Leader's Safety Culture and Human Psychophysiology

The Human Factor Through the Prism of Neurobiology

The traditional approach to HSE often relies on administrative measures and regulations, overlooking the basic physiological mechanisms that govern worker behavior. Developing a safety culture is impossible without understanding how the brain reacts to stress, fatigue, and external pressure. During his presentation, Evgeny Parygin, Safety Culture Advisor at SNIIP JSC, analyzes the psychophysiological aspects of leadership in detail and explains why classic punishment methods often lead to the opposite effect in hazardous industries.

Two Systems of Thinking: Why Instructions Don't Always Work

Drawing on the research of Nobel laureate Daniel Kahneman, the speaker shows that a person is capable of staying in an analytical (critical) thinking mode for no more than 25 – 30% of their working time. The remaining 70 – 75% of actions are performed automatically.

Automatic thinking is divided into positive (based on established safe habits) and negative (arising from a lack of time, fatigue, or an overload of complex information). The leader's task is to structure work processes so that during moments of automatic action, the worker relies on positive patterns rather than making instinctive mistakes under the pressure of circumstances.

The Physiology of Stress: The Price of a Single Reprimand

A harsh management style and a culture of punishment have a specific physiological cost. When a stressful situation occurs, cortisol — the anxiety hormone — is released into the bloodstream. The speaker cites research data: under the influence of severe stress, a worker's memory deteriorates by 40%, intellectual potential drops by 50%, and the speed of motor reactions decreases by 30 – 40%.

It is critically important to understand that a person's psychophysiological transition from a state of stress back to a zone of adequate analytical thinking takes about 2.5 hours. By punishing an employee with shouting or a harsh reprimand in the workplace, a manager effectively excludes them from a safe production process for several hours, multiplying the risk of an accident.

Team Evolution: From Fear to Awareness

The presentation details three stages of safety culture development through the prism of "us vs. them" communicative tactics:

• Level of Fear. The worker is guided by the thought "what will happen to me?". Coercion and fear of punishment dominate. This is a resource-intensive and least effective model.
• Level of Shame. A transitional stage where the motivation is the thought "what will my peers think of me?". Responsibility to the team arises, but indifference to external rules remains.
• Level of Conscience. The highest stage, based on self-control and internal motivation. Safety becomes a personal value rather than an imposed requirement.

To transition to higher levels, a leader must use empathy tools and build an atmosphere of trust, stimulating the production of reward hormones (dopamine, serotonin) that neutralize the effects of stress.

Generational Theory in Safety Management

Communication effectiveness directly depends on the value orientations of employees. Using the nuclear industry as an example, the speaker shows how work approaches differ across generations. While status, collectivism, and team spirit are important for "Baby Boomers," Generation X is characterized by pragmatism and individualism, and Generation Y is focused on comfort and interesting work. Ignoring these differences leads to a situation where the manager's correct messages are simply not perceived by subordinates.
