Originally established at UCL in the early 1970’s as a weekly Cognition and Reasoning seminar, it later became an intercollegiate seminar on Language and Cognition in the early 1980’s. The name LJDM was finally coined in 1990, and the group has been running seminars under this name ever since, with lecturers and researchers in and around the UK meeting on a regular basis to discuss judgment and decision-making, judgments of likelihood, reasoning, thinking, problem solving, forecasting, risk perception and communication, and other related topics.
The LJDM seminar series is supported by:
University College London
City, University of London
Kings College London
Unless specified otherwise, all seminars take place on Wednesdays from 5:15-6:15 PM UK time. The seminar series will be held in a hybrid format via Zoom as well as at University College London.

Title: Value, Goals and Abstractions in Decision Making
Abstract: In the fields of neuroscience and machine learning, “value” has often been used interchangeably with “reward,” emphasising its hedonic aspect while neglecting its functional, concept-like nature. However, in real life, we rarely receive discrete numerical rewards at the end of our actions and need to build our own values. In this talk, I will present some work from our lab that challenges the canonical view that equates value and reward by showing how the brain is able to construct the value of an option or action on-the-fly by building abstractions that flexibly adapt to changing goals. I will demonstrate how this mechanism can facilitate learning and foster generalisation. Overall, I will discuss how rethinking the true nature of value is both feasible and necessary.

Title: Stakeholder safety action: patients and families intervening to prevent medical errors in hospitals.
Abstract: Research in healthcare finds that patients and families frequently intercede in the decision-making and work of clinicians in order to prevent adverse events (e.g., wrong diagnosis). This is significant for research on safety and risk, because it suggests that external stakeholders (e.g., service-users) can act as form of ‘safety net’ for catching errors and addressing problems in decision-making within organisations. I explored this idea by theorizing the concept of ‘stakeholder safety action’: this relates to stakeholders engaging in voicing (e.g., speaking-up) and correcting (e.g., fixing mistakes) behaviours in order to resolve perceived errors within an organisation and prevent them from causing harm. I investigated safety action by undertaking a quantitative and qualitative analysis of 1,857 written complaints sent by patients and families to UK hospitals about experiences of unsafe treatments. The analysis found patients routinely reported engaging in voicing and correcting behaviours, with these being elicited by concerns about decision-making (e.g., in making diagnoses, dispensing medicines) being missed or not resolved by staff. Through these behaviours, and depending on how staff responded to them, patients described trying to prevent accidents in three escalating ways: helping staff to avoid errors (e.g., during diagnoses), pushing into clinical work to resolve perceived mistakes (by changing medications), and bypassing teams and hospitals judged irredeemably unsafe. I surmise that stakeholder safety action contributes to organizational safety by acting as an important – yet external and often unrecognised – source of resilience within organisations.
