What plays the decisive role in managing behavior? What can be read on faces, and how does it define the quality of our lives? Paul Ekman, the world-renowned expert in the psychology of emotions, opens up the world of micro-expressions and emotional programs so that we can understand ourselves, read others, and communicate effectively.

Imagine your boss invites you to a meeting without an agenda. The secretary only hints that "it's very important." How do you react? Fear, anger, sadness, or excitement? Your reaction—what you say and do—will determine the outcome. Will you rely on your emotional control, or will you need a sedative?

It is difficult not to behave emotionally when the stakes are high. Emotions are our best guides, suggesting actions suitable for the situation. However, this isn't always the case. Sometimes we act on impulse and regret it later. Yet, turning off emotions completely would make us seem detached or cold.

The goal is to experience the fullness of emotions but express them constructively. Aristotle defined this long ago: emotions should be proportionate to the event, expressed at the right time, and in the right way, without causing harm.

Our emotions are not strictly private. Most have specific signals telling others what we feel. Unlike thoughts, which are private, emotions are visible. The emotional signal system is always "on." It’s an evolutionary trait: for the survival of the species, it was useful for others to know our state (e.g., a child crying for help).

We must avoid the "Othello Error"—misinterpreting the source of an emotion. A person might look terrified not because they are lying (as Othello thought of Desdemona), but because they are afraid of not being believed.

When an emotion is triggered, a cascade of changes occurs that we do not consciously choose:

Ekman uses the metaphor of "emotional response programs." These are open systems: some instructions are evolutionary (fear of heights), while others are learned through our own experience. We cannot overwrite innate programs, but we can modify learned habits. This is difficult because once an emotion is triggered by an automatic appraisal, it cannot be interrupted instantly—it has to run its course.

Can we manage this process? Yes, by developing a specific type of consciousness—mindfulness. This is the ability to take a step back during an emotional episode and ask yourself: "Do I want to continue acting under the influence of this feeling?"

To develop this skill, Ekman advises analyzing your reactions retrospectively. The best tool for this is keeping a record. Regular analysis helps identify your personal "hot triggers." For systematic self-improvement, the Diary of Emotions | EQ (Emotional Intelligence) is the ideal tool. It is structured to help you record not just the event, but your reaction, bodily sensations, and thoughts at the moment of the flare-up.

We cannot always control emotional behavior, especially when tired or when the emotion is too strong. But the key to success is self-knowledge. By analyzing our emotional episodes, we turn unconscious reactions into conscious choices, improving relationships with loved ones and colleagues.
