Origins

A lineage of trusted digital systems

The lineage runs through interactive computing built for the highest-stakes work — systems trusted because the evidence said so, not because of who built them. The principle held at every step, across every field the Association now covers: a system earns trust through evidence and validation, not authority alone.

The largest yet most neglected healthcare resource, worldwide, is the patient.

The lineage

Sixty years of earning trust through evidence

From the LINC — one of the first interactive personal computers — through procedurally invariant systems engineered at Wisconsin and validated at national scale, one principle holds: a system is trustworthy only when the evidence says so.

  1. 1962

    The first interactive personal computer

    The LINC (Laboratory Instrument Computer), built by Wesley Clark and Charles Molnar, is widely recognized as the first interactive personal computer. NIH-funded and released as a public-domain design, it put real, reliable computing directly into the hands of the people doing the work - the root of a tradition that trusts the user and the source.
  2. 1965

    Computing changes how evidence is captured

    At the University of Wisconsin, Warner Slack builds the first interactive computer interview, founded on a simple conviction: the person closest to the facts is the most reliable source. The 1966 report in the New England Journal of Medicine found that the computer-administered interview produced more complete and accurate records than the human-run process — an early demonstration that well-designed interactive systems outperform ad-hoc human process. Trustworthy systems begin by capturing evidence directly at its source.
  3. 1973

    Procedurally invariant computing at Wisconsin

    John Greist and colleagues at the University of Wisconsin build a pioneering interactive assessment system running on a LINC computer. It asked every person the same questions in the same order — procedurally invariant where human process is not — and the structured, model-driven output was more consistent and accurate than unaided judgment. The principle was computing: remove the variability, trust the evidence, prove it holds.
  4. 1979

    A line to Epic Systems

    In a Madison basement, John Greist helps found Human Services Computing - with Judith Faulkner, who had studied computing in medicine under Warner Slack, and several others. Renamed Epic Systems in 1983, it grows into one of the most widely used health-record systems in the world; Greist served on its board until 1983. The Wisconsin lineage that began with a patient interview runs directly into modern health computing.
  5. 1997

    Digital systems enter high-evidence domains

    By Meret’s account, John Greist’s team builds the first computerized patient assessment used in a rigorous clinical trial — carrying interactive digital systems into some of the most evidence-demanding settings any software enters. Every question asked the same way, every answer recorded the same way, every time.
  6. 2011

    A validated gold standard

    Kelly Posner and colleagues publish the validation of the Columbia-Suicide Severity Rating Scale across multiple studies, turning expert judgment into a standardized, reproducible instrument - the discipline of measuring the same thing the same way, and proving it.
  7. 2012

    Evidence becomes the expectation

    U.S. regulatory guidance establishes prospective, standardized assessment as the norm in clinical trials - shaped in part by Thomas Laughren, a coauthor of the 1973 Wisconsin study who had become a director at the FDA. Within four decades, a Wisconsin research idea had become a regulatory expectation.
  8. 2014

    A digital instrument validated at scale

    The electronic assessment system built in Madison is validated across more than 74,000 administrations in 33 independent studies — showing that a well-designed digital instrument is consistent and reliable far beyond any single site or operator. Reliability, consistency, and independent validation become the working definition of a system worth trusting.

    Meret Solutions

    Meret Solutions is founded in Madison, Wisconsin (per the company’s record) to extend more than fifty years of computer-interviewing practice into clinical and educational settings, with its assessment systems and the eC-SSRS at its core.

    The Meret Association

    The Meret Association for Trusted Digital Systems is established with the support of Meret Solutions to recognize, across every discipline, the engineers and researchers who build digital systems the world can rely on. The Association governs its recognition independently.
The through-line

What the lineage teaches

Across six decades and many disciplines, the same four principles separate a system the world can trust from one it merely tolerates. They are the standard the Association now applies, in every field.

Consistency

A trustworthy system treats every case the same way, every time. The 1973 Wisconsin interview asked each person identical questions in identical order - removing the variability that creeps into any human-run process.

Evidence at the source

Capture data directly and faithfully where it originates. From the first patient interview onward, this lineage trusted the source and recorded it without distortion.

Validation over assertion

A system earns trust only when independent evidence says so - not because of who built it. Every step here was published, scrutinized, and validated before it was relied upon.

Reproducibility

Results that hold across people, places, and time. Standardized, validated instruments return the same answer regardless of who administers them - the foundation of a credential the world can rely on.

The founders

The people behind the Association

The Meret Association was founded with the support of Meret Solutions. Its recognition of Fellows is governed independently by the Selection Committee.

Portrait of John Greist
Founder

John GreistMD

Co-Founder and Chief Medical Officer, Meret Solutions

John Greist is one of the pioneers of computerized medicine. In 1973, at the University of Wisconsin, he and his colleagues built a pioneering computer interview for risk prediction - work that helped establish a principle the Association now carries into every field: that a system earns trust through evidence, validation, and candor, not authority alone.

He is Emeritus Professor of Psychiatry at the University of Wisconsin School of Medicine and Public Health, and Research Professor (Volunteer) in the Department of Psychiatry and Behavioral Sciences at the University of Kansas School of Medicine-Wichita. His university and publisher biographies credit him with more than 300 professional journal articles, book chapters, and books.

His research helped pioneer computer-administered assessment and therapy across four decades: a comparison of computer- and interviewer-administered diagnostic interviews (1987); one of the first randomized trials of computer-administered cognitive behavior therapy for depression (1990); a computer-administered version of the Yale-Brown Obsessive Compulsive Scale; interactive-voice-response administration of standard rating scales at scale; and - most distinctively - computer-guided behavior therapy for obsessive-compulsive disorder, evaluated in a multi-site randomized trial (2002). A recurring finding across this work, and across computerized interviewing since the 1960s, is that people often answer a computer more candidly than a clinician.

In 1979 he helped found Human Services Computing - with Judith Faulkner, who had studied computing in medicine under Warner Slack, and several others - the Madison company renamed Epic Systems in 1983; he served on its board until 1983. He also founded PRN Systems and Healthcare Technology Systems, and serves as Chairman of the Board and Chief Medical Officer of Meret Solutions, the Association’s founding sponsor.
