Can simulation-based learning shift how residential property investors actually make decisions, where conventional training and disclosure regimes have not? We're testing whether the simulator format can operationalise the UN's housing-as-a-human-right framework into recognisable investor behaviours and protocols. The experiment is building the simulator with the UNGP framework and Bell's work as the rubric, piloting it with a small cohort of institutional and individual residential property investors, and documenting both the design decisions and what the cohort's choices reveal about common failure modes.
