Pseudociência by David Marçal
5.0

Definition
Any methods, theories and systems, such as astrology, psychokinesis or clairvoyance, are considered to have no scientific basis.

Pseudoscience describes any belief system or methodology that tries to gain legitimacy using science traps but does not comply with the rigorous methods and standards of evidence that are the hallmarks of natural science.
Promoters of pseudoscience often adopt the science vocabulary, describing conjectures as hypotheses, theories or laws, providing "evidence" of the testimony of observation and "experts", or even developing what appear to be mathematical models of their ideas.
However, in pseudoscience, there is no honest attempt to follow the scientific method, provide falsifiable predictions or develop double-blind experiments.
Although pseudoscience has designing to appear scientific, it lacks all the substance of science.

What is
A pseudoscience is a belief or process that disguises itself as science in an attempt to claim a legitimacy that it would not otherwise be able to achieve on its terms; It has often known as a marginal or alternative science.
The most important of its defects is generally the lack of carefully controlled and interpreted experiments that provide the foundation for the natural sciences and contribute to its advancement.

Concept
Pseudoscience includes beliefs, theories and practices that were or are considered scientific but have no scientific basis. This fact could mean that they have been scientifically disproving, cannot be tested or lack evidence to support them.

What it consists of
Pseudoscience consists of statements, beliefs or practices presented as scientifically plausible but which are not justified by the scientific method.
A topic, practice or body of knowledge can reasonably consider pseudoscientific when presented as consistent with the standards of scientific research but demonstrably fails to meet those standards.

Pseudoscience is often characterising by the following:
Contradictory, exaggerated or unlikely claims;
Confidence in confirmation bias rather than rigorous attempts at rebuttal;
There is a lack of openness for evaluation by other specialists; and an absence of systematic practices when developing theories.
The term pseudoscience will be pejorative because it suggests something presented as inaccurate or even misleading science.
Consequently, those termed as practising or advocating pseudoscience often dispute characterisation.

The distinction between science and pseudoscience has philosophical and scientific implications.
Differentiating science from pseudoscience has practical implications for health care, expert testimony, environmental policies and science education.

The distinction between scientific facts and theories of pseudoscientific beliefs, such as those found in astrology, alchemy, medical quackery, occult beliefs and creation science combined with scientific concepts, is part of science education and scientific literacy.
