Europe: Astrology as scientific as Economics [and more so than histroy!]
41% rated astrology either as 4-5 on a 1-5 scale with 4-5 representing "scientific" Economics, was barely behind with 40% and psychology beat out astrology with 53% [page 36 BTW] Oh and don't forget Homeopathy with a healthy 33% [To be fair, only 13% think horoscopes are scientific]
I found stats on American belief for comparision
Belief in pseudoscience is widespread. For example, at least a quarter of the U.S. population believes in astrology, i.e., that the position of the stars and planets can affect people's lives. Although two-thirds (66%) of those queried in 2004 said that astrology is "not at all scientific," about one-third considered it at least "sort of scientific" (appendix table 7-14 ).
So about ~33% of Americans would have said the same thing.
Also, 32% of Europeans don't understand science and 31% don't care enough to be interested in it [page 33].
