Introduction to Neuroeconomics and POE 2Neuroeconomics is an interdisciplinary field that combines neuroscience psychology and economics to study how people make decisions. It examines the neural mechanisms behind economic behavior and sheds light on the cognitive processes influencing financial choices.

commonly known as POE 2 is an upcoming action role-playing game with a complex in-game economy. One of the most fascinating aspects of its economy is the concept of currency flipping where players buy and sell in-game currencies such as Chaos Orbs and Divine Orbs to make profits. This practice involves strategic decision-making and risk assessment making it an ideal subject for neuroeconomic research
fMRI as a Tool to Study Decision-MakingFunctional Magnetic Resonance Imaging or fMRI is a non-invasive imaging technique that measures brain activity by detecting changes in blood flow. In studies on risk-taking behavior fMRI allows researchers to observe which regions of the brain are activated when participants make decisions involving uncertainty and potential rewards. By applying fMRI to study currency flipping in POE 2 scientists can identify the neural correlates of economic behavior in a digital context
Methodology of the StudyParticipants in the study were experienced POE players with a history of engaging in currency flipping. During the experiment they were shown a series of in-game trading scenarios on a screen while undergoing fMRI scanning. Each scenario presented different risk levels and potential rewards based on fluctuating in-game market values. Players were asked to decide whether to buy sell or hold specific currency items while their neural responses were recorded in real time. The study focused on brain regions associated with decision-making such as the prefrontal cortex the amygdala and the striatum
Key Findings on Risk-Taking BehaviorThe fMRI data revealed that high-risk currency flipping scenarios led to increased activity in the ventromedial prefrontal cortex a region linked to value assessment and emotional regulation. Additionally the amygdala showed heightened activation indicating the presence of emotional arousal during uncertain outcomes. Players who consistently opted for high-risk trades showed a stronger response in the nucleus accumbens a region associated with reward anticipation. These patterns suggest that currency flipping in POE 2 engages similar neural circuits as real-world financial decision-making
Implications for Game Design and Behavioral EconomicsThe findings from this study provide valuable insights for both game developers and economists. Understanding the neural basis of in-game economic decisions can help developers design more engaging and psychologically balanced trading systems. For behavioral economists the results highlight the relevance of virtual economies as experimental platforms for studying risk-taking behavior in a controlled environment. The digital setting of POE 2 allows for repeated trials and a vast range of variables making it an effective tool for modeling complex decision-making processes
Future Directions in Neuroeconomic ResearchAs virtual economies become increasingly sophisticated researchers can leverage games like POE 2 to explore broader questions about human behavior. Future studies may incorporate real-time feedback dynamic pricing systems and social interactions to deepen our understanding of the cognitive and emotional underpinnings of economic choices. The integration of neuroimaging techniques with interactive gaming environments marks a significant step forward in the field of neuroeconomics offering a unique lens through which to examine the human mind in action
