Perry Theory

William Perry's Scheme of Intellectual and Ethical Development (1970) specifies a sequence of stages of development of an individual's epistemological and ethical position.[1] It is a structural theory, providing a framework into which different philosophies and sets of values can be fitted. Perry's Theoretical framework has been verified and expanded by later researchers.[2] A brief summary of Perry's original theory is as follows.[3]

Dualism

Simple dualism is a bifurcated structuring of the world between good and bad, right and wrong, us and them. Dualistic views are characterised by simple dichotomies, for example seeing the world as liberal vs. conservative. There is a heavy reliance on absolutes and authority[4] as the sources of truth, values and control. Knowledge is rarely justified rationally, but rather by reference to an authority. Dualism implies that actions are either right or wrong.

Multiplicity

This is a more complex structuring where there is a plurality of answers, and points of view. This is perceived as an aggregate of discretes without any internal structure or external relation. Viewpoints given are often 'Anyone has a right to his or her opinion', with the implication that no judgement can be made about the quality or validity of the opinion. An example of this is the suggestion that multiple perspectives on the origin of life should be taught in schools, on the grounds that intelligent design, young Earth creationism and evolution are all theories, and therefore equal in status.

Relativism

This is a more sophisticated and complex position, which recognizes a plurality of points of view, interpretations, frames of reference and value systems, and admits to the fact that knowledge and ethical positions are contingent on context, and judgements can be made through analysis, comparison and evaluation. Epistemologically, Relativism requires that knowledge, answers and choices are dependent upon particular features of a context, and are evaluated or justified through principled rule-based systems. A good example of relativism is in the workings of the judicial system. Although the killing of an individual is judged by society to be wrong, there are a number different ways in which that killing can be classified, and when sentencing, contextual details of the particular case are crucial in determining an appropriate custodial or other sentence.

Educators' perspectives

Perry theory is seen by many educationalists as a developmental spectrum, and that a move from simple dualism to relativism will benefit the student's intellectual growth and development; this can be done by challenging a student's dualistic or multiplistic positions.[5] A 2005 study by Steven Verhey attempted to move students from simple dualistic positions by asking them to read parts of an ID-friendly, antievolution text, as well as an online refutation of the text and parts of a book presenting evidence for evolution.[6]

gollark: I would really have recommended putting together a parts list *before* buying things.
gollark: Yes.
gollark: PCPartPicker is pretty good for checking compatibility of stuff.
gollark: If you're buying a Ryzen 5 2600, then you need DDR4 DIMMs, and higher-speed (>=2933MT/s) is recommended.
gollark: That might be hard since I don't really have electronic components at home, but I'm sure i have an LED or something.
