From Mother Jones: More and More Americans Think Astrology Is Science
The data on Americans' astrological beliefs are compiled by NSF but come from a variety of sources; since 2006 they have come from the General Social Survey. Over the years, the GSS and other surveys have asked Americans a recurring question: "Would you say that astrology is very scientific, sort of scientific, or not at all scientific?"
In response, a substantial minority of Americans, ranging from 31 to 45 percent depending on the year, say consider astrology either "very scientific" or "sort of scientific." That's bad enough—the NSF report compares it with China, where 92 percent of the public does not believe in horoscopes—but the new evidence suggests we are also moving in the wrong direction. Indeed, the percentage of Americans who say astrology is scientifically bunk has been declining ever since a high point for astrology skepticism in 2004, when it hit 66 percent.
The recent increase in astrological credulity was most dramatic among those with less science education and less "factual knowledge," NSF reported. In the latter group, there was a staggering 17 percentage point decline in how many people were willing to say astrology is unscientific, from 52 percent in 2010 to just 35 percent in 2012. Also apparently to blame are younger Americans, aged 18 to 24, where an actual majority considers astrology at least "sort of" scientific, and those aged 35 to 44. In 2010, 64 percent of this age group considered astrology totally bunk; in 2012, by contrast, only 51 percent did, a 13 percentage point change.
Here's a breakdown of the changes in Americans' astrology beliefs by age group:
