2024

  • 17th April 2024, Improving The Research Funding Lottery at School of Architecture, University of Sheffield.

    • Researchers spend hours and hours writing funding proposals and in the end bad ideas get funded and good ideas get missed. Everyone has the suspicion that the funding process is biased against people in the wrong fields, from the wrong institutions or with the wrong backgrounds. Can research funding be improved, and what does the evidence say? Tom will talk about work from the Research on Research Institute, and about projects on innovations in how research funding is awarded.https://researchonresearch.org/

  • 10th April 2024, Research on Research at School of Psychology Research Day, University of Sheffield.

  • 9th February 2024, Adventures in the Multiverse at TARG, University of Bristol

    • Complex data and complex methods mean multiple statistical analyses are potentially legitimate. Multiverse analysis offers a tool to interrogate the stability of results under different analysis choices. After introducing the general history and rationale of multiverse analysis, I will talk about two multiverse projects I have been involved in, both in my research area of bias and decision making, and what we have learned from them

  • 19th January 2024 6pm UK time, Google IQ Research Talk: When people are wrong on the internet - reasons to be optimistic (host Mevan Babakar)

    • Human reasoning in the digital age has a terrible reputation. People are often portrayed as hopelessly biased, polarised and resistant to good sense, while - strangely - also being easily manipulated by malevolent forces and bizarre fads. From the trenches of psychological science, I bring you good news! I will discuss two strands of work. In the first, we show that even minimal deliberation allows online groups to select away from intuitive but wrong answers (and that there are prospects for language-model based dialogue agents to support good group reasoning). More at delibot.xyz. In the second strand of research we show that, across polarising topics, UK partisans are surprisingly good at representing the views of the ideological opponents, and that the better people are at this the more likely they are to view people they disagree with as moral, informed and rational. More in Brand, Brady & Stafford (2023).

  • 23 March and 14 April 2022 - Understanding the brain through the eyes
    What we see and how we see can be used to help us understand how the brain works. Illusions are not just visual tricks, but illustrate the deep principles which our brains use to construct reality. In this talk, with the use of many examples, I will show how the study of illusions provides important lessons for psychologists trying to understand all aspects of mind, brain and behaviour

  • 16 June 2021 - Why you should use decision models with your response time and accuracy data at Centre for Cognition and Neuroscience, University of Huddersfield (and online).

    Decision modelling is increasingly accessible and yields highly practical benefits to experimental psychologists. This talk will explain why and how you should apply decision models to your data.

    Response time and accuracy are fundamental measures of behavioural science, but discerning participants’ underlying abilities can be masked by speed-accuracy trade-offs (SATOs). SATOs are often inadequately addressed in experiment analyses which focus on a single variable or which involve a suboptimal analytic correction. Models of decision making, such as the drift diffusion model (DDM), provide a principled account of the decision making process, allowing the recovery of SATO-unconfounded decision parameters from observed behavioural variables.

    I will show, using simulations and worked examples from experimental data, how decision models allow potentially massive increases in statistical power at the same time as helping you avoid mistaken inferences due to variations in participants’ SATOs strategies. Because the modelling community has focussed on differences between different decision models, this has disguised the fact that there is now a consensus around the core mechanisms which define the family of plausible decision models, as well as increasing agreement on tools for fitting behavioural data with these decision models.
