Confusion plays a central role in entrepreneurial learning, as venture creation often unfolds under dynamic and uncertain conditions. Disruptions such as crises or conflicts can lead to dysfunctional routines, triggering cognitive dissonance or emotional distress. These experiences may stimulate deep learning processes, encouraging entrepreneurs to reassess existing mental models and routines and develop new value creation strategies. However, not all individuals possess the same cognitive and emotional capacities to effectively process such events. While prior research emphasizes the transformative potential of confusion, empirical investigations have largely relied on self-reports, which may be limited due to biases, memory constraints, or the implicit nature of cognitive and affective responses. To address this methodological gap, this study introduces an innovative approach to research on entrepreneurial learning by using electrodermal activity (EDA) to measure physiological arousal during confusing events in venture creation contexts. Since skin conductance reflects stress-related changes in sweat gland activity, EDA provides real-time insights into how entrepreneurs react to uncertainty and disruption. By capturing these immediate physiological responses, the study aims to improve the understanding of confusion as both a stressor and a catalyst in entrepreneurial learning and venture development. This contributes to a more nuanced view of how individuals experience and adapt to discontinuities, highlighting the need for objective, process-oriented measurement tools in entrepreneurship research.
