About this episode
Researchers are heavily reliant on statistical techniques that are based on large sample sizes. Therefore, attempts to gain useful information from small samples can often lead to biased, or incorrect conclusions. Dr Rens van de Schoot at Utrecht University has shown that the limitations associated with small samples sizes can be overcome by using an alternative method – Bayesian estimation – as an all-encompassing approach to quantitative research. However, this approach comes at a price: expert knowledge must be integrated into the statistical model.

Dr John Kershner | Understanding the Causes and Brain Mechanisms Behind Dyslexia
Individuals with dyslexia encounter difficulties in learning to read, despite possessing a normal level of intelligence and having access to qualified teachers and educational materials. However, the causes of dyslexia remain disputed. One suggestion is that dyslexia may be related to stress, either experienced by the afflicted individual at a young age, or through inheriting stress-related biological changes from their parents. Dr John Kershner, a neuropsychologist at the University of Toronto, has conducted extensive research on this alternative hypothesis and provides compelling evidence to support this emerging concept.

Dr. Matthew Sherrer | An Infinite Game Mindset for Enhanced Cooperation in Anesthesia
Anesthesia in the US is currently delivered through a team-based approach, with physician anesthesiologists supervising certified registered nurse anesthetists. However, in over 20 states, there is no requirement for nurse anesthetists to be supervised by anesthesiologists, allowing them to work independently. This has resulted in a bitter turf war over the rights and responsibilities of physicians and advanced practice nurses working in this discipline to provide patient care, paving the way for daily acrimony and a toxic working environment. The mindset behind this adversarial approach can be compared with a “finite game”, where there are clear winners and losers. Aiming to challenge this dysfunctional tribalism, Dr. Matthew Sherrer from the University of Alabama Birmingham and colleagues have drawn on an alternative mindset: the infinite game.
Professor Pei Wang | Defining AI to Ensure Effective Research and Policymaking
Artificial intelligence – or AI – is receiving increasing attention for its rapid development and potential to change society. Researchers are working hard to develop its capabilities, while regulators are racing to ensure it is managed and governed properly. But what do we mean by AI, and how can we define such a complex term? In a recent paper, Professor Pei Wang at Temple University argues that the lack of an agreed definition makes it difficult for policymakers to assess what AI will be capable of in the near future, or even which kinds of AI are desirable. To combat this, he discusses what makes a robust definition, and suggests his own.
