Pseudoscience

Pseudoscience is anything that pretends to be science but is not.Gardner M. 1957. Fads and fallacies in the name of science. 2nd ed. Mineola, NY: Dover Publications. ISBN 978-0-486-20394-2. Originally published 1952 by G.P. Putnam's Sons, under the title In the Name of Science.Goldacre, Ben 2008. Bad science. London: Fourth Estate. ISBN 978-0-00-728487-0 Together, "pseudo-" and "science" mean "fake science." Pseudoscience may fail one or more parts of being scientific. 

Pseudoscience is not just an idea that is not accepted by the mainstream scientific community. It is an idea not open to testing, no matter what evidence against it is available. Although  the word means "false science," the openness to testing is fundamental to science. That is more fundamental than whether a theory is accepted. After all, ideas have been proved wrong though they were once were believed to be true. Obviously, science is not always right but always open to correction, which makes a clear difference between science and pseudoscience.Popper K. 1959. The logic of scientific discovery. Routledge. ISBN 978-0-415-27844-7

There is a difference, however, between pseudoscience and religion. Astrology is a pseudoscience because it pretends to be based on facts but is not. Religions make statements which are certainly not scientific and are not meant to be. Insofar as a religion makes no factual claims, it is not open to refutation. When a religion makes factual claims, it is vulnerable. A good example is the decision of the Catholic Church to defend Ptolemy's ancient ideas of the heavens against the ideas of Galileo and Copernicus, which were then new.

 Types of pseudoscience 

Ideas (more properly "hypotheses") about how nature works may be considered pseudoscientific for many reasons.Bunge M. 1983. Demarcating science from pseudoscience. Fundamenta Scientiae. 3: 369–88.Bunge, Mario Augusto 1998. Philosophy of Science: from problem to theory. Transaction Publishers. p. 24. ISBN 978-0-7658-0413-6  Sometimes, the hypothesis is just simply wrong, and can be demonstrated to be wrong.  Examples include the belief that the Earth is flat or that human female skeletons have one more rib than those of males.  Such ideas such are considered unscientific because they have been proved wrong.

Sometimes, an idea might be true but could never be demonstrated to be true, even in principle.  For example, suppose some people believe that the Earth and the universe came into existence last Thursday.  They may claim that when the universe came into existence last Thursday, it was created with the appearance of being many millions of years old.  According to those believers, even our memories of two weeks ago are actually just false memories, created along with the creation of the universe, which took place last Thursday.  Such a belief is considered pseudoscientific because it is not falsifiable since no experiment could shed light on whether this belief is true or false.

Other types of pseudoscience are considered pseudoscientific because they are based on deception even though the idea being used is not impossible. Examples are people who claim to have made time travel devices, antigravity devices, or teleporters. Scientists simply do not currently have the technology to build such things even though they may be able to someday.

Some ideas are arguably pseudoscientific. That means that some mainstream scientists consider the idea pseudoscientific and some do not. Certain ideas about how the stock market behaves fall into this category.

Pseudoscience is not exactly the same thing as biased research in which scientists have a bad motive (such as personal gain, fame, or financial profit) for promoting their findings. It is also not the same as an untested hypothesis, an idea that scientists cannot test yet because they do not have the money or technology to do so. The theories of quantum gravity are untested hypotheses since scientists can easily imagine experiments to test them, but they do not have the technology to do so at this time.

 Borderline pseudoscience 
Examples of ideas that are not accepted by scientists but still have some credibility today are dowsing (rhabdomancy, searching for water under the ground by "reading" a wooden stick) ; parapsychology or psychical research (communication in ways which is not accepted by science); and psychoanalysis (wholesale acceptance of Sigmund Freud's ideas).

 Other pseudoscholarship 
Pseudoscholarship is anything that pretends to be scholarly and academic but is not. There are many kinds, including pseudoscience:

 Pseudoarcheology is anything that pretends to be proper archeology but is not.
 Pseudohistory is anything that pretends to be proper history but is not.
 Pseudomathematics is anything that pretends to be proper mathematics but is not.
 Pseudophilosophy is anything that pretends to be philosophy but is not.
 Pseudopsychology is anything that pretends to be proper psychology but is not.
