DOUGLAS GRIFFITH
A life of inquiry, reflection, and humane curiosity.
Douglas Griffith devoted his life to understanding how people remember, learn, make decisions, use technology, and understand one another. For Doug, thinking deeply was never separate from living thoughtfully.
His Story
A Mind Shaped by Inquiry
Douglas “Doug” Griffith was a psychologist, research scientist, writer, and lifelong student of the human mind. His professional work explored how people remember, learn, make decisions, interact with technology, and relate to one another. The same curiosity shaped his life beyond the laboratory. He paid attention. He questioned assumptions. And he remained willing to reconsider his own conclusions when better evidence appeared.
When Kisoon speaks about what distinguished Doug, she often returns to the way he moved through the world. He was deliberate and attentive in his interactions with others. His intelligence did not make him formal or remote; he could pursue difficult ideas with seriousness while remaining unassuming, approachable, and quietly funny.
Doug was born on May 6, 1946, in Paterson, New Jersey. He earned a bachelor’s degree with distinction in psychology from The Ohio State University in 1967. After serving in the U.S. Army from 1968 to 1970, he continued his studies at the University of Utah, earning a master’s degree in psychology in 1972 and a doctorate in experimental psychology in 1974. His graduate work centered on human information processing, learning, and cognition—questions that would remain with him throughout his career.
While serving in South Korea, Doug volunteered as an English instructor. It was there that he and Kisoon met, beginning the relationship that would become one of the defining commitments of his life. Their meeting also reflected something characteristic of Doug: he did not move through places or relationships casually. He approached them with curiosity, attention, and purpose.
Research in Service of Human Understanding
Doug began his professional research career at the U.S. Army Research Institute for the Behavioral and Social Sciences, where he studied learning, memory, attention, mental imagery, human performance, and the ways people process information. His work addressed practical questions of training and decision-making while remaining grounded in a deeper interest in how the mind works.
His career later expanded into applied cognitive psychology and human factors. Through the Environmental Research Institute of Michigan, Veridian, and General Dynamics, he worked on problems involving mental workload, cognitive task analysis, imagery and information systems, training, accessibility, and human-computer interaction. He also contributed to research intended to make computers more useful to people who were blind or visually impaired.
One idea that became especially important in Doug’s later work was what he called “neo-symbiosis”—the idea that people and computers could be designed to complement one another, each contributing particular strengths while the human remained in the guiding role. It reflected a concern that ran through much of his career: technology mattered most when it served human understanding and human needs.
Doug’s professional contributions were recognized within his field. He served as president of the American Psychological Association’s Division 21, devoted to applied experimental and engineering psychology, and as president of the Potomac Chapter of the Human Factors and Ergonomics Society. Yet titles and recognition were never the point. Across very different settings, his central question remained remarkably consistent: how could a clearer understanding of the mind help people learn more effectively, make better decisions, work more successfully, and use technology more thoughtfully?
“He was both a scientist and a philosopher—someone who created art with his ideas.”
— Kisoon Griffith
A Distinctive Way of Moving Through the World
Doug’s writings reveal a thinker who resisted easy conclusions about people. He examined evidence that challenged cynical accounts of human nature, including research on cooperation, altruism, expectations, aging, power, and the effects of social circumstances. He did not confuse skepticism with distrust. Even when he held a definite view, he treated knowledge as something that could be revised when better evidence appeared.
That habit of mind stretched across decades. His earliest academic work explored learning, memory, recall, and human information processing; later, his interests expanded into cognition, technology, aging, human behavior, society, and the relationship between people and increasingly sophisticated computer systems. The subjects changed, but the underlying impulse remained the same: understand carefully before concluding.
These questions did not remain confined to his desk. Doug enjoyed gathering with friends and colleagues whose interests overlapped with his own, and conversations could continue at length as they considered subjects that later appeared in his blog: memory, consciousness, human behavior, society, and the possibilities opened by new research. At quieter moments there was jazz, a science-fiction film, travel, or an ordinary outing with Kisoon.
That range was part of who he was. The same man who could become deeply absorbed in a question about the mind also valued the familiar pleasures of conversation, companionship, humor, and daily life. Intellectual curiosity was not something Doug switched on for his work; it was simply one of the ways he experienced the world.
Doug and Kisoon
Doug and Kisoon’s life together began in South Korea and continued through decades in Virginia. His devotion to research existed alongside the life they built as husband and wife: a home, enduring friendships, travel, shared interests, long conversations, and the routines that gradually become the substance of a life together. Since Doug’s death, Kisoon has spoken of missing not only the person with whom she could discuss life’s largest questions, but also the companion beside her through its ordinary hours.
Their creative work took different forms. Doug worked through research, language, questions, and ideas; Kisoon through color, form, and visual imagination. Doug responded to her independence as an artist and encouraged her work without trying to direct it. Kisoon, in turn, recognized the creativity within his thinking. When she said that he “created art with his ideas,” she captured something essential about the man she knew: for Doug, thinking itself could be a creative act.

Seen Through Kisoon’s Eyes
In the winter and spring of 2026, following Doug’s death in December 2025, Kisoon painted two portraits of him, both titled Douglas Griffith. Together, they offer two deeply personal views of the person she knew so well.
In one portrait, Doug appears quiet and contemplative, resting his chin in his hand and looking outward with a thoughtful, calm expression. In the larger work, Kisoon surrounds him with elements of his intellectual and personal world—books, papers, flowers, and familiar companions. Lines radiate outward from Doug like wires carrying a signal, expressing the idea that his thoughts, writing, and ideas continued to travel beyond him, connecting with others and moving outward into the world.
Of one of the portraits, Kisoon said, “I did this painting for myself to remember him as an enlightened person.” Her words give both works their emotional center. These are not simply portraits of Doug’s appearance. They are portraits of memory—of the thinker, writer, husband, and person she continues to hold in her mind and heart.

A Wider Conversation
From 2009 through 2023, Doug shared his work with a wider audience through Healthy Memory. The blog began with the subjects closest to his professional expertise: human memory and cognition, mnemonic techniques, cognitive health, and what he called “transactive memory”—the ways other people and technology can extend and support the knowledge held by an individual mind. Over time, it became a much broader inquiry into consciousness, creativity, education, belief, judgment, human relationships, social behavior, aging, and wisdom.
Doug frequently began with the work of another researcher or writer and then followed the ideas wherever they led. He drew upon Daniel Schacter’s research into the strengths and failures of memory; Annie Murphy Paul’s examination of how thinking extends beyond the brain into movement, physical surroundings, and other people; Rutger Bregman’s challenge to cynical assumptions about human nature; and Dilip Jeste and Scott LaFee’s exploration of the scientific and neurological foundations of wisdom. These were not the limits of his reading, but they illustrate its range—from cognitive psychology and neuroscience to education, society, morality, and the question of how human beings might live more thoughtfully.
Doug did more than summarize what he read. He examined the evidence, connected new findings with earlier research, questioned assumptions, and considered what an idea might mean beyond the laboratory. A discussion of memory could lead to lifelong learning and cognitive resilience. Research on expectations could become an inquiry into education, leadership, and the dignity with which people are treated. Studies of empathy, cooperation, and power could open into larger questions about the stories societies tell about human nature. Again and again, Doug moved from how the mind works to how knowledge about the mind might help people make wiser choices.
The 79 writings preserved on this website were selected by Kisoon. They are not intended to represent every subject Doug addressed or to rank one period of his work above another. Together, they preserve the qualities of his thinking that she most wanted others to encounter: his fascination with cognition and memory, his concern for the human condition, his resistance to easy cynicism, and his enduring interest in compassion, altruism, human potential, and wisdom. Through her selections, readers can follow not only the subjects that mattered to Doug, but the movement of his mind—how he encountered an idea, tested it against evidence, connected it with other questions, and asked what it might mean for the way people live.
Doug died on December 10, 2025, at the age of seventy-nine. What he left behind is more than a body of professional research or a collection of writings. His work preserves the record of a mind that remained engaged: examining evidence, revisiting assumptions, and carrying scientific questions into the practical and moral circumstances of human life.
His presence also endures in the life he shared with Kisoon, in the friendships sustained through years of conversation, and in the questions and convictions he placed into words. Through these writings, readers can encounter not only what Doug thought, but how he worked his way toward understanding.
