We employ a novel experimental design utilizing escape rooms as a noninterventional social laboratory, enabling us to capture real-time interactions among 40 teams engaged in problem-solving activities. We find that team familiarity has a negative influence and a suppression effect on success. Faultline affects team success negatively when faultline-induced subgroups do not communicate enough with each other. Our work contributes to a better understanding of complex processes and interdependencies that lead to team success or failure.enginfo:eu-repo/semantics/openAccesscross-subgroup communicationdiversity faultlinesescape roomfamiliarityproblem-solvingteamsSocial PsychologyApplied PsychologyJournal articlehttp://www.scopus.com/inward/record.url?scp=85164156296&partnerID=8YFLogxKO.
