Editing Personal construct theory (section)

== Principles ==
A main tenet of PCP theory is that a person's unique psychological processes are channeled by the way they anticipate events. Kelly believed that anticipation and prediction are the main drivers of our mind. "Every man is, in his own particular way, a scientist", said Kelly: people are constantly building up and refining theories and models about how the world works so that they can anticipate future events. People start doing this at birth (for example, a child discovers that if they start to cry, their mother will come to them) and continue refining their theories as they grow up.

Kelly proposed that every construct is bipolar, specifying how two things are similar to each other (lying on the same pole) and different from a third thing, and they can be expanded with new ideas. (More recent researchers have suggested that constructs need not be bipolar.<ref>For example: {{harvnb|Riemann|1990}}; {{harvnb|Yorke|2001}}</ref>) People build theories—often stereotypes—about other people and also try to control them or impose on others their own theories so as to be better able to predict others' actions. All these theories are built up from a system of constructs. A construct has two extreme points, such as "happy–sad," and people tend to place items at either extreme or at some point in between. People's minds, said Kelly, are filled up with these constructs at a low level of awareness.

A given person, set of persons, any event, or circumstance can be characterized fairly precisely by the set of constructs applied to it and by the position of the thing within the range of each construct. For example, Fred may feel as though he is not happy or sad (an example of a construct); he feels as though he is between the two. However, he feels he is more clever than he is stupid (another example of a construct).  A baby may have a preverbal construct of what behaviors may cause their mother to come to them. Constructs can be applied to anything people put their attention to, and constructs also strongly influence what people fix their attention on. People can construe reality by constructing different constructs. Hence, determining a person's system of constructs would go a long way towards understanding them, especially the person's essential constructs that represent their very strong and unchangeable beliefs and their self-construal.

Kelly did not use the concept of [[the unconscious]]; instead, he proposed the notion of "levels of awareness" to explain why people did what they did.{{sfn|Fransella|2005|p=11}} He identified "construing" as the highest level and "preverbal" as the lowest level of awareness.{{sfn|Fransella|2005|p=11}}

Some psychologists have suggested that PCT is not a psychological theory but a [[metatheory]] because it is a theory about theories.{{sfn|Fransella|2003|p=8}}
