Gregor Jeffrey
Gregor Jeffrey is a British-Canadian cognitive theorist whose work explores the architecture of human thought—how we process information, form meaning, and navigate the invisible terrain of cognitive difference. His research reframes communication, collaboration, and neurodiversity in modern systems by examining cognition as the foundation of human interaction.
Gregor Jeffrey identified that many breakdowns in professional and personal performance are not primarily behavioral or emotional, but cognitive—rooted in fundamental differences in how individuals perceive, organize, and relate to information. This insight led to the development of Cognitive Spectrum Theory, an integrative framework that maps the diversity of mental processing. At the core of CST is a reframing of conditions such as ADHD and ASD—not as disorders, but as high-spectrum expressions of cognition.
Building on this foundation, Gregor Jeffrey created methodologies including the Cognitive Sequence Method and Dyadic Cognitive Mapping, which are applied by leading organizations to improve team dynamics, reduce cognitive friction, and foster more inclusive decision-making cultures. His work continues to expand the theoretical and applied understanding of cognitive diversity as a central dimension of human systems.
