The article builds on how current legal punitive and regulatory anticorruption instruments miss ethically troublesome, but not necessarily unlawful, practices rooted in a corrupt institutional culture that normalizes nepotism, lobbying influence and other legally grey practices. It develops an analytical and normative philosophical toolkit centered on the corrupt dispositional sets—the mindset—of public officeholders, and reframes anticorruption initiatives as the promotion of a pro‑office mindset within an institutional ethics of office. The article discusses the limits and prospects of existing instruments, introduces the notion of the mindset, reconsiders anticorruption through the lenses of the mindset of public officeholders, and illustrates anticorruption measures that the approach justifies.
