The foundational text of commons scholarship, and the work for which Ostrom would later receive the Nobel Prize in economics; this corpus already holds her 2010 lecture, but the 1990 book is where the argument originates. Ostrom's target is the received wisdom, crystallised in Hardin's tragedy of the commons and in the prisoner's dilemma and collective-action models that formalised it, that a shared resource open to many users will inevitably be overused and destroyed unless it is either privatised (the market solution) or placed under central authority (the Leviathan solution). Against this she sets a large body of empirical cases of common-pool resources, mountain grazing commons in Torbel, Japanese village forests, Spanish and Philippine irrigation systems, that have been governed sustainably for centuries by the very people who use them, through neither market nor state but self-organised institutions. From the successes and failures she induces eight design principles associated with enduring self-governance: clearly defined boundaries; congruence between rules and local conditions; collective-choice arrangements that let those affected by rules participate in making them; monitoring by accountable monitors; graduated sanctions; accessible low-cost conflict resolution; recognition by external authorities of the right to organise; and, for larger systems, nested enterprises. The relevance to psychological safety is foundational rather than incidental, and it underwrites a distinctive line of argument in this corpus: psychological safety is better understood as a commons, a shared resource that a group collectively produces, sustains, and can deplete, than as a programme a leader dispenses. The two poles Ostrom rejects have direct organisational analogues in the leader-provides-safety model (a form of central provision) and the incentivise-speaking-up model (a form of market design), and her third way, self-governance through institutions the participants themselves shape, is the register in which safety is taken rather than granted. The design principles offer a concrete institutional grammar for how a group governs the conditions of candour: who has standing, how the rules get made and by whom, how breaches are handled proportionately, how disputes are resolved cheaply enough that people keep using voice rather than exiting. As no open-access full text of the book exists, this node is built from the book's own framework as set out across cross-checked secondary sources (the publisher's synopsis, scholarly reviews, and commons-studies summaries) rather than from the primary text directly.
