In some ways, astrology may seem scientific. It uses scientific knowledge about heavenly bodies, as well as scientific sounding tools, like star charts. Some people use astrology to generate expectations about future events and people's personalities, much as scientific ideas generate expectations. And some claim that astrology is supported by evidence — the experiences of people who feel that astrology has worked for them. But even with these trappings of science, is astrology really a scientific way to answer questions?
Here we'll use the Science Checklist to evaluate one way in which astrology is commonly used. See if you think it qualifies as scientific!
Focuses on the natural world?
Astrology's basic premise is that heavenly bodies — the sun, moon, planets, and constellations — have influence over or are correlated with earthly events.
Aims to explain the natural world?
Astrology uses a set of rules about the relative positions and movements of heavenly bodies to generate predictions and explanations for events on Earth and human personality traits.
For example, some forms of astrology predict that a person born just after the spring equinox is particularly likely to become an entrepreneur.
Uses testable ideas?
Some expectations generated by astrology are so general that anyoutcome could be interpreted as fitting the expectations; if treated this way, astrology is not testable.
However, some have used astrology to generate very specific expectations that could be verified against outcomes in the natural world.
For example, according to astrology, one's zodiac sign impacts one's ability to command respect and authority.
Since these traits are important in politics, we might expect that if astrology really explained people's personalities, scientists would be more likely to have zodiac signs that astrologers describe as "favorable" towards science.1 If used to generate specific expectations like this one, astrological ideas are testable.
Relies on evidence?
In the few cases where astrology has been used to generate testable expectations and the results were examined in a careful study, the evidence did not support the validity of astrological ideas.2 This experience is common in science — scientists often test ideas that turn out to be wrong.
However, one of the hallmarks of science is that ideas are modified when warranted by the evidence.
Astrology has not changed its ideas in response to contradictory evidence.
Involves the scientific community?
Sharing one's findings and critically evaluating the results of others are not integral parts of practicing astrology.
An astrologer can go his or her entire career and not present findings at a scientific meeting or publish a single article.
When astrologers do publish, these articles are not usually peer-reviewed or published in places where they will be critically scrutinized by the scientific community.
Leads to ongoing research?
Scientific studies involving astrology have stopped after attempting and failing to establish the validity of astrological ideas.
So far, there are no documented cases of astrology contributing to a new scientific discovery.
Researchers behave scientifically?
Scientists don't wait for others to do the research to support or contradict the ideas they propose.
Instead, they strive to test their ideas, try to come up with counterarguments and alternative hypotheses, and ultimately, give up ideas when warranted by the evidence.
Astrologers, on the other hand, do not seem to rigorously examine the astrological ideas they accept.
As reflected by the minimal level of research in the field, they rarely try to test their arguments in fair ways.
In addition, the astrological community largely ignores evidence that contradicts its ideas.
Their answer: Astrology is not a very scientific way to answer questions. Although astrologers seek to explain the natural world, they don't usually attempt to critically evaluate whether those explanations are valid — and this is a key part of science. The community of scientists evaluates its ideas against evidence from the natural world and rejects or modifies those ideas when evidence doesn't support them. Astrologers do not take the same critical perspective on their own astrological ideas.
