is also easier than most people think to find evidence in support of a strong belief. We pay attention to what agrees with our beliefs and ignore what goes against them. If you believe that people born under the sign of Taurus are stubborn, you might pay more attention to stubborn behavior by someone born under that sign. You might even call that person stubborn for not doing something, while calling another person firm for not doing the same thing. You might not pay attention to or remember a Taurus when she isn’t stubborn. Psychologists call this natural bias we have to confirm our beliefs confirmation bias.
Astrologers sometimes make accurate predictions that are really nothing more than lucky guesses. Many astrologers believe that comets, the alignment of planets, or an eclipse are omens that something terrible is going to happen on Earth. Since something terrible happens on this planet every day, it is always easy to find something after the fact that the astrologer can say was predicted.
