Dr. Flannagan will talk about a study that she led in 2013-2015 during the Transatlantic Trade and Investment Partnership (TTIP) (EU-US trade) negotiations. The study evaluated whether EU-regulated cars and US-regulated cars could be deemed "equally safe." She will focus on the methods and some of the political context for this study that made the choice of methods critical. In the study, she and her colleagues used both Bayesian and non-Bayesian methods, but she'll focus on the Bayesian approach that they took. Although the particular study is closer to Epidemiology than Psychology per se, it has obvious parallels to any situation in which the question of "are these the same" is of great importance. In addition, the sponsor had a particular point of view that had implications for the methods the team used and the conclusions they could draw.
