Folk science is a term used in psychology and anthropology to describe systems of knowledge about the workings of the natural world that are not based on the scientific method, often relying instead on either intuition or empiricism in its crudest form. Pseudoscience is often based on some sort of folk science and because many scientific findings are counter-intuitive, they may be difficult to grasp, rendered into a folk science form, or flat-out denied.
 Folk biology and folk taxonomy
Folk biology refers to common observations made by people about living organisms and how they interact with the natural world. Organisms are classified by a system of folk taxonomy and all known languages appear to have five (or possibly six) levels of taxa arranged in a hierarchical system (unique beginner, life form, generic, specific, varietal). Creationism and biological determinism are often based on folk scientific interpretations of real biology.
 Folk physics
A common misconception in folk physics (sometimes called "naive physics") is the idea that moving objects have some kind of "impetus," a sort of naive form of momentum in which an object has an internal force moving it forward. Thus, moving objects are conceived of in a pre-Newtonian framework in which objects in motion are not stopped or slowed by an external force, but their internal impetus is "spent" and they stop moving. The idea of a "centrifugal force" in which a supposedly "true" force pushes an object traveling in a circle outward rather than the object's movement being a product of inertia is another example of folk physics.
 Folk psychology
Many commonly held ideas about the mind, such as a "ghost in the machine"-style free will and mind-body dualism, are now considered to be folk psychology (sometimes "common sense" psychology), based on our evolved cognitive biases. The idea of a soul or some kind of disembodied consciousness lies at the heart of various pseudo-psychological theories, e.g. non-materialist neuroscience. There is some debate in theory and philosophy of mind as to whether folk psychology holds some use for the psychological sciences or should be totally discarded.
