In 1895, Breuer and Freud opened the door to a century of psychoanalytical interpretations of human behavior in their Studies on Hysteria, positing the thesis that hidden sexuality and aggression are the invisible conductors of our lives. Although psychoanalysis in its original form did not achieve full scientific validation over time, it inadvertently foreshadowed what we call today evolutionary psychology—a discipline that reveals how sex, status, and instincts permeate almost every fragment of our daily lives.

On the surface, we choose rationally. But beneath the surface? Things look quite different.
A man does not buy an expensive sports car simply because he loves speed. A woman does not invest hours into a flawless look and impeccable style solely because “she does it for her own soul.” Even the ambitious professional who tirelessly builds a career and chases top results often does so from motives rooted much deeper in our evolutionary code—because power, status, and success have always meant the same thing: a better position and a greater choice.
When Ambition Turns into a Power Game
Renowned psychologist David Buss launched a bold theory that virtually every male competition and struggle for dominance has a deep evolutionary and sexual basis. Authors Malcolm Potts and Thomas Hayden went a step further, presenting the compelling thesis that the very foundations of wars and conflicts throughout history can be traced back to innate competition for resources and partners.
Evolutionarily speaking, this dynamic divides into:
- Direct jealousy: The instinctive need to protect what is ours and preserve our own territory.
- Indirect jealousy: Subtler forms of rivalry, such as when a man feels a threat to his prestige, social standing, or authority.
In the world of ancient humans, loss of reputation meant loss of status, and loss of status automatically meant reduced access to resources and partners. Eliminating competition—whether directly or through social dominance—was a clean, efficient survival mechanism. There were no courts or laws; the winner secured the passage of their genes into the future.

What Does This Mean for Us Today?
Renowned biologist Dobzhansky once stated: “Nothing in biology makes sense except in the light of evolution.”
When applied to our daily lives, it becomes clear that neither our subtlest choices, ambitions, nor crises in relationships can be fully understood without an awareness of these ancient mechanisms. People who truly wish to rule their world and understand the game of power around them must first master the rules that nature long ago built into our DNA.
True power does not come from ignoring one’s instincts, but from completely understanding what drives us from the shadows.
