The hollow square arrangement is particularly effective for fostering discussion among participants. This configuration allows all members to see one another, which encourages engagement and interaction. The openness of the layout promotes a sense of equality, as participants are placed at the same level, facilitating a free exchange of ideas and opinions.

In contrast to configurations that favor a singular presenter or focus on individual tasks—such as a traditional classroom setup or rows of desks—the hollow square's design promotes a collaborative atmosphere. This encourages active participation and allows for a dynamic flow of conversation, making it ideal for group discussions, brainstorming sessions, or any setting where dialogue is essential to the learning process.
