The Hedgehog model is a theoretical framework widely used in the social sciences and psychology to explain the interactions and relationships between individuals and groups. The core concept of this model is to understand the behavior patterns of individuals in the face of others, especially in intimate relationships and cooperation, through different survival strategies.

The metaphor of the hedgehog model comes from hedgehogs in nature. When the temperature plummets, hedgehogs curl up into a ball to protect themselves from the cold. In this process, the hedgehog's thorn is equivalent to the symbol of this protective mechanism, suggesting that in the face of potential threats, individuals often take avoidance or defense strategies out of self-protection. This behavior is especially pronounced when forming close relationships with others, and the individual may refuse further contact and communication for fear of being hurt or losing control.

In the hedgehog model, the distance and proximity between individuals form a delicate balance. Too close, may cause each other's thorns to stab each other, causing emotional harm; Keeping a distance, on the other hand, can protect both parties from conflict and misunderstanding. The dynamic of this balanced relationship reflects the challenge people often face in intimate relationships, finding the appropriate boundary between the desire for intimacy and the need to remain who they are.

The model also applies to teamwork and social interaction. In a team, members may be too close to each other, causing friction, which in turn affects the overall performance of the team. At this point, the team needs to find a balance between cooperation and competition to ensure that the common goal is achieved without losing individual independence and creativity. Individuals need to learn when to show vulnerability and when to protect themselves in order to strengthen team cohesion.
