The psychology of failures and the ethical/legal implications are highlighted. The approach aims to provide a comprehensive understanding of the challenges associated with integrating reasonably foreseeable user failure and misuse into the design process. By taking a proactive approach to failure and misuse, designers can not only increase product safety, but also stimulate innovation that takes into account a wide range of user behaviour, including in unexpected circumstances.enghuman errorhuman behaviourhuman-centred designsocio-technical systemsarticle10.1017/pds.2024.108
