Graphology

Although proponents point to positive testimonials as anecdotal evidence of its utility for personality evaluation, these claims have not been supported by scientific studies.

[10][11] In American graphology, Camillo Baldi's Trattato come da una lettera missiva si conoscano la natura e qualità dello scrittore from 1622 is considered to be the first book.

In Germany during the 1920s, Ludwig Klages founded and published his findings in Zeitschrift für Menschenkunde (Journal for the Study of Mankind).

[21][22] Thea Stein Lewinson and J. Zubin modified Klage's ideas, based upon their experience working for the U.S. government, publishing their method in 1942.

While hard data is lacking, anecdotal accounts indicate that 10% of the members of International Graphoanalysis Society (IGAS) were expelled between 1970 and 1980.

[24] Regarding a proposed correlation between biological sex and handwriting style, a paper published by James Hartley in 1989 concluded that there was some evidence in support of this hypothesis.

In his May 21, 2013 Skeptoid podcast episode titled "All About Graphology", scientific skeptic author Brian Dunning reports:[6]In his book The Write Stuff, Barry Beyerstein summarized the work of Geoffrey Dean, who performed probably the most extensive literature survey of graphology ever done.

In fact, no graphologist of any kind was able to show reliably better performance than untrained amateurs making guesses from the same materials.

Dunning concludes:[6]Other divining techniques like iridology, phrenology, palmistry, and astrology also have differing schools of thought, require years of training, offer expensive certifications, and fail just as soundly when put to a scientific controlled test.

No amount of sciencey sounding language can make up for a technique failing when put to a scientifically controlled test.Although graphology had some support in the scientific community before the mid-twentieth century, more recent research rejects the validity of graphology as a tool to assess personality and job performance.

Recent studies testing the validity of using handwriting for predicting personality traits and job performance have been consistently negative.

[31] A broad literature screen by King and Koehler confirmed that dozens of studies showing the geometric aspects of graphology (slant, slope, etc.)

[43] The letter also said that there was no judicial guidance on "whether a policy of excluding applicants based upon their handwriting has an adverse impact on a protected group" under the ADA, ADEA, or Title VII of the Civil Rights Act of 1964.

[52][failed verification] A graphological report is meant to be used in conjunction with other tools, such as comprehensive background checks, practical demonstration or record of work skills.

Research studies have been conducted in which a detailed examination of handwriting factors, particularly timing, fluidity, and consistency of size, form, speed, and pressure are considered in the process of evaluating patients and their response to pharmacological therapeutic agents.

[62] The study of these phenomena is a by-product of researchers investigating motor control processes and the interaction of nervous, anatomical, and biomechanical systems of the body.

[64] The purported therapy consists of a series of exercises similar to those taught in basic calligraphy courses, sometimes in conjunction with music or positive self-talk.
