A Different Way of Understanding Human Behavior
For nearly forty years, I have studied Choice Theory psychology. Its roots trace back to 1960, when William T. Powers introduced Perceptual Control Theory—an engineering-based theory proposing that living organisms control their perceptions rather than simply reacting to stimuli.
Psychiatrist William Glasser, the creator of Reality Therapy®, recognized that Powers’ work provided a theoretical foundation for what he was already practicing clinically. With Powers’ permission, Glasser began teaching what he initially called Control Theory. Over time, as he expanded the framework—most notably by introducing the five basic human needs and the concept of Total Behavior—he sought and received permission to rename his expanded model “Choice Theory.”
In 1998, Glasser published Choice Theory: A New Psychology of Personal Freedom, solidifying the model as a distinct psychology of internal control.
At the time, theories of human behavior were often divided into two broad camps:
- Behavior is driven primarily by external circumstances.
- Behavior is internally motivated and directed toward fulfilling personal needs.
Choice Theory falls into the second category. It proposes that all behavior is purposeful—our best attempt, in any given moment, to get what we want to best meet our basic needs.
Your belief about what drives behavior fundamentally shapes the questions you ask. Someone operating from external control thinking may ask, “How do I control this?” Someone grounded in internal control thinking asks, “What choices do I have here?”
The Core Premise: Internal Control
Choice Theory suggests that we are genetically driven by five basic human needs:
- Survival
- Love & Belonging
- Power
- Freedom
- Fun
In modernizing the language of Choice Theory, Mental Freedom® reframes these as:
- Safety & Security
- Connection
- Significance
- Freedom
- Joy
While the strength of each need tends to remain fairly stable, the degree to which each is satisfied fluctuates. When a need feels unmet, we are motivated to reduce that gap. Our behavior represents our best available strategy, given our knowledge and skills at the time.
Choice Theory distinguishes between internal control and external control behaviors. We cannot control other people’s actions, thoughts, or feelings—though we often try. Complaining, blaming, criticizing, nagging, threatening, punishing, and even rewarding are attempts to influence others externally. While these behaviors may feel justified in the moment, they often erode agency and strain relationships rather than strengthen them.
Total Behavior: Acting, Thinking, Feeling, Physiology
In William Glasser’s biography Champion of Choice, written by Jim Roy, Glasser described Total Behavior as the concept he was most proud of.
Choice Theory defines behavior as consisting of four inseparable components:
- Acting
- Thinking
- Feeling
- Physiology
These components operate together as a unified whole. When something isn’t working in our lives, we often become most aware of our emotions or physical sensations. However, we have the most direct influence over our actions and thoughts.
Glasser used the metaphor of steering a car: we cannot turn the rear wheels to change direction. We steer by adjusting the front wheels. Similarly, when we want to influence how we feel or how our body responds, we begin by examining and adjusting our thinking and actions.
The Five Basic Needs
Human behavior is internally motivated by the ongoing pursuit of what we want in order to satisfy one or more of our five basic needs:
Connection – belonging, affiliation, love, friendship, collaboration
Freedom – autonomy, independence, creativity, choice
Significance – achievement, competence, influence, contribution
Safety & Security – physical well-being, stability, financial and environmental safety
Joy – pleasure, play, discovery, contentment
These needs operate from the inside out. We do not act primarily because of circumstances; we act in pursuit of satisfying needs within us.
Why Choice Theory Still Matters
Choice Theory has had both supporters and critics since its introduction. Some consider it overly simple. Others have misunderstood its perspective on mental illness. Regardless of where one lands in those debates, its core contributions remain relevant.
Choice Theory encourages:
- Responsibility without blame
- Agency without shame
- Relationship repair without coercion
These principles remain deeply needed in personal, professional, and societal contexts today.
How Mental Freedom Builds on Choice Theory
Mental Freedom is rooted in Choice Theory. Over decades of clinical work, coaching, and relational experience, I found that while people resonated with internal control thinking, many struggled to apply it compassionately—especially in moments of emotional intensity.
Mental Freedom translates Choice Theory into lived, relational practice. It integrates emotional awareness with responsibility and emphasizes application over abstraction. Readers and participants do not need to study theory extensively to benefit from its principles.
If you’d like to see how these principles are applied as a practical framework for real conversations and relationships, you can read more about Mental Freedom here.
What might change if you focused less on controlling circumstances—and more on expanding your choices?
