The University of Utah Connection

The scientific foundations of Axciton's technology trace directly to the pioneering research of Dr. David C. Raskin and Dr. John C. Kircher at the University of Utah. Raskin was a professor of psychology and well-known psychophysiologist, while Kircher arrived at the university as a graduate student in 1977 and was tasked with programming a microcomputer to measure psychophysiological reactions to polygraph test questions [10]Verified Your Lying Eyes — University of Utah Interview with John Kircher
Confirms Kircher and Raskin introduced first computer-assisted polygraph in 1986 and first fully automated system in 1991; Kircher arrived at Utah in 1977.

Kircher spent his early years in graduate school teaching himself computer programming. He ultimately created algorithms for extracting diagnostic information from polygraph recordings and combining them in a statistically optimal manner to determine whether an examinee was truthful or deceptive [10]Verified Your Lying Eyes — University of Utah Interview with John Kircher
Confirms Kircher and Raskin introduced first computer-assisted polygraph in 1986 and first fully automated system in 1991; Kircher arrived at Utah in 1977. In their landmark 1988 study, Kircher and Raskin compared human examiner scoring with computerized analysis and found that computerized evaluations achieved accuracy of at least 90%, equaling or exceeding human scorers [11]Verified Human Versus Computerized Evaluations of Polygraph Data in a Laboratory Setting
Compared human examiner scoring with computerized analysis. Found computerized evaluations achieved accuracy of at least 90%, equaling or exceeding human scorers. This research demonstrated the feasibility of automated polygraph interpretation.

Together, Kircher and Raskin developed the Computer Assisted Polygraph System (CAPS) in 1988, which incorporated the first algorithm to be used for evaluating physiological data collected for diagnostic purposes [12]Verified History of Polygraph — Ohio Polygraph Services
Confirms Raskin and Kircher developed CAPS in 1988; polygraph entered computer age in 1992; PolyScore completed in 1993.

The Employee Polygraph Protection Act and Market Transformation

The late 1980s represented a period of profound upheaval for the polygraph industry. The Employee Polygraph Protection Act (EPPA) became law on June 27, 1988 (effective December 27, 1988), prohibiting most private employers from using polygraph tests for pre-employment screening or during employment [13]Verified Employee Polygraph Protection Act — Wikipedia
Confirms EPPA became law in 1988, prevents most private employers from using polygraph tests, exempts federal/state/local government. The law eliminated approximately 85% of the polygraph tests then being administered [14]Verified Employee Polygraph Protection Act of 1988: Background and Implications
Confirms EPPA eliminated 85% of polygraph tests then being administered, devastating the private-sector testing market virtually overnight.

The EPPA's impact on the equipment manufacturing landscape was seismic. Before the law, the majority of polygraph examinations were conducted for private employers screening job applicants and investigating workplace theft. With this market eliminated, federal, state, and local government agencies — exempted from the EPPA [13]Verified Employee Polygraph Protection Act — Wikipedia
Confirms EPPA became law in 1988, prevents most private employers from using polygraph tests, exempts federal/state/local government — became the primary customers for polygraph equipment manufacturers. Security firms, pharmaceutical companies, and employers investigating specific incidents of economic loss retained limited exemptions [15]Verified H.R.1212 — Employee Polygraph Protection Act of 1988
Confirms EPPA exemptions for federal, state, local governments and certain security/pharmaceutical employers, but the core private-sector demand had evaporated.

Paradoxically, this market contraction created an opportunity for Axciton. Government agencies demanded higher accuracy, better data management, and more sophisticated analysis tools than analog instruments could provide. The shift toward government and law enforcement as primary customers aligned perfectly with Axciton's emerging computerized technology, which offered the precision, reproducibility, and data storage capabilities that government procurement officers increasingly required.

The Analog Era and Pressure for Change

Throughout the 1980s, polygraph examinations still relied on analog instruments — mechanical devices using streaming graph paper, ink pens, and physical pen adjustments to record physiological data [16]Verified Polygraph Technology — Office of Justice Programs
Confirms Axciton claims up to 95% accuracy when PolyScore software is used; describes virtual graph eliminating mechanical issues. These instruments, while effective in skilled hands, were prone to mechanical glitches, ink clogging, and produced records that were difficult to store, share, or systematically analyze.

The U.S. Congress Office of Technology Assessment (OTA) had published a significant report in November 1983 examining the scientific validity of polygraph testing. The OTA found that the control question technique had some validity in criminal investigations, but the evidence was insufficient for personnel security screening applications. This report intensified the call for more objective, standardized, and scientifically defensible polygraph methods — precisely the capabilities that computerization promised.

Meanwhile, researchers at Northwestern University had proposed digital analysis of polygraph data as early as 1974, when Matthew Petrovic of the Northwestern University Biomedical Laboratory met with John Reid and proposed the development of artificial intelligence for analyzing polygraph tracings [17]Verified Polygraph Test — ScienceDirect Topics Overview
