Introduction to Human Communication and Behavior
Many people find that conversations with certain individuals flow naturally, while interactions with others feel incredibly difficult. It is common to assume that those who do not understand us or who behave differently are simply difficult or incompetent. Thomas Erikson once encountered a successful entrepreneur named Sture who took this perspective to the extreme, claiming he was surrounded by idiots. Sture’s inability to understand his employees led to a toxic environment where staff even used a warning light to avoid him. This conflict highlighted a fundamental truth that the people Sture labeled as idiots were simply individuals whose communication styles differed from his own.
True communication requires moving beyond the habit of using oneself as the benchmark for normal behavior. When we label others as arrogant, tedious, or rude, we are often reacting to a mismatch in behavioral patterns rather than a lack of intelligence. To bridge this gap, a framework known as the DISA system categorizes human behavior into four primary types based on Dominance, Inducement, Submission, and Analytic ability. Each type is represented by a color: Red, Yellow, Green, and Blue. By identifying these patterns, it becomes possible to adapt to how others function instead of dismissing them entirely.
Effective communication is not defined by what is said, but by what the other person hears. Every message sent is filtered through the listener’s personal biases, past experiences, and unique perspective. Because of this, it is rare for a message to be received exactly as it was intended. While it can be frustrating to realize how little control one has over a listener’s interpretation, the responsibility for clarity ultimately lies with the speaker. To be understood, one must adapt their delivery to match the listener’s needs rather than relying on their own preferred style.
Flexibility is the hallmark of a great communicator. Since most people function differently than we do, sticking to a single way of speaking ensures we will be misunderstood by the majority. By adjusting our behavior to create a secure environment for others, we allow them to focus their energy on the message itself rather than reacting defensively to an unfamiliar communication style. This does not mean one's natural personality is wrong; rather, it suggests that certain social approaches are better suited for specific situations and specific people.
Behavior is ultimately shaped by a mix of heredity and environment. Before birth, genetics establish a foundation of traits inherited from parents and ancestors, much like inheriting physical traits. At the center of a person’s character are core values, which are fundamental beliefs about right and wrong learned in childhood that rarely change. Layered over these are attitudes formed through later life experiences, which can shift over time. Understanding these layers makes it possible to see the real person beneath their outward actions and adjust our communication accordingly.
