How the Iceberg Theory Transforms Game UI Design: From Conscious to Unconscious

1. What Is the Iceberg Theory

In 1895, psychologist Sigmund Freud and his collaborator Breuer published a study that became the prototype of the iceberg theory, describing the mind as an iceberg where only a small visible tip (consciousness) is above water while the vast majority of mental activity lies hidden beneath the surface (preconscious and unconscious).

The model divides the psyche into three layers: the top visible layer is conscious , the middle layer is preconscious , and the deep hidden layer is unconscious .

Ernest Hemingway later noted that an iceberg’s grandeur comes from the part hidden below water, illustrating the metaphor’s literary appeal.

Consciousness is merely a part of preconsciousness; preconsciousness sits between consciousness and unconsciousness, acting as a monitor that prevents raw instincts from entering conscious awareness, which explains why we sometimes feel we cannot control ourselves or why a random object can trigger a distant memory.

2. Applying the Iceberg Theory to Interface Design

Basic UI design addresses players’ conscious actions, providing solutions for their explicit goals. The deeper layers, however, offer richer design opportunities.

Preconscious Design and Its Application (Preconscious)

According to Freud, preconscious content is not currently in awareness but can be recalled. In game UI, this translates to leveraging players’ memories and latent thoughts to guide actions and create resonance.

Examples include using nostalgic symbols such as flying pigeons delivering letters in a historical‑setting game, or employing childhood origami patterns in "Shen Du Night Walk" to instantly evoke familiar feelings.

Designers can analyze gameplay functions to tap into players’ preconscious memories, thereby enhancing emotional attachment and nostalgia.

Unconscious Design and Its Application (Unconscious)

Unconscious behavior influences daily actions without deliberate thought, such as automatically adjusting glasses or tapping a leg. Designing for these actions is challenging but rewarding.

Naoto Fukasawa introduced the concept of “unconscious design,” where conscious UI triggers an unconscious response, creating a seamless experience. For instance, a cooking app might automatically add a common seasoning when the user forgets it.

In games, unconscious design means crafting continuous player behaviors, such as:

Continuous Behavior 1: Insufficient In‑Game Items – When a player lacks an item, the UI should instantly present acquisition options, forming a closed loop.

Continuous Behavior 2: Empty State – Instead of a static “no results” screen, provide contextual next steps, such as prompting players to request items from other players.

Continuous Behavior 3: Payment Loop – When currency is low, suggest the nearest recharge amount to reduce decision friction and improve conversion.

These designs guide players through actions without requiring conscious deliberation, creating a smooth, uninterrupted experience.

3. Conclusion

The visible tip of the iceberg represents only a fraction of the player’s mind; the hidden bulk lies beneath. Effective game UI design must address not only conscious interactions but also the preconscious memories and unconscious habits that drive deeper engagement.
