Personal construct psychology Guide, Meaning , Facts, Information and Description
Personal Construct Psychology (PCP) is a theory of personality developed by American psychologist George Kelly in the 1950's. From the theory, Kelly derived a psychotherapy approach and also a technique called The Repertory Grid Interview that helped his patients to uncover their own "constructs" (defined later) with minimal intervention or interpretation by the therapist. The Repertory Grid was later adapted for various uses within organizations, including decision-making and interpretation of other people's world-views.

The main tenet of PCP theory is the following:
A person's unique psychological processes are channelized by the way he anticipates events
Kelly believed that anticipation and prediction are the main drivers of our mind. "Man is a scientist", said Kelly, in that he is always building up and refining theories and models about how the world works so that he can anticipate events. We start on this since we are born (mmm... if I cry mommy will come, discovers Baby...) and keep up refining our theories as we grow up. We build theories -often, stereotypes- about other people and also try to control them or impose on others our own theories so that we are better able to predict their actions. We crave certainty.
All these theories are built up from a system of constructs. A construct has two extreme points, such as "happy-sad" and we tend to place people at either extreme or at some point in between. Our mind, said Kelly, is filled up with these constructs, many of them unconscious. A given person or set of persons or any event or circumstance can be characterized fairly precisely by the set of constructs we apply to it and the position of the thing within the range of each construct. So Fred for instance may be just half between happy and sad (one construct) and definitively clever rather than stupid (another construct). The baby above may have an unconscious construct "Comes... doesn't come when I cry".
Constructs are applied to anything we put our attention to, including ourselves, and also strongly influence what we fix our attention on. We construe reality constructing constructs. Hence, determining a person's system of constructs would go a long way towards understanding him, specially the person's essential constructs that represent very strong and unchangeable beliefs; and also the constructs a person applies to him/herself.
Kelly believed in a non-invasive approach to psychotherapy. Rather than having the therapist interpret the person’s psyche, which would amount to imposing the doctor’s constructs on the patient, the therapist should just act as a facilitator of the patient finding his own constructs. The patient’s behavior is then mainly explained as ways to selectively observe the world, act upon it and update the construct system in such a way as to increase predictability. To help the patient find his constructs, Kelly developed the Repertory Grid Interview technique.
To build a Repertory Grid (a sort of matrix) for a patient, Kelly would first ask the patient to select about seven elements whose nature might depend on whatever the patient or therapist are trying to discover. For instance, “Two specific friends, two work-mates, two people you dislike, your mother and yourself”, or something of that sort. Then, three of the elements would be selected at random, and then the therapist would ask:"In relation to… (whatever is of interest), in which way two of these people are alike but different from the third"? The answer is sure to indicate one of the extreme points of one of the patient’s constructs. He might say for instance that Fred and Sarah are very communicative whereas John isn’t. Further questioning would reveal the other end of the construct (say, introvert) and the positions of the three characters between extremes. Repeating the procedure with different sets of three elements ends up revealing several constructs the patient might not have been fully aware of.
The Repertory Grid itself is a matrix where the rows represent constructs found, the columns represent the elements, and cells indicate with a number the position of each element within each construct. There is software available to produce several reports and graphs from these Grids.
PCP was never very popular in the US; in England and Canada however, there are several followers both of the therapy approach and of the applications of the Grid to other areas. For instance, in making a purchasing decision among several candidate products, the Grid could be used to extract the main constructs which one tends to apply to the products. Several other applications to decision-making situations have been developed, as well as software to apply the grid interactively.

Summary of Kelly’s work, including the theory and the repertory grid. The Geometry mentioned in the title results when constructs are mapped as straight lines on a plane, where similar constructs get clustered. Elements are represented as points close to the constructs that construe them.
