Calculus of Voice

Tom Geraghty · Voice & Silence, Power, Individual & Wellbeing

The mechanism beneath psychological safety: before every act of voice a rapid, usually unconscious risk assessment runs — what Detert and Burris (2007), building on Ashford et al., called an 'affect-laden expectancy-like calculus'. Kish-Gephart, Detert, Treviño and Edmondson (2009) reserve 'calculus' for only the slow, weighed version of this and treat fast, automatic silence as a separate freeze response outside it; this piece pushes back — a computation doesn't stop being a computation for running too fast to notice, any more than stepping over a kerb stops being your body computing trajectory and clearance — and reads their four-part typology (freeze, fast schema-match, slow deliberation, habituated automaticity) as four speeds and routes the calculus can take rather than four alternatives to it. We weigh the potential costs of speaking up (lost status, exclusion, embarrassment, punishment, more work) against the potential benefits, and lean toward silence when the costs win. The inputs vary enormously between people: cultural and religious background shapes what counts as acceptable challenge and who it's acceptable to challenge; neurodivergence affects how social signals and ambiguity are processed; socioeconomic history leaves an imprint on who we learned gets to speak. Past experience forms the dataset — two people can run the same calculation on very different data. Crucially the calculus produces four outputs, not two: speaking fully, silence, softening (the common, under-discussed middle — phrasing as a question, hedging, mitigating, as in PACE), and outright changing the message to please or appease. Local rationality reframes silence and softening as sensible given a person's goals, knowledge and reading of the situation — so blaming individuals for behaving as the system encouraged is the wrong diagnosis. The mechanism is psychological and internal, but the conditions that load it are social and structural: the work is to reduce the costs of speaking up and increase the benefits, while supporting those who must navigate the conditions in the meantime. Voice here means any intentional act of communication, not just spoken words — narrowing it to speech excludes exactly those who most need to be heard.
