20 Reasons Why...

2009  ​After a forensic case review of a questionable homicide/suicide, Dr. Doscher began researching  various methods of deception detection.
2012  ​No measurable connection existed between nonverbal and verbal deceptive cues.
2015 -18  ​Graphological field studies were launched.  More than 1100 written statements were analyzed.
2016  ​Dr. Doscher created a psychodiagnostic tool to differentiate truthful and deceptive handwritten cues, which can be effectively utilized by law enforcement, attorneys, forensic interviewers, human resource managers, loss-prevention investigators,therapists, social workers, private investigators, and private security personnel.
June 2017 ​ Doscher Graphological Analysis, LLC was formed to provide supplemental tangible evidence for interviews, interrogations, and polygraph examinations, further augmenting ​criminal and civil investigations.

Doscher Graphological Analysis (DGA) offers a scientific approach to deception detection during pre-employment screening, interrogations and interviews.

The DGA method confirms the presence of nonverbal and verbal behavioral cues.

Because human behavior is unique, the DGA method's approach to deception detection is subject-specific; no generalizations from previous correlative studies are considered.

The research based method is an indirect quantitative approach to quantifying psychological cues.
