Different specimens of handwriting from a single individual are known to be highly consistent in both gross features and the smallest recognizable characteristics. It is this fact that allows handwriting to be known as a stable graphic expression of personality. Handwritings of individuals do vary from time to time, but typically much less than the superficial appearance would lead one to believe.
Changing the slant of writing from far right to more vertical will certainly affect the appearance, but the bulk of the writer’s personal characteristics remain unchanged. It is an absolute impossibility to fluently execute a script while omitting each of the writer’s habitual, identifying characteristics.
Suffice it to say that when a person’s handwriting “changes” for any reason up to and including a severe trauma, no more than two or three significant changes might be expected to occur and these changes can generally be attributed to a change of mood. Consistent change in handwriting, which is spontaneously executed, does not normally occur overnight. Changes generally occur over a period of transition of anywhere from a few weeks to a few months.
This includes the inclusion of new forms and the deletion of old forms. Handwriting reflects personality and also includes the more fleeting expressions of mood. Personality does not change overnight and neither does handwriting. Only when a significantly large number of features are divergent, and in sufficient degree, may one conclude that different personalities are represented in two different handwriting samples.
Each specimen of handwriting produced by Karen Kingston’s hand during her three-day exorcism was carefully analyzed and then diligently compared to every other specimen of her handwriting. Thus, not counting the specimens, which were treated as drawings (Wellesley, Chapter 9 and Mervin, Chapter 16), a total of twenty-eight unique pairwise comparisons were made. Fifty-eight factors were specifically assessed as to their presence or absence and, if present, the degree of intensity of each.
While we might expect as many as two or three significant differences due to variations in the writing of a single person, the writings of Karen Kingston showed no less than fourteen significant differences in terms of the assessed features when compared with one another. One pair of writings showed an incredible thirty major points of divergence; the average number of significant differences was in excess of twenty-one.
While it may be unimpressive to cite such large numbers as evidence that one person could not have written all of the Karen Kingston specimens, the fact is that one person did–Karen Kingston! The writings display varying emotional patterns, different levels of intellectual maturity, and different degrees of personality integration and adjustment. Several writings show equally disturbed personality characteristics, but the underlying dynamics of each writing is expressed in a Pattern that is unquestionably unique.
