The Impostor Phenomenon (IP) impacts a significant portion of the Software Engineering (SE) workforce, yet it is often viewed primarily through an internal individual lens. In this position paper, we propose framing the prevalence of IP as a form of “Human Debt” and discuss the relation with the ICSE2026 Survey results. Similar to technical debt, which arises when short-term goals are prioritized over long-term structural integrity, this human debt accumulates due to gaps in psychological safety and inclusive support within socio-technical ecosystems. We observe that this debt is not distributed equally, it weighs heavier on underrepresented engineers and researchers, who face compounded challenges within traditional hierarchical structures and academic environments. We propose “Active Maintenance” through allyship and cultural refactoring, suggesting that leaders and institutions must address the environmental factors that exacerbate these feelings, ensuring a sustainable ecosystem for all professionals.
