The Field Guide › Paper
Kahn's paper is the one the field treats as the origin of psychological safety as a workplace construct, though it is more accurately the first sustained articulation of the idea in organisational behaviour than its invention. Kahn draws openly on earlier thinking he names: Schein and Bennis (1965) on the safety people need before they will change, Carl Rogers on the therapeutic conditions that let a person explore, and, clinically, Sandler (1960) on 'the background of safety'. What Kahn adds is to gather these into a single named condition and ground it in the fine grain of working life. Across two qualitative, theory-generating field studies (summer-camp counsellors and members of an architecture firm) he asks when people bring their 'preferred self' into a role and when they hold it back, distinguishing personal engagement (employing and expressing the self physically, cognitively and emotionally in a role) from personal disengagement (withdrawing and defending it). People, he argues, tacitly put three questions to each situation and engage or disengage on the answers: how meaningful is it to bring myself in, how safe is it to do so, and how available am I to do so. These are the three psychological conditions of meaningfulness, safety and availability. Psychological safety itself is defined as feeling able to show and employ oneself 'without fear of negative consequences to self-image, status, or career' (1990: 708), and is experienced where situations are trustworthy, predictable and non-threatening. Kahn locates its sources in supportive, trusting interpersonal relationships; in group and intergroup dynamics, including the unconscious roles people are cast into (his architecture firm organises itself around a 'father' figure, with 'mother', 'favoured son' and 'bad son' characters who enjoy very different room to speak); in a management style that is supportive, consistent and non-punitive; and in organisational norms clear enough that people know the boundary they are working within. Throughout, the felt safety to engage tracks power and status: people withdraw faster from conflict with those above them than with peers, and those cast into low-status roles find the least room to bring themselves in. The study is explicitly descriptive rather than confirmatory (its ratings illustrate the model rather than test it) and individual and experiential rather than group-level, but it supplies the definition of psychological safety that later group-level work, above all Edmondson's, would take up, refine and carry into teams.
