Jack Yang

Jack Yang is an independent researcher, author, and consultant whose work focuses on complex systems, judgment, execution, and the relationship between information and real-world action.

His research has led to several interconnected frameworks, including Runtime Intent (RI), Predictive Environment Theory (PET), and Structural OS. These works examine how systems move from information and judgment to executable action, how decisions evolve under changing conditions, and how structure can help preserve consistency in complex environments.

Alongside his theoretical work, Jack has extensive experience in complex ICT projects, particularly in the airport sector. His professional background has shaped his interest in how people, systems, rules, and operational environments interact in practice.

His books span several areas, including complex systems, decision-making, crypto trading, education, entrepreneurship, and airport operations. Although the subjects differ, they share a common concern: how people understand uncertain environments, make judgments before action, manage risk, and preserve the ability to adapt when conditions change.

Jack writes not to offer simple answers, but to develop practical frameworks for seeing structure more clearly and acting with greater discipline under uncertainty.
