Language is our most fundamental model-making tool - the symbolic representation of experience. In building up their personalised models of the world, people use three basic processes - generalisation, deletion and distortion.
Generalisation - inferring from the particular to the general; assuming one example stands for all others of its class, Generalizations lead to false assumptions.
Deletion - oversimplifying; omitting important specific details. Deletions lead to 'blind spots'.
Distortion - changing what is real into what we wish was real. Distortions lead to misrepresentations, misunderstandings and fantasies.
Language also uses the processes of generalisation, deletion and distortion. What we say out loud is a short `form - a 'surface structure' - of a much more complex set of perceptions and beliefs - the 'deep structure'.
The 'Meta-Model' is a tool-kit for retrieving deep structure from surface structure. It also suggests responses for re-structuring the various types of generalizations, deletions and distortions.
Gathering Information - uncovering and exploring specific portions of the speaker's experience which are missing from the surface structure or distorted within it.
Expanding Limits - defining and expanding the boundaries and limitations of the speaker's assumptive world, thereby generating more perceptive and behavioural choices.
Changing meanings - reworking the meaning and significance of the speaker's relationship with himself, those around him, and with the world in general.
