Human behaviour

Human behavior is explained through a mix of biology, past experience, and environment. Learners are introduced to the idea that the brain evolved for survival, not for modern health goals, which helps explain why people are drawn to eat when food is available, rest when possible, avoid risk, focus on problems, and seek approval from others. These built-in tendencies can make behavior change difficult. The lesson also shows how habits, beliefs, values, and identity shape daily actions. Repeated behaviors become automatic, and beliefs such as “exercise is dangerous when I have back pain” can block change. Identity matters too: if someone sees themselves as inactive, change becomes harder. A central point is that behavior always has a function, so resistance or lack of follow-through should be approached with curiosity rather than judgment. Practical skills for change include replacing autopilot reactions with conscious choices, noticing progress, and continuing despite setbacks. An example with a patient named John illustrates how pausing, observing thoughts and feelings, and asking deliberate questions can shift someone from automatic habits to more helpful decisions.
