This interactive e-learning game turns the idea of bias into an engaging mystery. Participants become detectives who work through clues, suspects, and motives to solve a fictional case, only to realise how assumptions shape their reasoning. Each clue mirrors real workplace decisions about hiring, collaboration, and feedback. As they progress, learners receive instant feedback, helping them see how bias works in real time. The course ends with a practical guide on applying critical thinking and fairness to daily work choices, encouraging curiosity and awareness over instinctive conclusions.
