Against the backdrop of crisis decision-making requiring indecision and split-second reactions, the study takes the reader on a journey through various decision-making contexts, whether it is a crisis and its aftermath, a corporate or medical environment, and negotiations through legal proceedings. Includes a series of case studies and analyzes that highlight the role of language populations and protocols in emergency services, the impact of language change on organizational culture, or the success of different language strategies in multinational environments. The empirical findings in the text highlight the link between language use and decision outcomes, in a way that demonstrates its transformative power in shaping collective action and power relations. The subsequent text highlights implications for both professionals and decision-makers, all of which highlight the need for ongoing reflective engagement with language use to ensure more inclusive and effective decision-making processes.
