Psychological science is currently going through major transformations, moving towards “Big Team Open Science” with many promising large-scale collaborative initiatives aiming to tackle major challenges in science and society. Psychological Science Accelerator (PSA), Framework for Open and Reproducible Research Training (FORRT), and the Many Labs consortiums include hundreds of researchers from over 80 countries around the world. These mass-collaborations are resulting in remarkable achievements from promoting a science reform in identifying and building credible research to testing global interventions addressing the COVID-19 pandemic and climate change. 

I will provide an overview of key projects and findings from “CORE team” that I have been coordinating in the past 4 years, briefly touching on my experiences from taking part in PSA and FORRT. Collaborative Open-science REsearch (CORE) is a large-scale initiative to systematically map and integrate findings in the domains in the judgment and decision-making and social psychology literatures. With a team of over 50 early career researchers from around the world and over 300 students in Hong Kong, we completed over 100 studies, 10 meta research projects, and over 20 collaborative guides and templates. We covered many topics, from heuristics and biases to morality, and we are most recently focused on leveraging gained insights towards optimizing effectiveness of altruism and promoting solutions aimed at increasing flourishing and reducing pain and suffering.
