Notes on the Lectures: Reality and Communication Scale
Scientiatry®
Hubbard plotted psychosis against his Reality and Communication scale. The numeric values correspond to his emotional tone scale. Note on that Tone 1 marks an artificial  personality with schizoid secrecy.
  REALITY AND COMMUNICATION SCALE

  The reality scale refers to the individual's hold on reality and his agreement with others on what reality is.  Reality breaks are actually disagreements on reality, usually resulting only from a different viewpoint and not from actual differences in reality itself. The communication scale refers to the individual's ability to communicate with other people.

Reality Communication
Tone 4 Search for different viewpoints and changes in reality in order to broaden own reality — complete flexibility in understanding, relating and evaluating different realities

Ability to communicate completely, withholding nothing; ability to create and construct through conversation
3.5 Ability to understand, relate and evaluate reality, regardless of change or difference in viewpoint, moderate flexibility in realities brought to view without eager searchfor new ones

Swift exchange of deep-seated, deeply felt beliefs and ideas
Attempts to reconcile own reality with conflicting reality—limited flexibility

Tentative expression of limited number of personal beliefs and ideas
Tone 3 Awareness of possible validity of different reality (viewpoint without relating it to own reality)

Casual exchange of superficial chatter
2.5 Indifference to conflicting reality—"Maybe —who cares?" attitude Indifference to communication of others—"Let's not argue about it" attitude—dismissal of communication—if toward environment, not trying to get perceptics clear

Refusal to match two realities, rejection of conflicting reality "So what?" attitude Refusal to accept communication of other person (or environment) — turning to other sources of communication

Tone 2 Verbal doubt — defence of own reality, attempts to undermine others

Indirect pot-shooting, nagging, nasty cracks, invalidating other person or situation
1.5 Destruction of opposing reality, wrecking or changing it, knocking out props from other person's reality — "You're wrong!" attitude. If reality is environmental, destruction is accomplished only through change

Shutting off other person's communication, destruction of it — "Shut up!" "Drop it!"
Doubt of opposing reality, non-verbal disbelief, refusal to accept disbelief, refusal to accept conflicting reality without trying to fight back

Stubborn silence, sulking, refusal to communicate further, rejection of attempted communication by others
Tone 1 Doubt of own reality — insecurity; attempts to gain reassurance; if reality is environmental — appeasement of gods or elements Lying to avoid real communication; can take the form of pretended agreement, flattery or verbal appeasements; or simply a false picture of person's feelings and ideas; false facade, articial personality

0.5 Shame, anxiety, strong doubt of own reality with consequent inability to act within it, must be told what to do if person is to act at all, afraid to act himself since he has no way to assess consequences Evasiveness to avoid communication; hiding person's own thoughts and feelings superficial communication built on accepted standards without relation to person's real feelings; or shizoid secrecy

Complete withdrawal from conflicting reality; refusal to test own reality against conflicting one; Locked in own rigid reality — psychotic

Inability to communicate, completely unresponsive
