Scientific analysis and criticism
What two creations of confirmation bias are under study with respect to astrological belief?
Astrology
Astrology has been rejected by the scientific community as having no explanatory power for describing the universe. Scientific testing of astrology has been conducted, and no evidence has been found to support any of the premises or purported effects outlined in astrological traditions. There is no proposed mechanism of action by which the positions and motions of stars and planets could affect people and events on Earth that does not contradict well understood, basic aspects of biology and physics. The majority of professional astrologers rely on performing astrology-based personality tests and making relevant predictions about the remunerator's future. Those who continue to have faith in astrology have been characterized as doing so "in spite of the fact that there is no verified scientific basis for their beliefs, and indeed that there is strong evidence to the contrary". It has also been shown that confirmation bias is a psychological factor that contributes to belief in astrology. Confirmation bias is a form of cognitive bias. From the literature, Astrology believers often tend to selectively remember those predictions which have turned out to be true, and do not remember those predictions which happen to be false. Another, separate, form of confirmation bias also plays a role, where believers often fail to distinguish between messages that demonstrate special ability and those which do not. Thus there are two distinct forms of confirmation bias that are under study with respect to astrological belief.
