In this episode of Better Thinking, Nesh Nikolic speaks with Arthur Thomas Ware about fostering long, happy, and purposeful years in retirement, and how psychology can help us create meaning beyond work. Arthur Thomas Ware (He prefers to be called, Tom) will be turning ninety in April next year. He was born in the U.K. and came to Australia as a “Ten Pound Pom” in 1951. From that year he had a variety of jobs: Post Office, Navy, Aviation, Electrical Power, Truck Driver, Foundry Laborer, Lab Assistant, NSW Police and even a year as an Antarctic Expeditioner. His final work was the usual 9 to 5 in a government office job. He worked for 44 years and took voluntary redundancy in 1995.

In this episode of Better Thinking, Nesh Nikolic speaks with Dr Joanna Moncrieff about her latest book: A Straight Talking Introduction to Psychiatric Drugs: The Truth About How They Work and How to Come Off Them. Dr Joanna Moncrieff is a practising psychiatrist, part-time academic, and author with a deep interest in the history, philosophy, and politics of psychiatry. Her work focuses particularly on the use, misuse, and misrepresentation of psychiatric drugs. She became interested in drug treatment because of its dominance in contemporary approaches to managing the suffering and disturbances labeled as mental disorders. She recognised that embedded in the understanding of drugs such as ‘antipsychotics’ and ‘antidepressants’ was an unexamined assumption: that these drugs ‘work’ by correcting a hypothetical abnormality or ‘chemical imbalance.’ Moncrieff has termed this the ‘disease-centred’ model of drug action and has developed an alternative ‘drug-centred’ model, which highlights the ways psychiatric drugs alter brain and body function, modify feelings and behaviour, and interact with the difficulties associated with mental disorders. Alongside colleagues from around the world, Moncrieff has worked to expose the misconceptions that arise from the disease-centred model, clarify the effects psychiatric drugs produce, and question the narratives that sustain current prescribing practices. She also emphasises that psychiatry is a profoundly political enterprise, shaped by social and political imperatives to neutralise distress and manage disturbing behaviour. Beyond her work on psychiatric drugs, she is interested in how emotional and behavioural problems might be conceptualised differently, as well as the broader politics of healthcare.

In this episode of Better Thinking, Nesh Nikolic speaks with Associate Professor Jacqueline Anderson about the long-term impact of traumatic brain injuries and how they affect cognition, identity, and daily life. Jacqueline Anderson, PhD, is an Associate Professor in Clinical Neuropsychology in the Melbourne School of Psychological Sciences.

Clinical work roles have primarily been in acute tertiary referral public hospitals, but have also included roles in rehabilitation settings; she has worked in private practice for many years, including undertaking medico-legal work. A/Prof. Anderson’s research program specialises in abnormal cognitive functioning. She and her lab members use a combination of clinical and laboratory-based tools to investigate adult patient populations with neuropsychological disorders. Her research interests primarily relate to outcome after mild traumatic brain injury (mTBI) in community-based adults. In particular, she is focused on investigating the neuropsychological (cognitive, behavioural, psychological) and neuropathological aetiologies of individual patient variation in outcome after mTBI as well as developing interventions for individuals who experience poor recovery. She has a further specific interest in abnormalities of attention and memory, executive function and subcortical cognitive networks in the context of neuropsychological disorders.

In this episode of Better Thinking, Nesh Nikolic speaks with Dr. David Healy about how psychotropic drugs and clinical trials have influenced the way we understand mental health and the broader impact these developments have had on society.

In this episode of Better Thinking, Nesh Nikolic speaks with Lana Tikhomirov about the intersection of AI and human decision-making, exploring its ethical concerns, cognitive challenges, and growing role in high-stakes fields like healthcare. Lana Tikhomirov is an AI safety researcher at the Australian Institute for Machine Learning, where she focuses on developing ethical, human-centered artificial intelligence systems for medical decision-making. Her interdisciplinary PhD bridges cognitive science, bioethics, and AI safety, examining a core question: How do humans make decisions using AI algorithms—and where should we draw the ethical line when replacing human judgment with machine logic? Lana’s work addresses the nuanced challenges that emerge when advanced deep learning systems—often opaque and difficult to interpret—are integrated into high-risk, real-world environments. As these technologies become increasingly common in critical domains, understanding their influence on human cognition and decision-making has never been more urgent. She is committed to advancing responsible and safe AI, and her research contributes to national policy and ethical guidelines for AI development and implementation in Australia.

In this episode of Better Thinking, Nesh Nikolic speaks with Dr Poppy Watson about compulsive reward-seeking behavior, commonly seen in drug or gambling addiction, but also in more subtle forms that influence our everyday actions and habits. The research interests of Dr Poppy Watson lie at the intersection of motivation, attention and choice behaviour. A fundamental question in human psychology is whether we are totally in control of the choices we make and the extent to which we rely on environmental cues to guide our decisions. She is interested in the conflict that arises between our ‘good intentions’ (for example to eat healthily or avoid alcohol) and our innate tendency to be attracted by things that signal reward such as the McDonald’s golden M or the beer logo. She uses methods such as eye tracking and neuroimaging to examine this interplay between biased cognitions and habits on the one hand and explicit motivation on the other. She tries to understand the mechanisms that contribute to unwanted patterns of behaviour in both healthy and clinical populations. She is also involved in intervention projects (to improve treatment outcomes for patients and measuring the efficacy of these interventions) and is interested more generally in health psychology and behaviour change.
