This study was conducted to understand the concept of binary thinking and the collective psychological process of human thinking. Binary thinking is a concept that humans naturally made to impair our ability to figure out and organize our thoughts in a simple manner and to avoid the fear of the uncertainty. It impairs us from breaking out of that overly-simplified mindset, but also could be seen as a helpful tool for us to process our thoughts. Thus, binary thinking is just a tool for us to use and to leverage, which can allow us to facilitate in-depth complex thinking. Without the awareness that binary thinking is a tool, we will box ourselves in duality. By first organizing the problem, the target audience, and the personas to help further develop a solution, the project proceeds with an interactive visual experiment—a gamified decision-making mobile application service that delivers categorically organized lists with time stamps, game-like visualization to help enjoy a stress-free thinking in general, and accelerating difficulty levels to stimulate mind more effectively and directionally. The user evaluation, then, was executed to collect some data as to how this helps and influences users. As a result, using binary thinking as a tool to guide users to think more fluidly and make decisions in a visually enjoyable and in a stress free manner was shown to be, so far, successful.
