Congratulations to SUIS Gubei students Hannah Wu, Givenny Liang, Jacqueline Jiang, and Bella Li on their success in the 2025 Brain Challenge. Their team project “The Influence of Different MBTIs on Brain Waves When Performing Specific Behaviors” earned first place in the Research Project Section.
From Daily Chats to Brainwave Data:
Our Journey to Decoding the Neuroscience of MBTI
We are thrilled to share the story of our project, a journey from casual conversations into the intricate world of neuroscience. This report chronicles our quest to find a unique link between the popular MBTI personality test and measurable brain activity.
Our initial challenge was standing out. We brainstormed numerous neuroscience concepts but feared they were too common or academic. We needed a golden ticket—a topic that was both unique and relatable. This prompted a strategic shift: we moved away from specialized themes to focus on concepts embedded in daily life. Our attention kept returning to the MBTI. Its popularity as a tool for self-understanding made it the perfect relatable entry point to bridge complex science and public curiosity.
However, our biggest hurdle emerged: connecting psychological theory to neurological data. As Givenny Liang noted, “developing a topic that focused on neuroscience proved to be quite challenging.” We cycled through vague, irrelevant ideas, a frustrating period that taught us the need for a sharply defined question. Our breakthrough came from online forums discussing how brain regions might influence MBTI type. This was our eureka moment. It led us to a pivotal question: could we measure differences in brain activity between MBTI types?
We narrowed our focus to the stark decision-making contrast between Thinking (T) and Feeling (F) types. This clear dichotomy allowed us to formulate our precise, testable hypothesis: exploring the differences in brainwaves between T and F types during specific behaviours. We had finally found our direction—a unique topic grounded in rigorous science.
The experimentation phase was humbling. We struggled with technical issues, from setting up EEG equipment to designing tasks that effectively triggered decision-making processes. The reality of working with raw neural data was daunting. We often faced messy, confusing signals, and as one member Hannah Wu recalled, “The major hurdle was interpreting the data; it was difficult to draw a clear conclusion from the messy signals.” There were moments when results defied our expectations.
Yet, these setbacks became our greatest teachers. We learned to adapt, simplify our methods, and persevere through meticulous troubleshooting. Each solved problem built our resilience and technical competence.
In conclusion, this project was about much more than data. It was a profound lesson in interdisciplinary innovation. We learned how a familiar concept like MBTI can be transformed into meaningful research, connecting daily conversations to measurable science. We are incredibly proud of what we’ve accomplished. From the anxiety of finding a topic to the thrill of collecting clean data, this journey has been unforgettable. We hope our work inspires others to find the science hidden in their everyday lives.
What is Brain Challenge Competition?
The Brain Science Innovation Challenge (Brain Challenge) aims to encourage students to transform knowledge of brain science into practical solutions that address real-world problems in the field of brain science. It is organized by the China Organizing Committee of the Brain Bee.
