|Style over substance|
This is a list of fields of endeavors and concepts that have been regarded as pseudoscientific by (1) organizations that are representative of the international scientific community and/or (2) mainstream skeptical organizations. They may have explicitly called a field or concept "pseudoscience" or used words to that effect. Also included are important concepts associated with the main entries, and concepts that, while notable, have not elicited commentary from mainstream scientific bodies. Notable parodies of pseudoscientific concepts are also included.
 Main topics
The following have broad consensus concerning their pseudoscientific status. Indicative of this are assertions by mainstream, specialized scientific bodies.
- Astrology refers to any of several systems of understanding, interpreting and organizing knowledge about reality and human existence, based on the relative positions and movement of various real and construed celestial bodies.
- Planetary alignments are events where two or more planets and the Sun and Moon line up from the perspective of Earth. Much of astrology has been developed around such alignments.
- Sun signs are astrological signs that are determined by the location of the Sun at a particular moment in time such as an individual's birth.
- Austrian economics refers to a school of economic thought that eschews mathematical modeling and empirical testing in favor of a narrative approach termed 'praxeology.'
- Creation science is the belief that the origin of everything in the universe is the result of a first cause, brought about by a creator deity, and that this thesis is supported by geological, biological, and other scientific evidence. This "evidence" is either Biblical in nature, or it attacks a tenet of evolution, incorrectly assuming that if any part of evolution is wrong, the whole thing is wrong and creationism is right.
- Baraminology is an attempt to create a bible friendly version of species without invoking evolution.
- Biblical scientific foreknowledge asserts that the Bible makes accurate statements about the world that science verifies thousands of years later. A favorite of kdbuffalo/Conservative. Suffers from the problem that prophesy should predict the future, not the past. Kinda the whole point.
- Catastrophic plate tectonics
- Creationist cosmologies are ones which, among other things, allow for a universe that is only thousands of years old.
- Flood geology is the creationist form of geology that advocates most of the geologic features on Earth are explainable by a global flood.
- Intelligent Design is a version of creation science stated in secular terms, viz. that "certain features of the universe and of living things are best explained by an intelligent cause, not an undirected process such as natural selection."
- The Banana fallacy is an argument about how things are designed to suit humans, while ignoring other explanations such as artificial selection.
- Irreducible complexity is the claim that some systems are so complex that they cannot have evolved from simpler systems. It is used by proponents of intelligent design to argue that evolution by Natural selection alone is incomplete or flawed, and that some additional mechanism (an "Intelligent Designer") is required to explain the origins of life.
- Specified complexity is the claim that when something is simultaneously complex and specified, one can infer that it was produced by an intelligent cause (i.e., that it was designed) rather than being the result of natural processes.
- Modern geocentrism cites uniform gamma ray bursts distribution as evidence that we are at the center of the universe, and other ideas of this type.
- Crop circles are geometric designs of crushed or knocked-over crops created in a field. Aside from skilled farmers or pranksters working through the night, explanations for their formation include UFOs and anomalous, tornado-like air currents. The study of crop circles is termed "cerealogy" by proponents.
- Dogon people and Sirius B is a series of claims that the Dogon tribe knew about the white dwarf companion of Sirius despite it being invisible to the naked eye.
- Erich von Däniken's proposal of ancient astronauts.
- Full moon lunacy is the belief that the full moon is correlated with the manifestation of lunacy.
- Non-materialist neuroscience is the attempt to scientifically prove the existence of a "mind," and is closely related to dualism
- Paranormal subjects
- Channeling is the communication of information to or through a person allegedly from a spirit or other paranormal entity
- Dowsing refers to practices said to enable one to detect hidden water, metals, gemstones or other objects.
- Electronic voice phenomenon is the alleged communication by spirits through tape recorders and other electronic devices
- Extra-sensory perception is the paranormal ability (independent of the five main senses or deduction from previous experience) to acquire information by means such as telepathy, clairvoyance, precognition, psychic abilities, and remote viewing.
- Levitation, in this sense, is the act of rising up from the ground without any physical aids, usually by the power of thought.
- Materialization is the supposed creation or appearance of matter from unknown sources.
- Psychokinesis is the paranormal ability of the mind to influence matter or energy at a distance.
- Spiritualism is a religious movement which holds the belief that communication with the dead can occur through the powers of individuals called mediums.
- Seances are ritualized attempts to communicate with the dead.
- Perpetual motion is a class of proposed machines that violate the Second Law of Thermodynamics. Perpetual motion has been recognized as extrascientific since the late 18th century, but proposals and patents for such devices continue to be made to the present day.
- Torsion fields is a theory about some new kind of fields that travel much faster than light. The theory itself is based on the algebraic error in solving equations of theoretical mechanics. Torsion fields are often used to "mathematically describe" other pseudoscientific topics.
- Ufology is the study of unidentified flying objects (UFOs) and frequently includes the belief that UFOs are evidence for extraterrestrial visitors.
- The Face on Mars (in Cydonia Mensae) is a rock formation on Mars asserted to be evidence of intelligent, native life on the planet. Higher resolution images show it to appear less face-like. It features prominently in the pseudoscientific theories of Richard C. Hoagland.
- Alien abductions are events where people claim to have been taken into a spaceship for medical experiments by aliens before being returned to earth.
- Close encounters are events where persons witness UFOs, or purportedly meet and/or communicate with alien beings.
- Immanuel Velikovsky's proposals that ancient texts refer to the collision of astronomical bodies as in Worlds in Collision.
- Aromatherapy is the attempt to use oils for therapeutic purposes.
- Applied Kinesiology is pushing on muscles to find out what's wrong with someone.
- Aura Analysis is is the theory of diagnosis through visualization of human aura. This is closely connected to paranormal subjects.
- Chelation therapy is therapy that is used to flush heavy metals from the body, by encasing them in soluble molecules. While it does have valid uses, like treating lead-poisoning, some idiots claim that it will cure autism, likely from the idea that autism is caused by Mercury poisoning.
- A cleanse is taking substances claimed to remove "toxins" from the colon, liver, kidneys, lymphatic system, or other organs.
- Colonic hydrotherapy: "what's in your colon makes you sick" Really, what's in your colon makes me sick. They never quite got that right.

- Faith healing is the act of curing disease by such means as prayer and laying on of hands.
- Folk remedies are unproven medical practices deriving from pre-scientific sources or word of mouth.
- Hair Analysis is the theory of diagnosis through the levels of minerals in hair.
- Herbalism is healing by the ingestion of various plant preparations - teas, tinctures, poultices and the like. A few herbalist remedies have been shown through controlled clinical trials to have a physiological effect, but the majority are simply folk remedies.
- Homeopathy is a medical practice that claims to work by diluting various things in a solute. While modern pharmacology works similarly, and indeed likely owes much of its history to homeopathy, there is a patent denial of the dose response relationships that chemicals have with the body. Homeopathy is the exact opposite of modern pharmacology in the belief that things get more potent as they become more dilute. By current laws in most countries, in order for something to be labeled as "homeopathic" it must not contain anything but the solution that the treatment has been "distilled into". Homeopathy is entirely "natural", and "harmless", because it is in most cases simply water.
- Laetrile is a quack cancer treatment, outlawed in the U.S. because it breaks down into cyanide in the body.

- Reflexology deals with foot massages.
- Rolfing is the massage of the body's connective tissue, claimed to bring the posture back into correct alignment.
- Therapeutic touch is a form of vitalism where one passes one's hands over and around the body of a sick person so as to treat his/her illness.
- Pseudovitamins are substances not necessary in human nutrition but promoted as "vitamins" by those trying to market them.
- Wave genetics is cure of the disease by transferring the "image" of the DNA by means of sound, RF signals or lasers, often used in connection with other techniques.
 Other significant topics
The following are subjects regarded as pseudoscientific by notable skeptical bodies such as the Committee for Skeptical Inquiry (formerly CSICOP). Unless otherwise noted, the entries are referenced from The Skeptics Society's The Skeptic Encyclopedia of Pseudoscience Finally, some of these items are not considered pseudoscientific in and of themselves: only certain aspects, explanations, and/or applications of them. See an item's description text for more information on this.
- 2012 apocalypse We're all gonna die, and its gonna to happen in 2012, because the Mayans said so, and they would know.
- Anthroposophy is a philosophy which holds that that spirit world can be scientifically investigated.
- Anthroposophical medicine is the practice within the Anthroposophy belief system of various remedies intented for illnesses of a person's non-physical "soul."
- Attachment therapy is a psychotherapeutic treatment for aggressive, disobedient, and/or unaffectionate children (so-called attachment disorder). A minor version (relative to most other attachment therapies) involves the child being physically restrained by adults who then attempt to maintain prolonged eye contact. Perhaps the most extreme is "rebirthing," in which the child is wrapped tightly in a blanket and then made to simulate emergence from a birth canal. This is done by encouraging the child to struggle and pushing and squeezing him/her to mimic contractions.
- Ball lightning is a slow-moving, luminous sphere which is up to 30cm in diameter. While many scientists find the existence of these in nature at least minimally plausible, evidence of them are often unreliable; anecdotal reports and explanations for them have ranged from combusted hydrocarbon gas to "Will o' the wisp" creatures. Recently, however, different scientific research groups have reported the generation of ball-lightning-like plasma clouds in the laboratory. The study of ball lightning might therefore be shifting from pseudoscience towards protoscience.
- The Bermuda Triangle is a region of the Atlantic Ocean that lies between Bermuda, Puerto Rico, and (in its most popular version) Florida. Frequent disappearances and ship and aircraft disasters in this area have led to claims of paranormal phenomena and extraterrestrial attacks and abductions.
- Biorhythms are alleged periodic cycles of human physiology and behavior that govern physical, emotional, and intellectual well-being.

 Obscure and parody pseudoscience
The following are subjects that are sufficiently notable to warrant mention yet still too obscure for any mainstream group (of the sort cited above) to comment on them. They are nonetheless uncontroversially regarded as pseudoscientific: the only people insisting on the topics' scientific status appear to be their lone, respective proponents and, perhaps, a single digit quantity of devotees. Also included here are notable parodies of other pseudosciences and pseudoscientific concepts.
- Flying Spaghetti Monster is the deity of a parody religion founded by Oregon State University physics graduate Bobby Henderson. He created it in response to the 2005 evolution controversy sparked by Kansas's State Board of Education.
- Intelligent falling is a parody of intelligent design which attacks gravitation in the same way intelligent design attacks origin theories.
- Time Cube is a proposed theory of everything which holds that time is cubic. Its creator, Gene Ray, finds those who are ignorant of his theory to be "STUPID AND EVIL."
- The Magic 8 Ball knows! or does it?
- The Weekly World News was to pseudoscience what The Onion is to politics. Was it real or a spoof? You decide.
 Partial pseudoscience
Those subjects that may be genuine science, but many people take them to extremes that surpass the ability of current science to justify, or verify, their claims.
- Audio woo is making claims for the fidelity of sound reproduction that are unable to be objectively measured or substantiated.
- Chiropractic healing is healing by the cracking of one's back. As long as your problem only lies with your back, then a Chiropractor can be helpful. However, a lot of Chiropractors go way above "I can help with back-aches!" to "I can cure autism!"
- Cryptozoology is the study of animals whose existence is suspect. Famous examples include Bigfoot, the Loch Ness monster, and the goat-killing "Chupacabra."
- Exobiology is the study of non-terrestrial life forms. Currently this is a branch of science without a single thing to do except theorise.
- Forteanism is scepticism beyond the bounds of reason.
- Hypnosis is an extremely relaxed state in which a person is unusually responsive to suggestions made by the hypnotist. While hypnosis in some sense is almost universally regarded as real, explanations of the phenomenon invoking anything more than just an especially cooperative subject have far less scientific support. In addition, certain applications of hypnosis in psychotherapy, such as smoking cessation and self-esteem improvement, also lack empirical support.
- Psychoanalysis is a genuine area of study, but the field is historically and continues to be dominated by ideas lacking empirical support.
- Sigmund Freud and his ideas are the most prominent within psychoanalysis. Many of his ideas have since been refuted and lack empirical evidence but are still popular in psychoanalysis.
- Transactional Analysis is a non-Freudian approach to psychoanalysis popular during the late 20th century, also lacking in empirical support and best viewed as an arbitrary system of categorizing human interactions.
- Myers-Briggs Type Inventory claims to categorize human personality types.
