Professors John C. Kircher (left) and David C. Raskin (right) are internationally-known and highly respected scientists in the polygraph community. They frequently consult and lecture on this subject, as well as provide guidance to the polygraph community, government agencies, legislatures, and the courts.

They first published research on polygraph technology in the 1970s and then spent 10 years developing the software and hardware for the world’s first computerized polygraph system, which they marketed in 1991. They recognized the need to find new lie detection methods that could complement the polygraph.

In 2002, John Kircher and his colleague, Doug Hacker (right), an educational psychologist with expertise in the psychology of reading, were driving to Seattle to climb Mt. Rainier. En route, they wondered if changes in eye movements and pupil size while reading and answering questions about a crime would reveal deception. They asked themselves, “Would changes in cognitive load affect the eye in such a way that we can capture those changes and be as accurate as the polygraph in predicting whether or not someone is being deceptive?”

Thus the idea for an ocular-motor deception (ODT) test was born — later to be branded as EyeDetect.

In 2003, Professors Kircher and Hacker formed a science team that included cognitive scientists Anne Cook (left) and Dan Woltz (right). They began working together to produce and validate an ODT solution.

In 2006, the Osher Dissertation documented the first lab study that demonstrated the effectiveness of the ODT. A second formal scientific study in 2008 confirmed the effectiveness of the ODT technology, and its results were published in the Webb Dissertation in August of that year.

In October 2009, Credibility Assessment Technologies LLC (CAT) was formed to begin laying the groundwork for bringing this technology to the market.

On December 12, 2013, the company was officially renamed Converus, Inc. The name Converus is derived from two Latin words: con (meaning “with”) and verus (meaning “truth”).

After 10 years of the Converus science team fine-tuning EyeDetect, this innovative technology has emerged as a viable, complementary method to the polygraph for business and government applications. Converus’ vision is to provide trustworthy, innovative solutions for the deception detection industry.
